Abstract

The pin functions and control instructions of the graphic liquid crystal display(LCD) module OCMJ8X15B were described.The interface technique of the graphic LCD and single-chip microcomputer(SCM) for the release lifetime tester was introduced,and the corresponding hardware circuit was presented.The interface driver program of C8051F020 was developed in C51.A written command and a debugged data operating subprogram of LCD were also provided.The designed circuit and program of C8051F series SCM and LCD interface could be directly applied to other equipment.
