🕹️(035) Message Queue in FreeRTOS
FreeRTOS中的消息队列：
//消息队列句柄
QueueHandle_t xQueue;
//消息元素
struct QueueItem_t{
uint32_t xContent;
}
//主函数中创建消息队列，容量为20个QueueItem
xQueue = xQueueCreate(20, sizeof(QueueItem_t));
//发送端任务
QueueItem_t data;
data.xContent=65535;
xQueueSend(xQueue,&data,portMAX_DELAY);
//接收端任务
QueueItem_t data;
xQueueReceive(xQueue,&data,portMAX_DELAY);
printf("received:::%ul",data.xContent);
