Was using pins 5,6 & 7 for the switching so tested with pin 20 (not used previously) SetPin 20 dout.........0V Pin(20)=1 .............3V3 Pin(20)=0 .............0V SetPin 20 din .........0.5V All measured to Analog GND No circuitry attached to Pin 20 Similar results to Phil99   Quote   Are you certain the diode is cathode to +? I am using a schottky diode and the anode is definitely to 3V3. OA47
