Hello Everypne
Just a quick one, I need to use the ICSP pins for other things in my circuit. I know I need to try and isloate them. In the circuit I have a comparitor from a LM324QT opamp. Do you think it would be OK to just stick a 10K resistor between the comparitor and PIC so that there is nothing between the ICSP pins and the PIC?
Thanks

Re: ICSP islotation
Hi,
That is exactly what i do, use a 10k resistor to isolate external components, e.g POT's.
Of course will not be much good at low resistance sourcing and sinking, so can't power LEDs direct.
I also use a 10K from MCLR to VDD if MCLR is required.
If using a capacitor from MCLR to ground, then I would use an additional resistor from the cap to MCLR pin of about 470R.
