Hi all, I have an ICSP question I hope someone can shed some light on. I am using the ICSP connector on my Warp13 programmer with a 16F84, and I find that the Warp software reports multiple errors if the +5V to the PIC comes from my circuit. If I disconnect my circuit +5V and power the PIC from the programmer, the chip programs fine, but I can't execute the program until I switch the +5V back to the circuit supply. (MCLR is isolated with a diode and a resistor.) I can live with this if I have to, but if there is any way to avoid the repetitive shifting of the +5V supply back and forth, it would certainly simplify things. Any suggestions? Thanks...
