How did you make this bin file?

If I were you I would make a PC program to decode and write out the file as 8bit values ready to be sent to glcd_ functions. I wrote a perl program to do something like this it could be changed to write out a file on the PC that could be read by the MMC/FAT driver function fatgetc().

The problem with my perl code is it assumes a lot about the format of the bitmap 256x128 1 BitsPerPixel.

Will post if you think it will be helpful.

Do you have the CCS MMC/FAT code working?
