Pwm problem on pins
Posted: Mon Jan 03, 2022 11:06 am
Hello everyone,
I am generating pwm over esp32 for high voltage source. The circuit works, but I get signals from other pins except the pin (22) where I get the pwm signal. Although I pull the pins low, I can get high voltage values when I look at the other pins except the 22nd pin. Is there any suggestion?
