| Abstract: | This paper designed a kind of servo control real time display system based on Spardan3 series FPGA X-C3S5E and DM12864M displayer.This system receives data of encoder through RS232,and displays those data on the displayer real-time.This paper gives the hardware structure and software flow design,including the interface between FPGA and LCD12864;Besides,this paper introduced software design,have serial communication,data processing,division,data select and display model,which are easy to debug;also used status machine which make time sequence more clearly.The experiments indicated that the display system the hardware resource consumption of controller is low,high efficiency,good stabilization and good in generalization.It can satisfy the real-time display requirement of servo control system. |
