In order to ingeniously and efficiently use mailbox of μC/OS?Ⅲ operation system in the design of multitask pro?gram,a method to combine theoretical analysis with experiment was adopted. The application skills and method of mailbox based on μC/OS?Ⅲ operation system in the aspects of full duplex intertask communications, binary semaphore and delay func?tion were achieved. The experimental results show the flexible application of mailbox can not only realize the traditional intertask data communications,but also replace the mutual exclusion semaphore and implement the delay function.
