Goodmornig everyone.
In order to expand the Arduino input capability I built a simple INPUT board that collects all the signals coming from a bunch of HALL sensors using the IC 74HC165...
The 74HC165s are all daisy-chained on the board...
Sometime I miss some of the sensors signal and, in order to troubleshoot the problem, I have to test each HC165 removing them from the board and using a simple test jig I built for this pourpose...
The test is done ONE BY ONE!
The problem is that this procedure is a waste of time and I was looking for something that can allow me to test the HC165 in place and then replacing the dead ones...
Can someone point me in the right direction?
Thanks in advance
