So I have two programs that are mean't to talk to radio's via GPIO pins but need them to talk to each other via GPIO

Eg..

Program 1 PTT = 12 COS = 16

Program 2 PTT = 16 COS = 12

So basicly when Program 1 keys up its sets Pin 12 high then Program 2 see's pin 12 is high and triggers it.

I get an error saying the device is busy tho when I do it like this.

Any other ideas as they both talk on GPIO pins

Thanks Sonic
