Hello all,
Two question ¿?
Based on curse 28 Pines (Arduino) I'm designing for PIC.
The PIC 18F26K22 in RB6-PGC (pin27) and RB7-PGD (pin28) ports are pin ICSP but I also want them used for I / O ports.
The question is have to put resistors in series. or as you would have t
o put?
as you do in ATMEGA16U2 / PIN15 (CLK) for ICSP1. (view picture).

Other polemic question is when...
I also want to add on the board an SPI display but this will PIC works 5V and LCD 3.3V, How to connect at different I/O ports (SDI, CLK, SC, A0, RST) if there are differents voltages.

THX.
