Just in testing phase of my setup. Everything works perfectly direct to mega also with one mux board no problem input and output. When I try to connect 2 or more boards things go crazy. Pins stop working, parameters cross over - ie. pin 6 will become pin 3 or come on together. Alot of interference. Setup is on breadboards with a mess of wires together in close proximity. Could this be just electrical noise causing interference??
Also on configurator I cannot setup rotary encoder to allow input state for pushbutton - ie, to change between mhz and khz. I hit conditions then Input On - then I cannot select a pin. This was working a week ago but last few days nothing.
Your help much appreciated
