Connect two PICs?
I have a situation where I need to connect two PICs. One is the 'master' and one is the slave. An output on the master goes to an input on the slave (weak pull-up enabled) and I only need to signal two states.
My question is: Do I need a current limiting resistor on that line? I keep vacillating between the two answers, and thought I'd ask the experts.
Thanks,
Andy
