This paper first introduces the characteristics of the 80 C1 96KC microcontroller and the new features as well as the basic situation of the MGLS-12220 LCD module. The design of the driver and interface circuit of the display module controller SED1 520 is then given It and the two basic interface 1 96 microcontroller hardware circuit and the way. Taking the indirect access method as an example, the article lists the detailed MCS-96 assembly language control program, and explains the program code and related logic in detail. Finally, some problems needing attention in hardware design and software programming are put forward.
