A servo-controller is designed based on the MCU chip C8051F120 and CPLD chip EPM570T100
the controller has LCD display and menu display through UART setting
and the real-time control information could be displayed on the LCD screen. The hardware structure and software flow design of the controller has been given. The experiment proved that the display module has the advantages of stable display and faster refresh rate
and satisfied the requirement of real-time display of the servo control system.
