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 */
}
