Human ? Computer interface is indispensable in the application system with computer as the core. In order to solve the problems of the convenience of user operation,the engineering costs,the convenience of hardware/software operation and control the scale of hardware/software in the design of human?computer interface. The character type LCD module is used to design display part of the man?machine interface which use the MCS?51 microcontroller as CPU. The detail design of the hardware interface and the software design is provided,and the common problems during the design of the human?computer interface with character type LCD module is analyzed and the solution is given out. The character type LCD module has the advantages of high cost effective,simple hardware interface,flexible and convenient software operation,rich display content,small volume and low power consumption. For this reason,it is very appropriate for the development of the small and medium application system, such as pocket instrument and portable equipment.
