At end of every semester or camp I want to test my sets of various Parallax boards. Anyone have an idea for hardware and code so I can slap a shield on a board, run a progam and get a report by DEBUG or serial.out? At minimum would be pins (even if just light-up, not report to serial). Good to add function of ADC, DAC, supply voltage, memory, anything else that might be broken by students.
I am thinking there must be something like this already used by Parallax to test at end of production.
What I want wouldn't have to be a production product, I can solder up the hardware if I have a schematic / wiring diagram using this:
Here is a start point for code.
