Control circuit and RGB chip are integrated in a package of 5050 components, form a 

complete control of pixel point,has a same outlook  with 5050 LED.

          Signal adopts the single line parallel connection type,any pixels failure won’t effect other

 pixel’s display effect.

          Signal can compatible and expand the DMX512(1990) protocol signal.Data transmission

 speed can be 250Kbps~750Kbps.

          Each pixel’s three primary color can achieve 256  brightness display, completed 16777216 

color full color display, and scan frequency can  be 3000Hz/s. 

         WS2822S is an intelligent control LED light source which combine the control circuit and RGB chip 

together, integrated in a package of 5050 components. Adopts the parallel single wire control signal,owns 

the independent programmable address.WS2822S  has the same  outlook with 5050 RGB LED,each LED is 

one pixel.WS2822S LED has the power supply voltage stabilizing circuit,time base circuit, signal decoder 

block,data buffer,built-in address storage circuit EEPROM.Each pixel owns independent address,any 

pixel’s failure won’t affect any other pixel’s display effect. WS2822S’s data protocol can compatible and

 expand the DMX512(1990)  protocol signal.Data transmission speed can be 250Kbps~750Kbps.WS2822S

 has the independent write code signal line,the address can be written in series at one

One entire data package consists of several data frames, each frame of data including 1 low start bit, 8
data bits, 2 stop bit high level. Control data is 8 bits, the level combinations from 00000000 to
11111111,total of 256 state (corresponding decimal number 0 ~ 255), control the brightness of light, can
produce 256 brightness levels, 00000000 (0) corresponding to light the darkest, 11111111 (255)
corresponding to the brightest lights. Packet first frames, lamps and lanterns corresponding to the first
channel, second frames corresponding to the second channel lamp, and so on, 512nd frames
corresponding to the 512nd channel lamp, lamp channel address can be set on the lamp.
One entire data package consists of one MTBP bit,one Break bit,one MAB bit,one SC(start code,means
start code frame) and some data frame,MFBF bit means time interval between frames to be a high level
range is 0~1 seconds.
MTBP(Mark Time Between Packets) stands for after sending one entire data package,it will be the
“vacant” bit for next data package’s start,high voltage is effective.Break is interrupt,corresponding to a
packet program reset stage after one package is over,width is no less than two frames (22bit) time.
After program reset,it will have a high level pulse MAB(Mark After Break) which have function of
interval, separating function,once the pulse arrival,it means effective control data frame begin.
Each data frame consists of 11 data bits, the first bit (the start bit) is a low level, the middle 8 bits are with
information data, high level is 1 code, low level code is 0 code, 10th and 11th bit data is the end bit with a
high level.
Start code frame is the same with data frame later arrival, is composed of 11 bits, in addition to the two
high level at the end position, the other 9 bits are all low level, usually known as the zeroth frame or
zeroth channel (CHANNEL0), can be understood as an absence channel. Each data frame includes a 1 bit
low level start bit, 8 data bits and 2 bits high level stop bit. Information data of 8 bits is low first, its level
combinations from 00000000 to 11111111, totally have 256 states (corresponding to decimal number 0 ~
255), during control the light brightness,it can produce 256 brightness levels, 00000000 (0) corresponding
to light darkest, 11111111 (255) corresponding to the light brightest. In each data package,first frames
corresponding to the first channel’s lamp,second frames corresponding to the second channel’s lamp, and
so on,3072nd frames corresponding to the 3072nd channel’s lamp,the lamp channel’s address can be set
on the lamp,fixture channel address can be arranged in the lamp. This protocol is extended on the basis of
the DMX512 protocol, the data rate range is 200KHZ to 750KHZ, the data frame contained in each
package can be 3072 frames.

Write address code data format
Use a similar gray control data protocol, frequency is 250kHz. Channel data package maximum has 3072
frames, when sending data usually high bit comes first. Each time you can send a data package for one
time. Data package must be high level before and after sending the data package, before sending the
data ,must have a above 5ms low level. Specific rules are listed in the following table:
