Which is more or less the same as: https://blakadder.github.io/templates/q ... immer.html
It works fine, but when I enable input (I tried gpio5 and gpio13 which I need), I get a very high packet loss.
Also with INPUT_PULLUP the packet loss is very high.
When I tie the inputs to gnd, the packet loss is 0.
Why do I get packet loss when I configure these pins as input?
I also had to set GPIO to output, otherwise the same packet loss occurs.
When I measure the pins with a 20mhz scope, I don't see any noise.
