摘要
文中实现了文字电话通信前等待界面和通信中信息的液晶显示。使用Microchip公司生产的dsPIC33F数字信号控制器与16位开发板,以MPLAB为开发平台,使用C语言编程并通过C30进行编译完成对数字信号控制器的控制,从而实现控制器驱动液晶显示模块实现显示。利用点阵型液晶显示模块TSB1G7000的命令字实现显示界面的小图标设计和滚屏设计,并且实现了通信过程中双方通信数据的显示。实践表明,使用dsPIC33F数字信号控制器与液晶显示模块构成的显示系统可以满足文字电话的显示要求。
This paper designed the liquid crystal display of the waiting interface before communication and the information during communication of the textphone.Using Microchip’s dsPIC33F digital signal controller and 16 development board as hardware,MPLAB as platform,using the C language to program and C30 to compile in order to control the digital signal controller,and then realize the liquid crystal display under the control of the controller.The design of small icons,the display shift based on the command words and the display of both sides in communication were realized.Practice showed that the display system using dsPIC33F and TSB1G7000 can meet the display demand of textphone in communication.
