Based on the design of the MCU LCD dot matrix display screen Abstract With the rapid development of computer science and technology, the application of computer has penetrated into every corner of the national economy and peoples life, are increasingly changing the traditional way of human work and lifestyle, and single-chip microcomputer technology as an independent branch of computer technology, has a high cost performance, high integration, small size, high reliability, strong control function, low power consumption, low voltage, easy production, easy to carry, etc, so as to get more and more widely used.Today is an information age, the importance of the information it goes without saying that the means of access to information is especially important, accepted a good portion of the information comes from the people of vision, no matter use what means to obtain information and eventually need to have some kind of display mode.In some kind of display technology, represented by the liquid crystal display LCD flat panel display development the fastest, the most widely used.This design mainly adopts STC89C52 single-chip microcomputer as the LCD1602 LCD display system controller of the main line.STC89C52 single-chip microcomputer control through the pi
