Just ported some ASM code projects from old micro where I used only few I/O. Here is a list of changes - -Replace PORT(A or B) with GPIO -Replace TRIS(A or B) with TRISIO - GPR start from 0x20. So if u define CBLOCK 0x0C etc change it to 0x20 - set Reg CMCON in bank0 for digital IO - Move EEDATA, EEADR to bank1 Tom

My new media player needs about 8 key presses to skip over TV commercial breaks and then another 6 or more to backtrack if I overrun. I'll have to knock up a tailor made controller with all the required button presses pre-sequenced to avoid the tedium of all that button pressing. I already have some 16F84 12 button IR remotes left over from an ancient project which I can get going if I can find...
