Re: [Fx2lib-devel] Allmybrain.com Question/Comment: EZ-USB FX2

[Dennis M. <de...@ub...>]

I don't currently have any windows specific downloads, but the fx2lib 
code can be compiled with sdcc on windows.  The utilities are written in 
Python, which can also be run on Windows.  The only problem you'd have 
is the fx2 driver, which currently uses libusb-1.0, and there isn't a 
port of that on Windows.  For my own projects, I use libusb-0.1 on 
windows.  I'd like to provide a more robust windows interface for fx2lib 
but that is still slated for the future some time.  You should, in the 
mean time, be able to use the cypress utilities on windows to load your 
firmware though.

Most of the examples in fx2lib use printf for debugging.  You can see 
the output of those statements if you have a serial console and attach 
to the sio-0 port on the dev board at 57600 baud.  That is how I 
debugged and got most of fx2lib working correctly.
