| Abstract: | In order to make UAV flight control system response to external events faster and achieve real-time processing capability, interrupt is a very effective means.This paper introduces a small UAV flight control system based on TI's DSP chip TMS320LF2407A,and gives a method on how to expand and manage the external interrupt of the UAV flight control system based on CPLD.It also introduces the hardware interface design,the program design and simulation results of the interrupt control system in detail.This design has been success- fully applied to a small UAV flight control system,and has improved the UAV flight control system on the external interrupt events man- agement and real-time processing capabilities. |
