I am trying to get a sanguinololu running for a friend, but am getting readings from the thermistors of 220 degrees plus even without a thermistor being connected.
Diagnostics that I have carried out:
Check voltage at thermistor pins (33 & 34) on Atmega MCU, 0.24V & 0.55V
Removed MCU and checked voltage at same pins on MCU socket, both 5.00V
Checked software configuration.h. Board 62 (sanguinololu) selected and thermistors correct,
Checked software pins.h - pins appear correct.
Is there anything else on the hardware or software that could cause this before I tell him that the MCU needs replacing?
Mike
