摘要
以宏晶公司STC12C5A60S2单片机处理器作为控制器,以矩阵键盘作为输入设备,以RS485通信接口芯片作为数据更新方式,用北京青云公司生产的LCD3202401作为显示输出设备,研究设计了相应的硬件电路与显示驱动程序,在此基础上完成了人机交互系统的设计。充分利用成本低、资源少的单片机系统实现完善的人机交互功能。
A hardware circuit and display driver are designed by using the processor STC12C5A60S2 produced by Hongjing Company as the controller,the matrix keyboard as the input device,the 485 communication as the data updating method,and the LCD3202401 produced by Beijing Qingyun Company as the output device.On the basis of this a human-computer interaction system is designed.The improved HMI system is completed on the single chip system with low cost and scarce resources.
