Abstract

An 8-channel responder based on Freescale HCS12 single chip microcomputer is designed. The responder can display the number of the first player correctly. It also can count the scores and show the player with the highest score. The system includes four modules: CPU12, the SCI serial communication, digital display tube and timer. When competition signal input, it is been caught and then cause interruption, the timer is used to time accurately, the serial port is used to send and receive the start answer signal, judgment signal and other signals, the digital display tube is used to show the scores of the current player. LCD display tube shows subjects and answers. So the basic functions of the responder are achieved.
