Did You read this Bill ?j1sys said:well, you can take the WS2811 to +99%. I played with some this afternoon and they appear to work fine on the TM180X protocol at 2400kbps.
Technically the TM180X protocol is a 1:2 vs 2:1 (total 3 time periods) ratio. that doesn't match the specs for the WS2811 but it seems to work fine.
I'm going to implement a 1:3 vs 3:1 (total 4 time periods) ratio. It is still not match the spec but I bet it will work very well with the WS2811 and may even be the newer standard for the TM180X. I will leave TM180X at 1:2/2:1 and do WS2811 at 1:3/3:1. then people can play. if we need to go to 1:4/3:2 (which is closest to the spec) then we can, but I don't think it will be necessary.
