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

(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
