so this is my preparation:
1: i need to print pcb using this one.
viewtopic.php?f=3&t=1623 (i will use 644 with 56 ins)
2. Order the parts online
3. solder everything
4. hooked isp cable
5. program using the latest unencrypted firmware
6. tweak
7. and play drums using diy pad.
are these steps correct?
so the pic18f2550 and the 6n138 are important when using the unencrypted firmware?
