| .................... //// //// |
| .................... //// Library for adding a virtual COM port on your PC over USB using //// |
| .................... //// the standard Communication Device Class (CDC) specification. //// |
| .................... //// Including this file in your code will add all USB code, //// |
| .................... //// interrupts, descriptors and handlers required. No other //// |
| .................... //// modifications need to be made. //// |
| .................... //// //// |
| .................... //// This library creates a virtual RS232 link between the PC and //// |
| .................... //// the PIC, therefore the library provided will be familiar to //// |
| .................... //// anyone with standard UART stream I/O: //// |
| .................... //// //// |
| .................... //// usb_cdc_kbhit() - Returns TRUE if there is one or more //// |
| .................... //// character received and waiting in the receive buffer. //// |
| .................... //// //// |
| .................... //// usb_cdc_getc() - Gets a character from the receive buffer. If //// |
| .................... //// there is no data in the receive buffer it will wait until //// |
| .................... //// there is data in the receive buffer. If you do not want //// |
| .................... //// to wait in an infinit loop, use usb_cdc_kbhit() first to //// |
| .................... //// check if there is data before calling usb_cdc_getc(). //// |
| .................... //// //// |
| .................... //// usb_cdc_putc(char c) - Puts a character into the transmit //// |
| .................... //// buffer. If the transmit buffer is full it will wait until //// |
| .................... //// the transmit buffer is not full before putting the char //// |
| .................... //// into the transmit buffer. The transmit buffer is read by //// |
| .................... //// the PC very quickly, and therefore the buffer should only //// |
| .................... //// be full for a few milli-seconds. If you are concerned //// |
| .................... //// and don't want to be stuck in a long or infinite loop, //// |
| .................... //// use usb_cdc_putready() to see if there is space in the //// |
| .................... //// transmit buffer before putting data into the transmit //// |
| .................... //// buffer. //// |
| .................... //// //// |
| .................... //// usb_cdc_putready() - Returns TRUE if there is room left in the //// |
| .................... //// transmit buffer for another character. //// |
| .................... //// //// |
| .................... //// usb_cdc_connected() - Returns TRUE if we received a //// |
| .................... //// Set_Line_Coding. On most serial terminal programs (such //// |
| .................... //// as Hyperterminal), they will send a Set_Line_Coding //// |
| .................... //// message when the program starts and it opens the virtual //// |
| .................... //// COM port. This is a simple way to determine if the PC //// |
| .................... //// is ready to display data on a serial terminal program, //// |
| .................... //// but is not garaunteed to work all the time or on other //// |
| .................... //// terminal programs. //// |
| .................... //// //// |
| .................... //// usb_cdc_putc_fast(char c) - Similar to usb_cdc_putc(), except //// |
| .................... //// if the transmit buffer is full it will skip the char. //// |
| .................... //// //// |
| .................... //// usb_cdc_line_coding - A structure used for Set_Line_Coding and //// |
| .................... //// Get_Line_Coding. Most of the time you can ignore this. //// |
| .................... //// //// |
| .................... //// usb_cdc_break - If the PC has sent a break command, this will //// |
| .................... //// hold the break time (in milli-seconds). If the PC sends //// |
| .................... //// a value of 0xFFFF the device is supposed to hold the //// |
| .................... //// break until it sends a value of 0 //// |
| .................... //// //// |
| .................... //// usb_cdc_carrier - Where Set_Control_Line_State value is stored. //// |
| .................... //// Of most relevance is the field dte_present, which is the //// |
| .................... //// DTR setting. //// |
| .................... //// //// |
| .................... //// The following functions are also provided, and are ports of the //// |
| .................... //// I/O functions in input.c. See input.c and the CCS manual for //// |
| .................... //// documentation: //// |
| .................... //// get_float_usb() - Read a float number from the user //// |
| .................... //// get_long_usb() - Read a long number from the user //// |
| .................... //// get_int_usb() - Read an integer number from the user //// |
| .................... //// get_string_usb(char *s, int max) - Read a string from the user. //// |
| .................... //// gethex_usb() - Read a byte, in HEX, from the user //// |
| .................... //// gethex1_usb() - Read a HEX character //// |
