摘要：通過計(jì)算機(jī)的鼠標(biāo)、鍵盤操作與具有通用異步收發(fā)(UART)裝置功能的復(fù)雜可編程邏輯器件(CPLD)通信,使復(fù)雜可編程邏輯器件控制數(shù)碼管顯示數(shù)字.即以復(fù)雜可編程邏輯器件為接口以實(shí)現(xiàn)計(jì)算機(jī)控制外圍設(shè)備工作，并總結(jié)利用計(jì)算機(jī)來控制電機(jī)工作是可行的.

(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
