[Fx2lib-devel] Firmware Frameworks and IIC generation

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

The examples in the fx2lib directory are fine and dandy for learning and 
getting started, but there is still quite a lot of code to get together 
when writing a real firmware.  I decided to go the same route the 
Cypress did with their Keil Uv2 frameworks and provide a framework 
example that one can easily extend to build their own firmware.

Today I committed a new directory: fx2lib/fw.  Therein, you'll find 
fw.c, which shouldn't need modification and device.c, which you add your 
own code to.  dscr.a51, which all you may or may not need to customize 
to get your own USB descriptors.

Features: 
 Sleep, Resume
 USB commands (config descritors, get/set feature etc)
 Easily add your own vendor commands.
 
I also added a python script for generating iic files for loading on 
eeprom images.  I originally borrowed the script from gnuradio but then 
enhanced it to be generic for any ihx file and also to compress the iic 
output the same way the Cypress utility does it.  (This makes a big 
difference if you want to fit your image on a smaller prom!).

Anyhow, enjoy.  I committed a number of other enhancements and minor 
changes in the last few days too.  You can look at the changelog on github:
