谢谢您，我在main()中做了初始化了 int main(void) { / USER CODE BEGIN 1 / / USER CODE END 1 / / MPU Configuration--------------------------------------------------------/ MPU_Config(); / Enable the CPU Cache / / Enable I-Cache---------------------------------------------------------/ SCB_EnableICache(); / Enable D-Cache---------------------------------------------------------/ SCB_EnableDCache(); / MCU Configuration--------------------------------------------------------/ / Reset of all peripherals, Initializes the Flash interface and the Systick. / HAL_Init(); / USER CODE BEGIN Init / / USER CODE END Init / / Configure the system clock / SystemClock_Config(); / USER CODE BEGIN SysInit / / USER CODE END SysInit / / Initialize all configured peripherals / MX_GPIO_Init(); MX_TIM6_Init(); MX_USART1_UART_Init(); MX_USART6_UART_Init(2000000); MX_FDCAN1_Init(); MX_FDCAN2_Init(); sdram_init(); MX_SDMMC1_SD_Init(); MX_FATFS_Init(); PrintfLogo(); / USER CODE BEGIN 2 / //PCF8574_Init(); //HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, GPIO_PIN_RESET); //HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_RESET); / USER CODE END 2 / / Call init function for freertos objects (in freertos.c) / MX_FREERTOS_Init(); / Start scheduler / osKernelStart(); / We should never get here as control is now taken by the scheduler / / Infinite loop / / USER CODE BEGIN WHILE / while (1) { / USER CODE END WHILE / / USER CODE BEGIN 3 / } / USER CODE END 3 / }
