| Abstract: | An approach of asynchronous serial communication programming is introduced, which is used for communicating between PC and embedded system based on STC89C54RD+ with ISP characteristic. The communication protocol is presented and the programming technique of layered structure frame is proposed also. The serial communication program is developed in Keil C51. This mechanism can improve the encapsulation and modularization in programming, while the performance of concurrence and real-time data processing capacity is enhanced in serial data communication. |
