PWM for Analog strips

[marcobrianza]

Hi have seen that PWM output is possible with a special I2C chip.
Is it also possible using the processor pins?

[MartinMueller2003]

Yes. If you compile with the relay functionality turned in, you can output PWM on a few of the ESPs output pins. Not all platforms support the outputs so you may need to do a custom build.

Thank you Martin, I have seen that on LOIN 32 PRO and also on the wemos D1 mini, the feature is already there in one of the latest CI release (no build required). AWESOME!
On ESP32 the GPIO ID is set to -1 if not configured.
On ESP8266 it starts with 4294967295 (with error indication) see attachment

I guess it is just a type definition error.

Calling the feature Relay is misleading at this point I would call it GPIO.
I immagine that "Trigger Threshold" applies only if PWM is disabled, right?

have a nice weekend.

It is -1 on both builds. When it is -1, the channel is not configured. You need to assign a GPIO. Yes the outputs support both PWM and on/off mode. The trigger point is only valid in on/off mode.
