RGB LED WS2811 / WS2812 / APA106 component
A simple chained RGB LED controller IC allowing multiple LEDs to be controlled using a serial data stream. Compatible with the WS2811, WS2812, WS2812B, APA104 and APA106 Type Controller ICs. Allows RGB LEDs to be driven with full 24-bit colour depth. Allows single chains, 2D arrays and 3D cube formations to be simulated. Requires a high speed microcontroller to generate the critical timings to drive the device.

|
|
Data Order |
| Configures the order the colour data is clocked out to the LEDs | |
|
Reset Time (uS) |
| Blanking reset period to reset the LED shift chain and start from the beginning | |
|
|
T0H (uS) |

|
T0L (uS) |
| Logic 0 low time in microseconds | |
|
|

LED Properties |
|
|
LED Arrangement |
| Controls the arrangement of the LEDs on the panel. 1D - Creates a straight line of LEDs 2D - Creates an X by Y Array of LEDs 3D - Creates an X by Y by Z Array of LEDs | |

LED Count |
| Total number of LEDs in the design | |
|
|
Arrangement |
| LEDs will likely be arranged in one of two ways. Parallel = Each row of LEDs run from left to right - easier to address but harder to wire. Alternating = Each row of LEDs runs in an alternating direction - harder to address but easier to wire. | |

| Flips the X axis if the LEDs are wired from the right hand side of the display. | |
|
|
Flip Y |
| Flips the Y axis if the LEDs are wired from the under side of the display. | |
