The first pc shows my test jig/setup. I ran it for almost 2 weeks non-stop without any problems.
The next picture shows the electronic package installed—this is where I ran into a problem. The interrupt (the white wires) is getting falsely triggered. Telling me that it is getting triggered by noise coming off the other wires. What is strange when I attached my DVM to the interrupt test point, every started working properly and without any false interrupts!! This is telling me I need something to cancel out noise, like the DMV is doing.
The last picture is a screenshot of the PCB with the interrupt trace highlighted
.
So this all boils down to a possible cap (or something else) to cancel out the noise.
I am asking what type and value of cap would work/
