pito:
You may enhance your Cosa mcu collection with atmega32 (same pin layout as the 1284p, bootloader works, the core and variant of the mighty1284p works under 1.5.2.).
I will see if I get the time for this later this week. Dont like the idea of doing too many modifications I cant run through the tests. Thanks for the schematics. Will need to read up on the spec as well.
Cheers.
