摘要
本文介绍了一种基于PIC系列单片机与液晶显示控制器HT1621的接口实现,给出了控制时序图、硬件原理图和软件框图。在电气控制保护开关的具体应用中,该液晶显示控制器能够实现负荷轻重、漏电故障、漏电电流选择、时间设定等指示显示。实践证明,本文给出的方法正确,只要改变液径显示字符内容,可应用于多种人机信息交流中。
This article introduces a kind of LCD controller based on PIC series MCU. In the article the functions, the control scheduling, the hardware schema and the software diagram of the drivers are involved. It has been used for the control and can be displayed burthen degree, electric leakage failure, time tion. The method is right. It is used in information display for protective switching devices that design and leaky electricity selec-many mechanics.
