* Some interferrences with the two timers (usb/led) * Big cleanup from the codebase and separate logical parts * Documenting the code * Big space optimizations on the code to fit on the AVR

This example should run on most AVRs with only little changes. No special

|
hardware resources except INT0 are used. You may have to change usbconfig.h for
|
|
different I/O pins for USB. Please note that USB D+ must be the INT0 pin, or
|
|
at least be connected to INT0 as well.
|
|
We assume that an LED is connected to port B bit 0. If you connect it to a
|
|
different port or bit, change the macros below:
