Post: HI Andrew, I hope you are well. Since we last spoke my project is going well but I have come upon a problem of my own making! This is project to create a computer conrolled 42 strong recorder ensemble (remember them from school!). I have 3 IO Pi Plus boards on a Raspberry Pi 4. The outputs from the IO Pi PLus run to Darlington arrays which will drive relays opening valves to allow air into the individual recorders. I strip MIDI files to give me the data to create tunes and then this is fed through to the valves via the IO Pi Plus. This tests well driving LEDs at the moment before building the final recorder organ (Recorgan!) After an SD card corruption I rebuilt the Pi operating system and reinstalled my software. During this process I removed the 3 IO Pi PLus cards on block from the Pi4 and unfortunately replaced them out of line and then powered up. There were pins exposed down the right hand side of the Pi 4. The IO PI Plus cards were moved 2-3mm to the left (looking at the Pi from the USB/ethernet end) Thi Pi 4 seems to be working OK but sudo i2cdetect -y 1 shows the i2c matrix but unpopulated. Is there a way back form this? Regards Tony
