Change signal timings for other protocol

[ScobbyDoo]

1:-Right now on ws 2811 works fine, i need to change signal timings th0 tl0 th1 tl1 according other chipset.

2:- Even more ,how to assign DMX signal timings for output instead of ws2811 protocol timings.

I want to understand you want the i2s to output dmx data following the dmx protocol. ?

[ScobbyDoo]

Yes

Is their any timer calculation available foe that?

It’s totally feasible but the buffer need to be reversed and the led signal is 3 ´ticks’ for one bit and here one tuck per bit

Reversing buffer ,may be i can manage, But what about ticks? 2811 needs 24 bit shifting & dmx dont support that

Hello For the leds if you want to send a 0 you need to send 1 for a certain period of time and then 0 for another And the difference between 0 and 1 is the duration of the 0 and the 1. That is the reason TH and TL. For simplicity and efficient the timing of the 2811 and 2812 is split in three ticks. To send a 0 I need to send a 1,0,0 and to send a 1 I need to send 1,1,0. Of course as for the ws2812 the bit timing is 800khz the tick frequency is 2.4mhz. if you want to send dmx like you need to take the code of the apa102. As for these if you want to send 1 you just send 1. I hope I was clear

Here is timing for fastled Where do i found in clockless library to Change timing?

I will test and add pull request for custom chipset same as fastled
