(Institute of Information engineering, Guangdong University of Technology, Guangzhou, Guangdong, 510006, China) Abstract: Computer is communicated with Complicate Programmable Logic Device (CPLD) which is in possession of function of Universal Asynchronous Receive and Transmit (UART) by mouse and keyboard. Segment-LED that is some is on/off shows the number controlled by CPLD. It means CPLD is an interface in order to control the peripheral equipment through computer operation. Make a conclusion, motor which is controlled by computer using this method is feasible
