LCD liquid crystal display is the key to man-machine interface technology. In this paper, based on single-chip LCD liquid crystal display control technology is studied. This article set out to use single-chip microcomputer (STC89C52) control method LCD1602 display. First of all, this paper LCD1602 LCD (HD44780) and the principle of the dot matrix display font access method code, followed by Proteus simulation software circuit simulation to build relevant and connected to the Keil software to prepare, edit and compile the relevant generating . Hex driver circuit simulation, the success of the simulation cycle required to display the content. The main programming language used was compiled. After the success of simulation in this paper for further development in the single-chip on-board procedures for burning. This paper describes the design of the actual production of products is based on the schematic diagram of the PCB board to generate, and finally through the purchase of components, component testing, circuit welding, product testing was completed the design of the whole process.
