Hi.

I wrote code for WS2822.
https://youtu.be/rwB2WzpK9CQ

1)Setting address
Addr_struct 1 addr LEDs setAddr
This word set address to LED(2pcs).
When setting is successfull, LED's RGB-LED is on.
To escape addres-setting mode, power must be off.
LED(L)on board firstly is set to cannel-4.
LED(R)on board secondly is set to cannel-7.

Signal   1bit=4usec
MTBP:88usec
BREAK:5msec
MAB:88usec
SC:0[8bit]
channel number:4[8bit]  (When address is 1, channel is 4)
channel data 2nd:hFO[8bit]  (channel= 1 to 255)
channel daa 3rd:hD2[8bit]
channel number:7[8bit]  
channel data 2nd:hFO[8bit]  (channel= 1 to 255)
channel daa 3rd:hD2[8bit]
Sending 8bit: startbit[1bit]+data[8bit]+stopbit[2bit]

2)Running
c" WS2822 buf_size data a_sendData" 0 cogx  
Sending 8bit data to address[0 - 1023],channel[1 - 3072].

Signal   1bit=4usec
MTBP:88usec
BREAK:88use
MAB:8usec
SC:startbit[1bit] 0[8bit] stopbit[2bit]
data[8bit] from buffer
next data[8bit] from buffer[Blue]
next data[8bit] from buffer[Green]
next data[8bit] from buffer[red]
next data[8bit] from buffer[Blue]
next data[8bit] from buffer[Green]
next data[8bit] from buffer[red]
..
last data[8bit] from buffer
Return MTBT

Sending 8bit: startbit[1bit]+data[8bit]+stopbit[2bit]

I tested from address 0 to address84.
It operated finly.
But it was strange from address 85 to address170.
2 LED should be series address(channnel).
But it was NOT.
LED vs buffer were strange.
It should be wrong channel 2nd data or channel 3rd data bor my assembler code.
I have no idea.

Not tested more than addres171(channnel512).
