显示模块GU140×32F-7050的接口设计与应用

Interface Design and Application of Display Module GU140×32F-7050

为实现某控制装置文字和图形的显示,设计显示模块GU140×32F-7050的接口。硬件接口采用MC9S12DP512作为MPU,通过并行接口与显示模块连接;软件接口包括数据写入、初始化、显示、窗口定义和窗口选择。根据点阵图获取汉字、数字、字母或图形的图像数据,以2种方式调用显示接口函数得到相同的显示效果,并给出相应的程序代码。目前该显示模块已批量应用于某控制装置,实际应用表明,显示模块GU140×32F-7050工作稳定、可靠性高。

The interface of display module GU140 × 32F-7050 is designed to realize the text and graphpics display of certain type control device. It adopts MC9SI2DP512 as it＇s MPU, they connect with display module by parallel interface. The software interface includes writing data, initialization, display, window definition and window selection. The image data of Chinese characters, numbers, letters or graphics is acquired according to the dot matrix diagram. And the same effect is getted by two ways of calling display interface functions with corresponding code. Now the display module is widely used for some control device. The practical application shows that： the display module GU140 ×32F-7050 is stable and reliable when working.
