摘要
在一些应用场合,汉字显示使微型应用系统的界面非常简单、直观,若使用价格低廉的LCD1602实现更能提高系统的性价比。为此文章对LCD1602的汉字显示原理做了说明,除常规的方法外,创新性地提出了拼接法和动态刷新法来满足不同系统的要求。首先通过Proteus+KeilμVision4的联机仿真调试进行了软硬件原理验证,然后在AT89S52的单片机开发板上运行,达到了预期的效果,具有一定的应用参考价值。
The display interface was very simple and intuitive by Chinese characters in some applications.The cost performance was better achieved by the use of low prices of LCD1602.In this paper,the principle of Chinese characters display technology of LCD1602 was described.Besides the conventional methods,the new methods of putting character together and dynamic refreshing methods were innovative proposed to meet the requirements of different systems.First the verification of principle of hardware and software was carried out by the online simulation through Proteus+KeilμVision4 integrated development environment.Then it runs on the AT89S52 MCU development board and achieves the expected effect,which has certain application reference value.
