Doing a RGBW lamp, White channel PWM ?
Posted: Thu Feb 07, 2019 3:25 am
just wanted to know what is the right way of doing a RGBW lamp:
https://hackaday.io/project/163672-esp3 ... led-panels
Started a project in Hackaday to make your own ESP-Mesh lamp and I'm using just the RGB PWM outputs. I though it would be possible to combine all Red, Green and Blue to make white, but I think white has it's own channel right :
```
11 | GPIO23 | O | PWM_BR output control
12 | GPIO19 | O | PWM_CT output control
```
My question is, should white be connected to GPIO19 ? Or what would be the best option to modify this and make it work with normal RGB Leds ?
Sorry if it's not such an interesting question, I wanted to create a project so electronic fans can create their own RGB Lamps with things that are already somewhere in their garage
Also last question, what is the default PWM frequency in the Light example ?
I guess it's possible to configure it editing the code. Thanks in advance
