Newbie question... why dont this work...??
Hi all,
sorry if I appear to be a thicko newbie, but last week I bought Proton from Crownhill, and I am having a slight (?) headach trying to get my code to work!
For a project I am trying to get an RF module to run three very simple output routines.. flash led, make a sound, do both, etc...
I am using a 12f629, the code seems to compile ok, with no errors, but no matter what I try, the routines always seem to get stuck in a repeating loop. They never break out, or return to their respective gosub calls.. the chip is being programmed / erased with a PicKit1 doofer... Eventually I want to use the rfPIC12F675f
I know I am doing something REALLY stupid, but any comments would be a help.. and I'd like to get this sorted before I commit to making some pcb's!
Cheers in advance,
Shax.
