I want to add ICSP support on Nigel's tutorial development boards.
I need to isolate the circuit from Vpp with a diode. Is there an alternative to a schottky diode that will apply 5V to MCLR to enable the target PIC?
I'd really like to not lose RB6 & RB7 to ICSP. Can I use a similar technique with 2 diodes connected to each pin with opposite polarities to allow ICSP *and* I/O on RB6/PGC & RB7/PGD, or would this mess the programming signals too much?
The ICSP guide from Microchip doesn't give much details on this...
