GPIO Settings - Enabling GPIO handler

[wokkeltje13]

I want to use external leds but the moment I enable "GPIO Settings - Enabling GPIO handler" no led is working, even if I select to use GPIO4 (built in led) this is not working. When I disable GPIO settings, the interna led is working correctly.

Am I doing something wrong? or is this an issue?

forgot to mention, I am using latest build: master - v10.5.2

The settings for 2 external WS2812 LEDs looks like the following:

It is working on 3 devices w/o any problems.

This is how I tested

, but the leds are not working, even just enabling GPIO4 does not work with only the build in led.

I assume you have connected the WS2812 to GPIO12. Then I assume a hardware failure. With this setting my systems are working without any problems.

[wokkeltje13]

but should this config not just work with the build in led? Same as without the GPIO settings enabled.

[jomjol]

It should work, but there is no reason to use this. The normal setting is okay for this. Therefore I have not testet it.

[wokkeltje13]

as a troubleshooting step, I tried the GPIO4 way to be sure and this is also not working. So I was thinking something is wrong in my config.

I had the same issue.

I guess it was because I have edited the configuration in expert mode, and saved it. When you edit the configuration the first time, PWM duty resolution entry is blank. May be a wrong value is written in config.ini.

I have manually entered 8 as PWM duty resolution, and that made the external LEDs work.

tnx, the PWM value did the trick.
For other users it would probably be nice if this value had a correct default value or if you could see this value in the normal config window (without the need for advance config)

Oh my goodness, that made my day!
Thank you so much @EmmanuelP for the hint to the PWM Value, and thanks @wokkeltje13 for asking the question!
Since about 4 weeks i was searching for a reason, why the external LEDs stopped working, even after exchange of the LEDs and the ESPCam, but using the same SD-card :)

Create, that you found the topic. The default value is "10". I just tested different savings and configurations, but could not reproduce this problem. Maybe a manual change for some unkonw reason. I close this issue.