| .................... //// //// |
| .................... //// This driver will load all the rest of the USB code, and a set //// |
| .................... //// of descriptors that will properly describe a CDC device for a //// |
| .................... //// virtual COM port (usb_desc_cdc.h) //// |

| .................... //// March 5th, 2009: //// |
| .................... //// Cleanup for Wizard. //// |
| .................... //// PIC24 Initial release. //// |
| .................... //// //// |
| .................... //// Nov 26th, 2007: //// |
| .................... //// usb_cdc_put_buffer_free() should be more stable. //// |
| .................... //// Fixed a hang-up that would happen if you sent //// |
| .................... //// exactly 64 bytes. //// |
| .................... //// //// |
| .................... //// Nov 6th, 2007: //// |
| .................... //// Compatabible with latest pic18_usb.h, which //// |
| .................... //// reduces RAM footprint of USB driver. //// |
| .................... //// This driver now fits on 18F4450/2450 PICs. //// |
| .................... //// //// |
| .................... //// October 27th, 2005: Changed the way incoming packets are //// |
| .................... //// handled in that CDC driver will not flush //// |
| .................... //// endpoint until user has handled all data. This //// |
| .................... //// will prevent overflows as the USB will NAK //// |
| .................... //// incoming packets until it is ready to receive //// |
| .................... //// more. //// |
| .................... //// When using 18F4550 family, the RX buffer is //// |
| .................... //// mapped directly to the endpoint buffer - this //// |
| .................... //// saves a chunk of RAM. //// |
| .................... //// When using the 18F4550 family, you can increase //// |
| .................... //// the TX and RX size over 64 bytes. //// |
| .................... //// No longer send 0len packets in the TBE interrupt. //// |
| .................... //// Hopefully fixed bugs that caused random crashes //// |
| .................... //// if you tried sending more than 64 bytes. //// |
| .................... //// //// |
| .................... //// July 6th, 2005: Global interrupts disabled when writing to TX //// |
| .................... //// buffer. //// |

| .................... //// find useful to use in your application. //// |
| .................... //// //// |
| .................... //// *********** NOTE ABOUT 18F2450/4450 LIMITATIONS ********** //// |
| .................... //// Due to the limited USB RAM of this family, a limitation of //// |
| .................... //// this driver is that there are only 3 endpoints (0, 1 and 2). //// |
| .................... //// The HW actually supports more endpoints, but to simplify //// |
| .................... //// driver development this driver will only support the first 3 //// |
| .................... //// so there is an easier memory block to work with. //// |
| .................... //// //// |
| .................... //// USB_MAX_EP0_PACKET_LENGTH will also be set to 8 regardless //// |
| .................... //// of USB speed, to save RAM. //// |
| .................... //// //// |
| .................... //// ************** NOTE ABOUT HW REQUIREMENTS **************** //// |
| .................... //// If you are not using internal pullups, you will need to put //// |
| .................... //// an internal pullup resistor on D+ or D+ depending on if you //// |
| .................... //// want to use slow speed or full speed. This code configures //// |
| .................... //// the device to use internal pullups, see usb_init() if you //// |
| .................... //// want to change that. //// |
| .................... //// //// |
| .................... //// You need approximately 470nF cap on Vusb, even if you are //// |
| .................... //// using the internal 3.3V USB regulator. //// |
| .................... //// //// |
| .................... //// To run at full speed, you must use the oscillator //// |
| .................... //// configuration (PLLx) to set the PLL divide to 4MHz. You can //// |
| .................... //// configure the MCU clock to any speed (up to 48MHz) but the //// |
| .................... //// PLL must run at 4Mhz to provide the USB peripheral with a //// |
| .................... //// 96MHz clock. See the datasheet for details. //// |
| .................... //// //// |
| .................... //// To run at slow speed you must configure your MCU to run at //// |
| .................... //// 24Mhz. See the datasheet for details. //// |
| .................... //// //// |
| .................... //// **************** NOTE ABOUT INTERRUPTS ****************** //// |
| .................... //// This driver uses INT_USB. It requires INT_USB to interrupt the //// |
| .................... //// PIC when an event has happened on the USB Bus. Therfore //// |
| .................... //// this code enables interrupts. A user modification can be made //// |
| .................... //// to poll the USB interrupt flag instead of relying on an //// |
| .................... //// interrupt. //// |

| .................... //// * 4553 family added. //// |
| .................... //// //// |
| .................... //// Dec 18, 2007: //// |
| .................... //// * usb_kbhit() moved to device driver. //// |
| .................... //// * USB Token handler changed to workaround a flaw in the USB //// |
| .................... //// peripheral to prevent the USB peripheral from //// |
| .................... //// inadvertantly STALLing the endpoint. Happened most often //// |
| .................... //// in bulk demo applications, especially CDC. //// |
| .................... //// //// |
| .................... //// 11-6-07: Fixed a bug where usb_data_buffer[] was reserving //// |
| .................... //// too much RAM. //// |
| .................... //// USB_MAX_EP0_PACKET_LENGTH value can be overwritten. //// |
| .................... //// For the 18F4450/2450 family this should be 8 //// |
| .................... //// because of limited RAM. Reducing this value //// |
| .................... //// frees RAM for application. //// |
| .................... //// Based upon which endpoints have been configured for //// |

| .................... //// usb_init() - Initializes the USB stack, the USB peripheral and //// |
| .................... //// attaches the unit to the usb bus. Enables //// |
| .................... //// interrupts. Will wait in an infinite loop until //// |
| .................... //// the device enumerates - if you are using //// |
| .................... //// connection sense or if the processor should run //// |
| .................... //// even if it's not connected to USB then use //// |
| .................... //// usb_init_cs() instead. //// |
| .................... //// //// |
| .................... //// usb_init_cs() - A smaller usb_init(), does not attach unit //// |
| .................... //// to usb bus or enable interrupts. Since this does //// |
| .................... //// not attach to the USB, you must periodically call //// |
| .................... //// usb_task(). See usb_task() for more information. //// |
| .................... //// //// |
| .................... //// usb_task() - If usb_init_cs() was used to initiate the USB //// |
| .................... //// peripheral, usb_task() should then be called periodically //// |
| .................... //// to check the connection sense pin. If the connection //// |
| .................... //// sense pin denotes USB is connected and the USB peripheral //// |
| .................... //// is not attached, this will attach the USB peripheral //// |
| .................... //// so the PC can start the enumeration process (and it //// |
| .................... //// will enable interrupts). If the connection sense pin //// |
| .................... //// denotes USB is not attached and the USB peripheral is //// |
| .................... //// running, this will reset the USB peripheral and wait //// |
| .................... //// for USB to reconnect (and usb_enumerated() will start //// |
| .................... //// returning FALSE). If connection sense (USB_CON_SENSE_PIN) //// |
| .................... //// is not defined the usb_task() assumes that USB is always //// |
| .................... //// connected. //// |
| .................... //// //// |
| .................... //// usb_attached() - Returns TRUE if the device is attached to a //// |
| .................... //// USB cable. A macro that looks at the defined //// |
| .................... //// connection sense pin. If this returns TRUE //// |
| .................... //// it does not mean the PC has connected to it, //// |
| .................... //// you need to use usb_enumerated() to check this. //// |
| .................... //// //// |
| .................... //// usb_enumerated() - Returns TRUE if device has been enumerated //// |
| .................... //// (configured) by host, FALSE if it has not. //// |

| .................... //// //// |
| .................... //// March 5th, 2009: //// |
| .................... //// Cleanup for Wizard. //// |
| .................... //// PIC24 Initial release. //// |
| .................... //// //// |
| .................... //// Dec 14, 2007: //// |
| .................... //// usb_kbhit() moved to device driver. //// |
| .................... //// //// |
| .................... //// July 13th, 2005: //// |
| .................... //// usb_puts() packet_size and this_packet_len changed to 16bits. //// |
| .................... //// usb_gets() len, packet_size and this_packet_len to 16bits. //// |
| .................... //// //// |
| .................... //// June 20th, 2005: //// |
| .................... //// Initial 18fxx5x release. //// |
| .................... //// usb_kbhit() removed, usb_kbhit() now implemented in hardware //// |
| .................... //// layer. //// |
| .................... //// //// |
| .................... //// May 13th, 2005: //// |
| .................... //// Beta release, only works with 18Fxx5x hardware layer. //// |
| .................... //// Now supports multiple interfaces (many defines in descriptors //// |
| .................... //// will have to be changed, see examples) //// |
| .................... //// TODO: alot of indexing and length handling for descriptors is //// |
