WS2812B - Patterns
• WS2812B LED Strip / Ring / Stick / Board x1
In this example, we will be using the AmebaD board to control the WS2812B RGB LED, using the SPI peripheral to create the waveform necessary for the LEDs.
WS2812B_Patterns allows you to create different light patterns with many different colors.
Firstly, connect the WS2812B to the Ameba board as shown in the following diagrams.
BW16 type C:
AW-CU488 Thing Plus:
To create different light patterns with many different colors, use WS2812B_Patterns.
Open the example in “File” → “Example” → “AmebaWS2812B” → “WS2812B_Patterns”.
In the sample code, modify NUM_OF_LEDS to be the number of LEDs that you have connected.
Next compile and upload to Ameba, then press the reset button. You will see the WS2812B displaying a color wipe, theater chase, rainbow, and theater chase rainbow light patterns in loop.
