Event groups allow a task to wait in the Blocked state for a combination of multiple conditions or flags. This is highly useful for synchronizing multiple events (e.g., waiting for WiFi connected Sensor calibrated AND Flash initialized). Task Notifications
void vTaskFunction(void * pvParameters) for(;;) // Task code here vTaskDelay(pdMS_TO_TICKS(1000)); // Delay for 1 second Use code with caution. 2. The Scheduler freertos tutorial pdf
In traditional bare-metal programming, code runs in a continuous while(1) loop. This super-loop executes tasks sequentially. If one task takes too long, every subsequent task is delayed. Event groups allow a task to wait in
#include "FreeRTOS.h" #include "task.h" // Task Function Definition void vBlinkLEDTask(void *pvParameters) // Initialization code for the specific task pinMode(LED_PIN, OUTPUT); while(1) digitalWrite(LED_PIN, HIGH); // Block the task for 500 milliseconds vTaskDelay(pdMS_TO_TICKS(500)); digitalWrite(LED_PIN, LOW); vTaskDelay(pdMS_TO_TICKS(500)); int main(void) // Hardware initialization here... // Create the task xTaskCreate( vBlinkLEDTask, // Function pointer "LED Blinker", // Text name for debugging 1024, // Stack size in words NULL, // Parameter passed into the task 1, // Task priority (higher number = higher priority) NULL // Task handle ); // Start the scheduler vTaskStartScheduler(); // The code should never reach here for(;;); Use code with caution. Queue Management If one task takes too long, every subsequent task is delayed
