WS2812-STM32
Introduction
Drive individually-addressable LEDs with DMA. Supports LED drivers in the WS281x and SK6812 families and similar. Intended to be used with STM32 devices with a SPI peripheral capable of DMA.

The FX library is based od WS2812FX Arduino librarby by kitesurfer1404 - https://github.com/kitesurfer1404/WS2812FX
Usage
Clone this repository, or add it as a submodule, to your STM32 project under the Drivers/ directory.
Example: In main.c:
/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "ws2812b.h"
#include "ws2812b_fx.h"
/* USER CODE END Includes */
...
int main(void)
{
/* USER CODE BEGIN 2 */
WS2812B_Init(&hspi1);
WS2812BFX_Init(20);
/* USER CODE END 2 */
}
In your interrupt service routines:
/* USER CODE BEGIN Includes */
#include "ws2812b.h"
#include "ws2812b_fx.h"
/* USER CODE END Includes */
...
void SysTick_Handler(void)
{
/* USER CODE BEGIN SysTick_IRQn 0 */
/* USER CODE END SysTick_IRQn 0 */
HAL_IncTick();
/* USER CODE BEGIN SysTick_IRQn 1 */
WS2812BFX_SysTickCallback();
/* USER CODE END SysTick_IRQn 1 */
}
