描述

WS2813 是 WS2812 的升級版本。

WS2813 是一款智能控制 LED 光源,控制電路和 RGB 芯片集成在一個 5050 組件中。其內部包括智能數字端口數據鎖存器和信號整形放大驅動電路。還包括一個精密內部振盪器和一個 12V 電壓可編程恆流控制部分,

達到高度一致的色彩效果。

數據傳輸協議使用單一 NZR 通信模式。像素上電複位後,DIN 端口接收來自控制器的數據,第一個像素採集初始 24 位數據,然後發送到內部數據鎖存器,其他數據通過內部信號整形放大電路重新整形,通過控制器發送到下一個級聯像素 DO 端口。傳輸每個像素後,信號減少 24bit。每個像素採用自動整形傳輸技術,使像素級聯數不限於信號傳輸,僅與信號傳輸速度有關。

BIN 接收數據信號,然後在 24 位數據吞噬後將數據與 DIN 端進行比較,如果 DIN 不接收信號,則切換到 BIN 接收輸入信號,從而確保任何 IC 的損壞不會影響信號級聯傳輸並使 BIN 處於接收信號狀態,直到斷電後重啟。

刷新頻率更新為 2KHz,低幀頻和無閃爍出現在高清攝像機。

250us 或更多的複位時間,在中斷時不會造成錯誤的複位,它支持低頻和廉價的 MCU。

目前有 18mA 或 5mA 電流版本可供選擇,也可選擇高亮度或高性價比版本。也就是說,WS2813 提供了四個版本。

特點和優點

  • 控制電路和 LED 共享唯一的電源。

  • 控制電路和 RGB 芯片集成在一個 5050 組件中,形成一個外部控制像素。

  • 使用內置的信號整形電路來實現信號波形整形,而不會造成波形失真

  • 信號發生。

  • 內置上電複位和欠壓復位電路。

  • 每個像素的灰度級為 256 級,達到 “256 * 256 * 256 = 16777216” 全彩色顯示,

  • 刷新頻率達到 2KHz / s。

  • 串行級聯接口,數據接收和解碼僅依賴於一條信號線。

  • 雙信號線版本,信號斷點連續傳輸。

  • 任何兩點距離超過 3 米的傳輸信號都不增加電路。

  • 當刷新率為 30fps 時,級聯數遠遠超過 1024 點。

  • 數據傳輸速度高達 800Kbps。

  • 良好的色彩一致性可靠性,高性價比。

Description

WS2813 is an upgraded version of WS2812.

WS2813 is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. Its internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part,

which achieves highly consistent color effect.

The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology, making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission. 

The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off. 

Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.

250us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.

There’re in a choice of 18mA or 5mA current version, and also in a choice of high brightness or cost-effective version. That is to say, WS2813 is provided with four versions.

Features and Benefits

  •  The control circuit and the LED share the only power source.

  •  The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.

  •  Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of

  • signal takes place.

  •  Built-in power-on reset and brown-out reset circuits.

  •  The gray levels of each pixel are of 256 levels, which achieves “256*256*256=16777216” full-color display, and

  • the refresh frequency reaches to 2KHz/s.

  •  Serial cascade interface, data receiving and decoding depend on just one signal line.

  •  Dual-signal wires version, signal break-point continuous transmission.

  •  Any two point the distance more than 3m transmission signal without any increase circuit.

  •  When the refresh rate is 30fps, cascade numbers are far more than 1024 points.

  •  Data transmitting at speeds of up to 800Kbps.

  •  Good color consistency reliability, high cost-effective.