| .................... //// only 8bit, so make sure all descriptor tables are less than //// |
| .................... //// 256 bytes long. //// |
| .................... //// //// |
| .................... //// Apr 21st, 2005: //// |
| .................... //// Initial Alpha Release with PIC18Fxx5x support. (ONLY TESTED //// |
| .................... //// WITH 18F4550) //// |
| .................... //// usb_puts() doesn't need max packet size as a paremeter, uses //// |
| .................... //// usb_ep_tx_size[] defined in usb.h //// |
| .................... //// usb_puts() timeout parameter now in ms, not seconds. //// |
| .................... //// USB Stack no longer buffers incoming data. If there is data to //// |
| .................... //// get usb_kbhit(en) will return TRUE and the data will sit in //// |
| .................... //// the endpoint buffer until you usb_get_packet(), which will //// |
| .................... //// then free the endpoint buffer for more data. This affects //// |
| .................... //// routines such as usb_gets() and usb_kbhit(). //// |
| .................... //// usb_gets() no longer reads buffered data (see above note), //// |
| .................... //// now it reads multiple packets in the same way usb_puts() //// |
| .................... //// writes multiple packets //// |
| .................... //// usb_kbhit() is hardware specific, so has been moved to hardware //// |
| .................... //// layer. //// |
| .................... //// //// |
| .................... //// Nov 11th, 2004: //// |
| .................... //// No longer includes wrong descriptor header. //// |
| .................... //// //// |
| .................... //// June 24th, 2004: //// |
| .................... //// Optimization and cleanup. //// |
| .................... //// The following definitions changed: //// |
| .................... //// USB_EPx_TX_ENABLE and USB_EPx_RX_ENABLE have changed. See usb.h //// |
| .................... //// USB_CONFIG_DESCRIPTORS[] removed //// |
| .................... //// USB_CONFIG_DESC_LEN changed to USB_DESC_CONFIG_LEN //// |
| .................... //// USB_INTERFACE_DESC_LEN changed to USB_DESC_INTERFACE_LEN //// |
| .................... //// USB_CLASS_DESC_LEN changed to USB_DESC_CLASS_LEN //// |
| .................... //// USB_ENDPOINT_DESC_LEN changed to USB_DESC_ENDPOINT_LEN //// |
| .................... //// USB_CONFIG_DESC_KEY changed to USB_DESC_CONFIG_TYPE //// |
| .................... //// USB_INTERFACE_DESC_KEY changed to USB_DESC_INTERFACE_TYPE //// |
| .................... //// USB_CLASS_DESC_KEY changed to USB_DESC_CLASS_TYPE //// |
| .................... //// USB_ENDPOINT_DESC_KEY changed to USB_DESC_ENDPOINT_TYPE //// |
| .................... //// USB_STRING_X[] arrays removed, see USB_STRING_DESC[] and //// |
| .................... //// USB_STRING_DESC_OFFSET[] //// |
| .................... //// dev_req, curr_config, status_device and getdesc_type global //// |
| .................... //// variables moved into struct USB_stack_status //// |
| .................... //// //// |
| .................... //// December 5th, 2003: Fixed a potential bug where descriptors are //// |
| .................... //// evenly dividable by 8 (MAX_EP0_PACKET_SIZE) //// |
| .................... //// //// |
| .................... //// October 15th, 2003: Support for boot protocol added. //// |
| .................... //// Set USB_HID_BOOT_PROTOCOL to TRUE to support this. //// |
| .................... //// The array hid_protocol[] saves which protocol mode each //// |
| .................... //// interface is in. It is your applications job to send //// |
| .................... //// data that either fit the boot protocol or HID protocol. //// |
| .................... //// //// |
| .................... //// May 6th, 2003: Fixed a potential stack overflow using PCM //// |
| .................... //// //// |
| .................... //// October 28th, 2002: Problem with usb_puts and timeout fixed. //// |
| .................... //// //// |
| .................... //// October 28th, 2002: Typo fixed in get_next_string_character(), //// |
| .................... //// although it didn't cause any serious problems //// |
| .................... //// //// |
| .................... //// October 25th, 2002: Another change to usb_puts() was made to fix //// |
| .................... //// problems with multiple packet messages //// |
| .................... //// October 29th, 2002: Fixed a problem with multiple packet string //// |
| .................... //// descriptors that require a 0 len packet to //// |
| .................... //// end message. //// |
| .................... //// //// |
| .................... //// October 23rd, 2002: usb_puts() will bomb out of error quicker //// |
| .................... //// //// |

| .................... //// //// |
| .................... //// These are the functions that are meant to be called by the user: //// |
| .................... //// //// |
| .................... //// usb_init() - Initializes the USB stack, the USB peripheral and //// |
| .................... //// attaches the unit to the usb bus. Enables //// |
