A Design of Basic Gate Circuit ICs Detection System

摘要

This paper presents a design method about the basic gate circuit ICs detection system based on microcontroller. We analyze the function of the detection system and give its design and implementation methods. We transmit high and low level to the inputs of 74LS series gate circuit IC, and acquire the signal of the outputs of the IC. Then we can know logical function of the IC is right or not by comparing the output of the gates with the theoretical value of the gates. In addition, we can know whether each gate's logical function is right. College students can improve the efficiency of experiments with the help of the detection system.
