pito:
..I would not mess with those HC125 drivers as the 1284p runs fine at 3.3V/16MHz..
Hmm, that's true... I guess I can redesign the board, since I already have 3V reg. I only need 5V to drive LED matrix...
Thanks.
P.S. It seems issue with pin definitions somehow... I tried these bootloaders on same 1284p chip and here's result:
- Mighty 1284 w/ Optiboot: RF12B Module works. SD card doesn't work
- Bobuino: RF12B Module Doesn't work (I know I stated in my OP that it worked, but I was wrong). SD Card Doesn't work
- Sanguino 1284 : RF12B Module doesn't work. SD Card WORKS!
How do I get both working?
