ESPeasy PWM problem

#1 Post by VolkerDU » 09 Feb 2023, 11:57

Hello
I am using WT32 eth-01 board to control my DIY wallbox.
I have configured GPIO32 as PWM output to adjust charging current.

If i send the command "http://192.168.2.58/control?cmd=PWM,32,512" the output PWM is set correctly, but after 10 - 30 seconds, the output resets to off state.

I would expect that the output holds its value as long as there is a new command send to the device.

What can i do to get a permanent PWM signal at the GPIO?

Thanks for your help!
Br Volker

Check if the power source is stable and provides enough voltage to the device. Make sure you are using the latest version of ESPeasy firmware. If the issue still persists, try using an older version of the firmware.

Is there something else using the same GPIO pin?

@bidrohini

I updated the controller from
ESP_Easy_mega_20220328_normal_ESP32_4M316k_ETH
to the latest version
ESP_Easy_mega_20221224_normal_ESP32_4M316k_ETH

Now it works as expected!

Many thanks to all of you!!!
