Description

WS2812 driver for CC26XX platforms using SPI UDMA driver.

Prerequisities

• Add in Board.h Pin corresponding to used SPI MISO i.e. Neopixel data pin
• set Number of neo_pixels set using NB_PIXEL preoprocessor directive

#Example code

Number of neo_pixel set using NB_PIXEL preoprocessor directive.

WS2812_begin(Board_DP0);
WS2812_setPixelColor(0, 0xFF, 0, 0);
WS2812_setPixelColor(1, 0, 0xFF, 0);
WS2812_setPixelColor(2, 0, 0, 0xFF);
WS2812_show();
