Feb 16, 2020 at 19:28 comment added George To improve, maybe checking if the process is alive, then checking if the wave signal is high takes too long and maybe an event of when it's high that triggers the adc reads is more efficient.
Feb 16, 2020 at 19:18 comment added George Just added the code
Feb 16, 2020 at 18:22 comment added joan What code are you using? Perhaps add a short script which shows the problem.
Feb 16, 2020 at 17:19 comment added George I meant to read, while it's generating the PWM at the same time, i.e while it's outputing the PWM signal, I can read if it's high or low.
Feb 16, 2020 at 17:19 comment added George that's weird, when I tried to do a read() it stopped the PWM functionality.
Feb 16, 2020 at 8:45 comment added joan If you are using pigpio you can read any GPIO regardless of its mode. Just call the read() function. There is no need to set the GPIO as an input (because if you do so that stops the GPIO acting as an output).
