LED点阵显示屏可以显示数字或符号, 通常用来显示时间、速度、系统状态等。 本设计是16×64点阵LED电子课程表显示屏的设计。整机以美国ATMEL公司生产的40脚单片机AT89C51为核心，介绍了以它为控制系统的LED点阵电子显示屏的动态设计和开发过程。通过该芯片控制一个行驱动器74LS154和八个列驱动器74HC595来驱动显示屏显示。该电子显示屏可以显示各种文字或单色图像，全屏能显示4个汉字，采用16块8 x 8点阵LED显示模块来组成4个16x16点阵显示模式。显示采用动态显示，使得图形或文字能够实现静止、移入移出等多种显示方式。文中详细介绍了LED点阵显示的硬件设计思路、硬件电路各个部分的功能及原理、相应软件的程序设计，以及使用说明等。 关键词：AT89C52单片机；LED点阵显示；4*4键盘；LCD1602  ABSTRACT 目录 ABSTRACT LED dot matrix display as a new display device is composed of multiple independent LED light emitting diode package together. LED dot matrix display can display numbers or symbols, usually used to display time, speed, system status, and so on. This design is 16 × 64 dot matrix LED display design. Overall the United States produced 40 feet ATMEL AT89C51 microcontroller as the core, introduced to it as the electronic control system of LED dot matrix display dynamic design and development process. With this chip to control a row and eight drive column driver 74LS154 74HC595 to drive the display. The electronic display can display a variety of text or monochrome images, full-screen can display four characters, use 16 8 x 8 dot matrix LED display module to form four 16x16 dot matrix display mode. Display with dynamic display, making the graphics or text to achieve stationary, moved out of the other display. This paper describes the hardware of LED dot matrix display design ideas, the hardware circuit and the principle functions of various parts, corresponding software program design, and the use of descriptions.
