stm32l476v TIM15 CH2 PWM이 cubeMx에서 작동하지 않습니다.

Question

FreeRTOS로 STM32L576VGT를 시작하려고합니다.

나는 작업에서 LED가 깜박이고, 이제는 PWM을 설정하려고하는데, 주파수와 임무가 중요하지 않은 것은 "안녕하세요 세상"입니다.

모두 CubeMx를 사용하여 이루어 졌으므로 제대로 작동하지 않습니다.

tim.c은 main.c에에 TIM15

에 대한 CubeMx으로 생성 된 PCB가 이미 수행되고 그것이 하나에 연결되어 있기 때문에 내가 TIM15을 사용하고

int main(void) 
{ 
    /* USER CODE BEGIN 1 */ 
    /* USER CODE END 1 */ 
    /* 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_QUADSPI_Init(); 
    MX_LPUART1_UART_Init(); 
    MX_SPI2_Init(); 
    MX_I2C1_Init(); 
    MX_TIM15_Init(); 
    /* USER CODE BEGIN 2 */ 
// DISP_diplay_init(); 
    HAL_TIM_PWM_Start(&htim15,TIM_CHANNEL_2); 
    /* 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 */ 
} 

출력을 제어하려고합니다.

덕분에, 기예르모

는 sConfigOC.Pulse = 0;에 다른 값을 시도 했습니까?
