Driving WS2811 with Signal Generator


#1

Is it possible to drive a chain of WS2811 (say 16 of them) using Signal Generator? I’m thinking all I’d have to do is set the frequency and provide the obligatory array of zeros and ones.


#2

I think the community had used these LEDs successfully using SPI. There is a tick to precalculate the needed date on mosi pin. SCK is ignored and not used.


#3

Yes, I know they did, but I’m just about fresh out of SPI buses on my G120. (one use used by an ENC, one is used by the L6480s)


#4

Add an AND gate to the led and put it on an existing bus


#5

Like @Justin suggested. You can theoretically add unlimited devices on SPI, each with its own chip select. If your slave doesn’t have a chip select, then add an AND gate.


#6

Alright, I’ll try the AND gate.
