No. Option List is empty.
Some more info. I think I've narrowed it down.
Apply Setpin DOUT only for relay outputs 1-4, IR code received OK
Apply Setpin DOUT only for relay outputs 1-5, IR code NOT received.
Apply Setpin DOUT only for relay outputs 6-24, IR code received OK
So Relay 5 output is the culprit.
Another observation: Output 5 outputs 3.3V on powerup. However, when made a DOUT on its own, the 3.3V disappears and the pin behaves normally when set to logic 1 or 0. This could be a defect. I have another Pico with the same Output 5 (GP3) doing the same thing.
Will try to reorganise pin allocations to get it working or get a new Pico.
Thanks everyone for nudging me towards a solution.
