| Abstract: | The composition of the airborne computer system based on a digital signal processor DSP TMS320LF2407A is presented. Due to the complex and real-time property of the serial communication for a small UAV flight control system, mixed programming, modularization approach, circulating buffer technique, and frame assorting technique are used for interrupt service and frame selection of serial port programs, and realizes the communication of serial data and recognition, extraction of control commands, and parts of the flow charts are also given. The problems and its solutions in system debugging are discussed. A long time test shows the program is reliable and real-time, and satisfied with the performance of serial communication for UAV flight control system. |
