How to Fetch and Display Data from DHT22 Sensor on AVR32UC with Zephyr OS?
hello @Dtynin did u wrap ur queue operations with mutex locks. something like this 👇 
SemaphoreHandle_t xMutex;

xMutex = xSemaphoreCreateMutex();

void readSensorTask(void *pvParameters) {
    sensor_data_t sensorData;
    for (;;) {
        
        if (xSemaphoreTake(xMutex, portMAX_DELAY)) {
            xQueueSend(sensorQueue, &sensorData, portMAX_DELAY);
            xSemaphoreGive(xMutex);
        }
        vTaskDelay(pdMS_TO_TICKS(1000));
    }
}

void processDataTask(void *pvParameters) {
    sensor_data_t sensorData;
    for (;;) {
        if (xSemaphoreTake(xMutex, portMAX_DELAY)) {
            if (xQueueReceive(sensorQueue, &sensorData, portMAX_DELAY)) {
             
            }
            xSemaphoreGive(xMutex);
        }
        vTaskDelay(pdMS_TO_TICKS(10000));
    }
}
SemaphoreHandle_t xMutex;

xMutex = xSemaphoreCreateMutex();

void readSensorTask(void *pvParameters) {
    sensor_data_t sensorData;
    for (;;) {
        
        if (xSemaphoreTake(xMutex, portMAX_DELAY)) {
            xQueueSend(sensorQueue, &sensorData, portMAX_DELAY);
            xSemaphoreGive(xMutex);
        }
        vTaskDelay(pdMS_TO_TICKS(1000));
    }
}

void processDataTask(void *pvParameters) {
    sensor_data_t sensorData;
    for (;;) {
        if (xSemaphoreTake(xMutex, portMAX_DELAY)) {
            if (xQueueReceive(sensorQueue, &sensorData, portMAX_DELAY)) {
             
            }
            xSemaphoreGive(xMutex);
        }
        vTaskDelay(pdMS_TO_TICKS(10000));
    }
}
