STM32 HAL PlatformIO LED 闪烁示例

在自动生成的 main.c 中，使用以下 while() 循环：

stm32_blink.c

/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
  /* USER CODE END WHILE */

  /* USER CODE BEGIN 3 */
  HAL_GPIO_WritePin(LD1_GPIO_Port, LD1_Pin, GPIO_PIN_SET);
  HAL_Delay(1000);
  HAL_GPIO_WritePin(LD1_GPIO_Port, LD1_Pin, GPIO_PIN_RESET);
  HAL_Delay(1000);
}
/* USER CODE END 3 */

/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
  /* USER CODE END WHILE */

  /* USER CODE BEGIN 3 */
  HAL_GPIO_WritePin(LD1_GPIO_Port, LD1_Pin, GPIO_PIN_SET);
  HAL_Delay(1000);
  HAL_GPIO_WritePin(LD1_GPIO_Port, LD1_Pin, GPIO_PIN_RESET);
  HAL_Delay(1000);
}
/* USER CODE END 3 */

在 STM32H7 Nucleo 板上，这将切换绿色 LED。
