Notes On Integrating AVRUSB with Arduino
|
|
========================================
|
|
|
|
* Note the license(s) under which AVRUSB is distributed.
|
|
|
|
* See also: http://code.rancidbacon.com/ProjectLogArduinoUSB
|
|
|
|
* Note: The pins we use on the PCB (not protoboard) hardware shield are:
|
|
|
|
INT0 == PD2 == IC Pin 4 == Arduino Digital Pin 2 == D+
|
|
|
|
---- == PD4 == -------- == Arduino Digital Pin 4 == D-
|
|
|
|
---- == PD5 == -------- == Arduino Digital Pin 5 == pull-up
|
|
|
|
(DONE: Change to not use PD3 so INT1 is left free?)
|
|
|
|
* In order to compile a valid 'usbconfig.h' file must exit. The content of this
|
|
file will vary depending on whether the device is a generic USB device,
|
|
generic HID device or specific class of HID device for example.
|
|
|
|
The file 'usbconfig-prototype.h' can be used as a starting point, however
|
|
it might be easier to use the 'usbconfig.h' from one of the example projects.
|
|
|
|
TODO: Specify the settings that need to be changed to match the shield
|
|
design we use.
|
|
|
|
* (NOTE: Initial 'usbconfig.h' used will be based on the file from
|
|
'HIDKeys.2007-03-29'.) (Note: Have now upgraded to V-USB 2009-08-22.)
|
|
|
|
* At present the IDE won't compile our library so it needs to be pre-compiled
|
|
with:
|
|
|
|
avr-g++ -Wall -Os -I. -DF_CPU=16000000 -mmcu=atmega168 -c usbdrvasm.S -c usbdrv.c
