AVR GCC development environment test software.
See the following article for details:
http://main.linuxfocus.org/English/November2004/article352.shtml
 
To compile type the command:
make
 
Note: You will get some warnings "#warning "This header file is obsolete."
during compilation with avr-libc-1.4.X. This is because this code will
also work with avr-libc-1.2.X
 
Alternative 1: Programming with uisp (dapa programmer):
-------------------------------------------------------
Make sure that you have loaded the following modules in the kernel (for 2.4.x)
before you use the uisp programmer:
> /sbin/lsmod
Module Size Used by
parport_pc 17808 0
ppdev 5312 0 (unused)
parport 25856 0 [parport_pc ppdev]
 
 
To compile and load use:
make loaduisp
 
Alternative 2: Programming with avrusb500 (high speed usb programmer from tuxgraphics):
---------------------------------------------------------------------------------------
Make sure that you have loaded the following modules in the kernel
before you use the uisp programmer:
> /sbin/lsmod
Module Size Used by
ftdi_sio 20568 0
usbcore 57792 1 [ftdi_sio usbserial]
 
 
To compile and load use:
make load
 
Files:
------
avrm8ledtest.c # the c source code for ATmega8
avrm8ledtest_pre.hex # pre-compiled loadable object in case you have
# trouble to compile the software

-------------------------------------------
History:
version 0.1: 2004-10-01, first Version
version 0.2: 2004-12-30, corrected fault in delay_ms function
version 0.3: 2005-10-04, new modular programming with the scripts prg_load_uc
and prg_fusebit_uc for easy transition to the new
avrusb500 programmer
version 0.4: 2006-03-02, compiler independent delay loop. The old delay_ms
would behave totally different with the new gcc-4
version.
version 0.5: 2006-03-10, Fault in delay_ms corrected
