Hello
I'm not sure where else to ask this question as it's not a Moode problem.
I have a PI 3B (running latest Moode) connected to an old NAD amplifier via a USB DAC. The pi has, connected via GPIO, an Adafruit OLED screen (SPI) and a on/off button that includes an LED.
LED setup - https://howchoo.com/g/ytzjyzy4m2e/build-...-indicator
Button setup - https://howchoo.com/g/mwnlytk3zmm/how-to...spberry-pi
My problem is that the amp turns the pi on/ off. I turn the amp on the pi turns off. I turn the amp off the pi turns on. I think the pi is receiving a power spike from the amp.
I cant figure this out. I think the pi and/ or the DAC is 'floating' but i don't know how to weigh them down.
Any help with this would be much appreciated.
Thank you
Paul
