Programming Failure
PostPosted: Tue Feb 07, 2006 7:30 pm     Reply with quote

I'm prototyping with a 18f452 on a solderless breadboard, but the ICD2 never recognizes the PIC chip("cannot validate target device") when I try to program the PIC.

ICD2 passes the self test, I'm providing power to all of the Gnd/Vdd pins, and I've provided an external clock source of 4MHz through a function generator.

Are there any gotchas you guys can think of? Any help is greatly appreciated.
