I am considering creating an arduino based cable scan tester that can test up to 100 lines by first learning a good cable
and then testing subsequent cables. This will require sending data patterns across all 100 lines and reading them
back at the other end of the cable.
I am not sure what the best way to read and write up to 100 lines and could use some recommendations of what
parts external to the arduino would be best to use.
Can anyone suggest the best way (with the least amount of parts) to be able to read & write to 100 lines with an arduino?
thank you
