What the heck is a “PIC24F675”???

There’s no way that this code could be successfully assembling at all - for example, you’ve got “BCF STSTUS,PRO” instead of “BCF STATUS,RP0”, and a couple of undeclared variables in your delay routine.

leon_heller · October 6, 2007, 3:54pm

He means PIC12F675, which he has at the beginning of the code. The listing is completely incomprehensible, anyway.
