||
4 | Dependencies: See INCLUDES section |
||
5 | Processor: PIC18 or PIC24 USB Microcontrollers |
||
6 | Hardware: The code is natively intended to be used on the following |
||
7 | hardware platforms: PICDEM FS USB Demo Board, |
||
8 | PIC18F87J50 FS USB Plug-In Module, or |
||
9 | Explorer 16 + PIC24 USB PIM. The firmware may be |
||
10 | modified for use on other USB platforms by editing the |
||
11 | HardwareProfile.h file. |
||
12 | Complier: Microchip C18 (for PIC18) or C30 (for PIC24) |

17 | The software supplied herewith by Microchip Technology Incorporated |

18 | (the Company) for its PIC® Microcontroller is intended and |

19 | supplied to you, the Companys customer, for use solely and |

20 | exclusively on Microchip PIC Microcontroller products. The |

35 | Summary: |
||
36 | This file contains all of functions, macros, definitions, variables, |
||
37 | datatypes, etc. that are required for usage with vendor class function |
||
38 | drivers. This file should be included in projects that use vendor class |
||
39 | \function drivers. This file should also be included into the |
||
40 | usb_descriptors.c file and any other user file that requires access to |
||
41 | vendor class interfaces. |
||
42 | |||
43 | |||
44 | |||
45 | This file is located in the "\<Install |
||
46 | Directory\>\\Microchip\\Include\\USB" directory. |
||
47 | Description: |
||
48 | USB Vender Class Custom Driver File |
||
49 | |||
50 | This file contains all of functions, macros, definitions, variables, |
||
51 | datatypes, etc. that are required for usage with vendor class function |
||
52 | drivers. This file should be included in projects that use vendor class |
||
53 | \function drivers. This file should also be included into the |
||
54 | usb_descriptors.c file and any other user file that requires access to |
||
55 | vendor class interfaces. |
||
56 | |||
57 | This file is located in the "\<Install |
||
58 | Directory\>\\Microchip\\Include\\USB" directory. |
||
59 | |||
60 | When including this file in a new project, this file can either be |
||
61 | referenced from the directory in which it was installed or copied |
||
62 | directly into the user application folder. If the first method is |
||
63 | chosen to keep the file located in the folder in which it is installed |
||
64 | then include paths need to be added so that the library and the |
||
65 | application both know where to reference each others files. If the |
||
66 | application folder is located in the same folder as the Microchip |
||
67 | folder (like the current demo folders), then the following include |
||
68 | paths need to be added to the application's project: |
||
69 | |||
70 | . |
||
71 | ..\\..\\Microchip\\Include |
||
72 | |||
73 | If a different directory structure is used, modify the paths as |
||
74 | required. An example using absolute paths instead of relative paths |
||
75 | would be the following: |
||
76 | |||
77 | C:\\Microchip Solutions\\Microchip\\Include |
||
78 | |||
79 | C:\\Microchip Solutions\\My Demo Application |