| .................... //// interrupts. Will wait in an infinite loop until //// |
| .................... //// the device enumerates - if you are using //// |
| .................... //// connection sense or if the processor should run //// |
| .................... //// even if it's not connected to USB then use //// |
| .................... //// usb_init_cs() instead. //// |
| .................... //// //// |
| .................... //// usb_init_cs() - A smaller usb_init(), does not attach unit //// |
| .................... //// to usb bus or enable interrupts. Since this does //// |
| .................... //// not attach to the USB, you must periodically call //// |
| .................... //// usb_task(). See usb_task() for more information. //// |
| .................... //// //// |
| .................... //// usb_task() - If usb_init_cs() was used to initiate the USB //// |
| .................... //// peripheral, usb_task() should then be called periodically //// |
| .................... //// to check the connection sense pin. If the connection //// |
| .................... //// sense pin denotes USB is connected and the USB peripheral //// |
| .................... //// is not attached, this will attach the USB peripheral //// |
| .................... //// so the PC can start the enumeration process (and it //// |
| .................... //// will enable interrupts). If the connection sense pin //// |
| .................... //// denotes USB is not attached and the USB peripheral is //// |
| .................... //// running, this will reset the USB peripheral and wait //// |
| .................... //// for USB to reconnect (and usb_enumerated() will start //// |
| .................... //// returning FALSE). If connection sense (USB_CON_SENSE_PIN) //// |
| .................... //// is not defined the usb_task() assumes that USB is always //// |
| .................... //// connected. //// |
| .................... //// //// |
| .................... //// usb_attached() - Returns TRUE if the device is attached to a //// |
| .................... //// USB cable. A macro that looks at the defined //// |
| .................... //// connection sense pin. If this returns TRUE //// |
| .................... //// it does not mean the PC has connected to it, //// |
| .................... //// you need to use usb_enumerated() to check this. //// |
| .................... //// //// |
| .................... //// usb_enumerated() - Returns TRUE if device has been enumerated //// |
| .................... //// (configured) by host, FALSE if it has not. //// |
| .................... //// Do not try to use the USB peripheral for //// |
| .................... //// sending and receiving packets until you //// |
| .................... //// are enumerated. //// |
| .................... //// //// |
| .................... //// usb_wait_for_enumeration() - Sits in an infinte loop until device //// |
| .................... //// is enumerated. //// |
| .................... //// //// |
| .................... //// usb_tbe(endpoint) - Returns TRUE if the endpoint transmit buffer //// |
| .................... //// is free and ready to accept a new packet for transmission. //// |
| .................... //// //// |
| .................... //// usb_put_packet(endpoint, ptr, len, tgl) - Sends one packet to the //// |
| .................... //// host. If you need to send a message that //// |
| .................... //// spans more than one packet then use //// |
| .................... //// usb_puts(). Fore more detailed documentation //// |
| .................... //// see usb_hw_layer.h //// |
| .................... //// //// |
| .................... //// usb_puts(endpoint, ptr, len, timeout) - Sends a multiple packet //// |
| .................... //// message to the host. If you only need to send one packet, //// |
| .................... //// it is more effecient to use usb_put_packet(). This is //// |
| .................... //// documented in more detail above the prototype in USB.H. //// |
| .................... //// //// |
| .................... //// usb_kbhit(endpoint) - Returns true if OUT endpoint contains data //// |
| .................... //// from host. This will remain TRUE until //// |
| .................... //// usb_put_packet() or usb_flush_out() used. //// |
| .................... //// This function will return an invalid response //// |
| .................... //// if specified endpoint is not enabled for //// |
| .................... //// receiving data. //// |
| .................... //// //// |
| .................... //// len = usb_get_packet(endpoint, ptr, max) - Gets one packet that //// |
| .................... //// from the host/PC. usb_kbhit() must return TRUE before you //// |
| .................... //// call this routine or your data may not be valid. This //// |
| .................... //// only receives one packet, if you are trying to receive a //// |
| .................... //// multi-packet message use usb_gets(). For more detailed //// |
| .................... //// documentation see usb_hw_layer.h. //// |
| .................... //// //// |
| .................... //// len = usb_gets(endpoint, ptr, max, timeout) - Gets multiple //// |
