By the way, the famous Jan Axelson from www.Lvr.com has adapted
Brad Minch's lab 2 (keyboard) code to a generic HID class firmware
(with MPASM) and it can be downloaded from Brad Minch's class
website as well. In the main program, she has shown example
to copy the EP1 OUT data (from PC) to EP1 IN (to PC) buffer
using interrupt transfer. This code should be easy to be
adapted to gpasm now than Ben has worked out the macros
for gpasm.
Jan Axelson has also adapted Microchip's HID mouse example to
a generic HID example. The code is using MPLAB C18 though.
The code can be downloaded from her website. In the example,
interrupt IN and interrupt OUT are both implemented.
