Hello all,
Included is the circuit I have connected to a micro controller. This works great, if I have the pins connected 1:1, also it correctly detects if I disconnect a pin or swap pins.
What i'm having trouble with is if I short pins together, i.e. rather than pin 1 on output connected to 1 on the input and 2 output connected to 2 input, having pin 1 output connected to both 1 and 2 input, and 2 still also connected to 2. I get mixed results, some times its correct and shows the short, but it also can show as if its connected 1:1 or any thing in between.
Any pointers what I can do to theis to correct it, im pretty sure its in my curcuit not the code running on my micro-controller.
Thanks
Sol
