摘　　要：本文介绍了利用STC89C58RD+单片机做为主控芯片,GPRS模块SIM300做为短消息接收器的LED条形图文显示屏系统的软硬件设计。其中,单片机相当于整个系统的"神经中枢",既要在AT命令下通过串口读和删除GPRS模块收到的短消息并进行处理,又要控制条形屏显示相应的信息。It introduced a design Of hardware and software system of the bar picture and words LED display ,in which ,single chip computer of STC89C58RD＋ is the master control chip, GPRS module SIM300 is the short news receiver. Among them, the single chip is equal ＂the nerve center＂ to the overall system. It not only must read and delete the short news under at order through the serial port which the GPRS module receives and carries on processing, but also must control the linearity screen demonstration corresponding information.
