Hello everybody ! I'm learning PIC16C84 and I've got a simple problem (I think !). I'd like to make a small program which just count down from FFh to 00h by example ! (to wait for the flashing of a led by example...) I think that I will have to use the RAM to do that but I don't know how to do that ! Is there a way to decrement or increment a variable (not a register) ? Thanks. )|( (o o) -----ooO--(_)--Ooo---- Jerome Avot "YOYO" aavot@nordnet.fr