| .................... //// packets from the host, you would use this instead //// |
| .................... //// of usb_get_packet() if you wanted to handle multi-packet //// |

| .................... //// //// |
| .................... //// March 5th, 2009: //// |
| .................... //// Cleanup for Wizard. //// |
| .................... //// PIC24 Initial release. //// |
| .................... //// //// |
| .................... //// July 13th, 2005: //// |
| .................... //// usb_ep_tx_size[] and usb_ep_rx_size[] changed to 16bits //// |
| .................... //// //// |
| .................... //// June 20th, 2005: //// |
| .................... //// Initial 18fxx5x release //// |
| .................... //// //// |
| .................... //// May 13th, 2005: //// |
| .................... //// Beta release, only works with 18Fxx5x hardware layer. //// |
| .................... //// Now supports multiple interfaces (many defines in descriptors //// |
| .................... //// will have to be changed, see examples) //// |
| .................... //// //// |
| .................... //// Mar 21st, 2005: //// |
| .................... //// Initial Alpha Release with PIC18Fxx5x support. (ONLY TESTED //// |
| .................... //// WITH 18F4550) //// |
| .................... //// usb_gets() and usb_puts() changed (see usb.c) //// |
| .................... //// //// |
| .................... //// June 24th, 2004: //// |
| .................... //// Optimization and cleanup. //// |
| .................... //// The following definitions changed: //// |
| .................... //// USB_EPx_TX_ENABLE and USB_EPx_RX_ENABLE have changed. See usb.h //// |
| .................... //// USB_CONFIG_DESCRIPTORS[] removed //// |
| .................... //// USB_CONFIG_DESC_LEN changed to USB_DESC_CONFIG_LEN //// |

| .................... //// //// |
| .................... //// March 5th, 2009: //// |
| .................... //// 18F14K50 family added. //// |
| .................... //// Cleanup for Wizard. //// |
| .................... //// PIC24 Initial release. //// |
| .................... //// //// |
| .................... //// Nov 3rd, 2008: //// |
| .................... //// * 4553 family added. //// |
| .................... //// //// |
| .................... //// Dec 18, 2007: //// |
| .................... //// * usb_kbhit() moved to device driver. //// |
| .................... //// * USB Token handler changed to workaround a flaw in the USB //// |
| .................... //// peripheral to prevent the USB peripheral from //// |
| .................... //// inadvertantly STALLing the endpoint. Happened most often //// |
| .................... //// in bulk demo applications, especially CDC. //// |
| .................... //// //// |
| .................... //// 11-6-07: Fixed a bug where usb_data_buffer[] was reserving //// |
| .................... //// too much RAM. //// |
| .................... //// USB_MAX_EP0_PACKET_LENGTH value can be overwritten. //// |
| .................... //// For the 18F4450/2450 family this should be 8 //// |
| .................... //// because of limited RAM. Reducing this value //// |
| .................... //// frees RAM for application. //// |
| .................... //// Based upon which endpoints have been configured for //// |
| .................... //// use, will free up unused USB data RAM for //// |
| .................... //// application dynamically. This should free up //// |
| .................... //// at least 128 bytes of RAM. //// |
| .................... //// CDC now fits on a 18F4450/2450 //// |
| .................... //// //// |
| .................... //// 09-19-07: Fixed problems with 18F4450 family. //// |
| .................... //// //// |
| .................... //// 07-17-07: Added 18F4450,2450 support //// |
| .................... //// //// |
| .................... //// 07-13-07: Added 87J50 family support //// |
| .................... //// //// |
| .................... //// 11-01-05: usb_detach(), usb_attach() and usb_init_cs() //// |
| .................... //// changed for the better. //// |
| .................... //// //// |
| .................... //// 10-28-05: Added usb_rx_packet_size() //// |
| .................... //// //// |
| .................... //// 07-13-05: usb_put_packet() changed for 16bit packet sizes //// |
| .................... //// usb_flush_in() changed for 16bit packet sizes //// |
| .................... //// usb_get_packet() changed for 16bit packet sizes //// |
| .................... //// usb_flush_out() changed for 16bit packet sizes //// |

| .................... //// //// |
| .................... //// These are the functions that are meant to be called by the user: //// |
| .................... //// //// |
| .................... //// usb_init() - Initializes the USB stack, the USB peripheral and //// |
| .................... //// attaches the unit to the usb bus. Enables //// |
| .................... //// interrupts. Will wait in an infinite loop until //// |
| .................... //// the device enumerates - if you are using //// |
| .................... //// connection sense or if the processor should run //// |
