First program works! In a cycle I'm doing ADD+ADA operations on 25Hz!
1: ADA+0xFF00 - set Address register to 0xFF00
2: ADD+1 //increment value in current memory cell
3: ADA+1 //shift current memory cell number
//repeate last two instruction 16 times, because writing inner loops in brainfuck is brainfuck enough :)
33: ADA-0xF //return AP to 0xFF00 memory cell
34: JNZ-0x21//if current cell is Not Zero, return IP to number 1 (which would be skipped due to pc arch).
All instructions are repeated.
