FreeRTOS - Design Patterns for RTOS

Which of the following is the correct FreeRTOS API call for a producer task to send data to a queue?

void producerTask(void *params) {
    int data = 10;
    // Send data to queue here
}

AxQueueSend(queueHandle, &data, portMAX_DELAY);

BxQueueReceive(queueHandle, &data, portMAX_DELAY);

CxTaskCreate(queueHandle, &data, portMAX_DELAY);

DvTaskDelay(queueHandle);

Step-by-Step Solution

Solution:

Step 1: Identify the correct API for sending data to a queue
FreeRTOS uses xQueueSend() to send data from a producer to a queue.
Step 2: Check other options for correctness
xQueueReceive() is for receiving data, xTaskCreate() creates tasks, and vTaskDelay() delays tasks, so they are incorrect here.
Final Answer:
xQueueSend(queueHandle, &data, portMAX_DELAY); -> Option A
Quick Check:
Send data = xQueueSend [OK]

Quick Trick: Use xQueueSend to put data into the queue [OK]
