I'm trying to Blink 2 leds using freertos. The code in generated by CubeMX. When generating it shows like the image attached below. So I go to Sys tab and select timebase source as TIM1. When I flash the code I'm not able to see any output.
When I still generate the code without changing the timebase source(i.e. timebase source as SysTick), I got an error TIM_HandleTypeDef is not defined(at this void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)). So I included #include "stm32f4xx_hal_tim.h" this line. The code got compiled but not able to see any led blinking on my board.
My main function :
int main(void)
{
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
MX_GPIO_Init();
MX_DMA_Init();
MX_USART2_UART_Init()
osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
/* USER CODE BEGIN RTOS_THREADS */
/* add threads, ... */
if( xTaskCreate( TaskLED1_Blink, "BlinkLED1", 200, NULL, 1, &Task_LED1 ) == !pdPASS)
{
return 0;
}
if( xTaskCreate( TaskLED2_Blink, "BlinkLED2", 200, NULL, 1, &Task_LED2 ) == !pdPASS)
{
return 0;
}
/* 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 */
}
My tasks code :
void TaskLED1_Blink(void *pvParameters)
{
while(1)
{
HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_12);
HAL_Delay(500);
vTaskDelay( pdMS_TO_TICKS( 20 ) );
}
}
void TaskLED2_Blink(void *pvParameters)
{
while(1)
{
vTaskDelay( pdMS_TO_TICKS( 20 ) );
HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_13);
HAL_Delay(500);
}
}
Please help me out with this.
