Thank you! It's coming along well. I ran into a strange issue today. I connected a 4-20ma sensor to the board and something strange happened. Now, this is probably induced by some sort of over voltage to the adc pin or something nasty going on, but after this event happened, the adc measurements froze (subsequent reads from the adc return the exact same number). So I tried restarting my program and it would hang on pruio_config(). I tried restarting libpruio-lkm.service with no luck. I think a big clue as to what happened is the fact that the heartbeat led stopped flashing. Eventually I power cycled the board and everything returned to normal. It seems like the pru's locked up (probably in response to an over-volt situation on an analog input)
