Hello,  
i get my TLC5947 running on the Wemos D1 mini - it is able to drive 24 discrete PWMs/Leds.  
Now i want to use it together with wled.  
I want to use them to light up some lego models - together with the WS2812b  
What would be the right approach?  
I thought of implement them within a own segment and special effects, which has to be selected with this segment(s). The brightness can be used from the master-slider.  
Other idea: extend the amount of leds within the ws2812b-strip an read out the values cyclic to put use them within the TLC5947  
Any other solution?  
Any hints will be helpful…

Hi there,

I also have a setup with 13 PWM-LED strips that are RGB and therefore require 39 PWM outputs.

For this I use two [TLC5947 boards from adafruit](https://www.adafruit.com/product/1429). These boards can be chained.

However, I use raw Arduino Code which does work, but effects have to be integrated … In short it was great if wled could just control those PWM drover boards.

Any progress on that 4 years after the OP?

Use WS2811 external chip, it is well supported and since 0.16 can be used as individually addressable white only.
