Abstract：The real-time property of the serial communication program for UAV(Unmanned Aerial Vehicle) flight controller was studied. The hard real-time serial receiving program which dealt with totally four different data frames was designed with four techniques: data frame picking-up in interrupt serve program, finite state machine theory, buffer sharing and code optimizing. Test results show that the program has reasonable time consumption and ideal hard real-time property. Meanwhile, it has an outstanding data frame picking-up ratio with high reliability and satisfies the requirement to control the UAV craft by serial communication.
