Hello Iwindridge,

IWR>>What I appear to have a problem with though is the interrupt interferes with the serial input and seems to knock it totally off timing.

Does anyone have any other suggestions for reading the data from the master PIC which is a little more interrupt friendly (I've tried using shiftin and shiftout but with little success)?<<

Make sure you turn off your interupt when you branch to your routine.. with disable command., or you will interupt again.


Can you post some barebone code for us to look at?


Also, I while back, I posted some code for 2 pin and 1 pin communication between two chips. Granted, it is not using PBP SERin or other commands of commuication, it you want me to, I will look up the code for you.
