Re: usb_8dev: firmware and windows library

[Bernd Krumboeck <krumboeck@universalnet.at>]

I've created a new branch for tests with GNU toolchain.

https://github.com/krumboeck/usb2can_firmware/tree/gcc-test


The code should compile and create a main.bin file.


Missing things:
* Tests on hardware
* Generate CRC16 and replace the last 2 bytes of main.bin


regards,
Bernd
