*****************************************************************************
|

** ChibiOS/RT port for Atmel AVR AT90USB128. **
|
||||
*****************************************************************************
|
||||
|
||||
** TARGET **
|
||||
|
||||
The demo runs on an PJRC Teensy 2++ board.
|
||||
|
||||
** The Demo **
|
||||
|
||||
The demo creates a standard serial-over-USB (CDC) slave device. The simple
|
||||
ChibiOS shell is run on the USB serial connection and can be interacted
|
||||
with by a standard serial port program (e.g. putty or screen).
|
||||
|
||||
** Build Procedure **
|
||||
|
||||
The demo was built using the GCC AVR toolchain. It should build with WinAVR too!
|
||||
|
||||
** Notes **
|
||||
|
||||
The USB driver itself is not that heavyweight but this demo requires a bit of
|
||||
flash space and memory because of the nature of the ChibiOS shell code and
|
||||
supporting functionality.
