[Fx2lib-devel] GPIF conversion script

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

I just pushed a script that converts the gpif designer output to a state 
usable by sdcc and the fx2lib library functions.

fx2lib/utils/gpif2dat

usage:
 gpif2dat <gpif designer exported c> <save file name>

example:
  gpif2dat gpif.c gpif_dat.c

Create a rel file from the data file:
 sdcc -c gpif_dat.c
Then, in your firmware, you can make reference to the variables:
 extern const char WaveData[];
 etc.
And use the gpif functions from fx2lib
gpif_init(WaveData,InitData);

And then compile your firmware
 sdcc firmware.c gpif_dat.rel


I haven't yet added a gpif example to fx2lib yet because I haven't 
thought of a good example to add.  The ez-usb development board doesn't 
have a device connected to the gpif and everyone elses boards have 
extremely custom gpif waveforms.

Hope this makes things more convenient though.  I use these commands 
within a makefile so that I don't have to do anything manually after I 
export the gpif code from the designer.

Just a side note:  the gpif designer works very well under Wine on Linux.
