Aurelio designed me a transistor circuit so I can use the volume - button to switch 3.3v. I didnt want to have a dedicated sync button and leaving it out felt wrong so this was the best solution. The schematic is posted in the worklog.Volume is usually controlled by GND but Sync uses 3.3v, so I'd like to know, how did you put them both in one button?