| .................... //// even if it's not connected to USB then use //// |
| .................... //// usb_init_cs() instead. //// |
| .................... //// //// |
| .................... //// usb_init_cs() - A smaller usb_init(), does not attach unit //// |
| .................... //// to usb bus or enable interrupts. Since this does //// |
| .................... //// not attach to the USB, you must periodically call //// |
| .................... //// usb_task(). See usb_task() for more information. //// |
| .................... //// //// |
| .................... //// usb_task() - If usb_init_cs() was used to initiate the USB //// |
| .................... //// peripheral, usb_task() should then be called periodically //// |
| .................... //// to check the connection sense pin. If the connection //// |
| .................... //// sense pin denotes USB is connected and the USB peripheral //// |
| .................... //// is not attached, this will attach the USB peripheral //// |
| .................... //// so the PC can start the enumeration process (and it //// |
| .................... //// will enable interrupts). If the connection sense pin //// |
| .................... //// denotes USB is not attached and the USB peripheral is //// |
| .................... //// running, this will reset the USB peripheral and wait //// |
| .................... //// for USB to reconnect (and usb_enumerated() will start //// |
| .................... //// returning FALSE). If connection sense (USB_CON_SENSE_PIN) //// |
| .................... //// is not defined the usb_task() assumes that USB is always //// |
| .................... //// connected. //// |
| .................... //// //// |
| .................... //// usb_attached() - Returns TRUE if the device is attached to a //// |
| .................... //// USB cable. A macro that looks at the defined //// |
| .................... //// connection sense pin. If this returns TRUE //// |
| .................... //// it does not mean the PC has connected to it, //// |
| .................... //// you need to use usb_enumerated() to check this. //// |
| .................... //// //// |
| .................... //// usb_enumerated() - Returns TRUE if device has been enumerated //// |
| .................... //// (configured) by host, FALSE if it has not. //// |
| .................... //// Do not try to use the USB peripheral for //// |
| .................... //// sending and receiving packets until you //// |
| .................... //// are enumerated. //// |
| .................... //// //// |
| .................... //// usb_wait_for_enumeration() - Sits in an infinte loop until device //// |
| .................... //// is enumerated. //// |
| .................... //// //// |
| .................... //// usb_tbe(endpoint) - Returns TRUE if the endpoint transmit buffer //// |
| .................... //// is free and ready to accept a new packet for transmission. //// |
| .................... //// //// |
| .................... //// usb_put_packet(endpoint, ptr, len, tgl) - Sends one packet to the //// |
| .................... //// host. If you need to send a message that //// |
| .................... //// spans more than one packet then use //// |
| .................... //// usb_puts(). Fore more detailed documentation //// |
| .................... //// see usb_hw_layer.h //// |
| .................... //// //// |
| .................... //// usb_puts(endpoint, ptr, len, timeout) - Sends a multiple packet //// |
| .................... //// message to the host. If you only need to send one packet, //// |
| .................... //// it is more effecient to use usb_put_packet(). This is //// |
| .................... //// documented in more detail above the prototype in USB.H. //// |
| .................... //// //// |
| .................... //// usb_kbhit(endpoint) - Returns true if OUT endpoint contains data //// |
| .................... //// from host. This will remain TRUE until //// |
| .................... //// usb_put_packet() or usb_flush_out() used. //// |
| .................... //// This function will return an invalid response //// |
| .................... //// if specified endpoint is not enabled for //// |
| .................... //// receiving data. //// |
| .................... //// //// |
| .................... //// len = usb_get_packet(endpoint, ptr, max) - Gets one packet that //// |
| .................... //// from the host/PC. usb_kbhit() must return TRUE before you //// |
| .................... //// call this routine or your data may not be valid. This //// |
| .................... //// only receives one packet, if you are trying to receive a //// |
| .................... //// multi-packet message use usb_gets(). For more detailed //// |
| .................... //// documentation see usb_hw_layer.h. //// |
| .................... //// //// |
| .................... //// len = usb_gets(endpoint, ptr, max, timeout) - Gets multiple //// |
| .................... //// packets from the host, you would use this instead //// |
| .................... //// of usb_get_packet() if you wanted to handle multi-packet //// |
| .................... //// messages. This is documented in more detail above the //// |
