Abstract With the support of LiteOS real-time operating system, the overall functionality of embedded system needs to be achieved through the collaborative operation of multiple tasks and interrupt service program ISR. The serial communication port, as a shared resource, will be accessed concurrently by two or more tasks or interrupt service programs (ISR). To ensure the reliability and integrity of serial data communication, a universal frame structure design for serial data communication is proposed. Through in-depth analysis of the problems in serial data communication under the LiteOS system, an efficient and stable method for serial data transmission and reception under the LiteOS system is proposed.
