基于SOPC的通用液晶屏人机交互系统GUI的设计

Design of Man-Machine Interaction Systems Based on LCD Screen of SOPC

针对目前人机交互界面越来越复杂的应用需求,利用FPGA器件,设计了一种基于SOPC技术的触控显示GUI系统。系统使用FPGA器件驱动液晶屏和触控板,并内建SOPC软核处理器运行GUI图像接口软件模块,在使用时只需将显示的界面图像放到FLASH存储器中,利用一个串口与上位MCU相连接即可。相对于传统方法设计时间长,通用性差的缺点,本设计具有开发简单,界面美观的特点和极好的适用性。

In order to satisfy the requirements of more and more complex man-machine inter- face,one touched display GUI system based on SOPC technique is designed by using FPGA device. The LCD screen and touchpad is driven by FPGA device in this system. The GUI graphic interface module is run by build-in SOPC soft core processor. The method only brings the interface image needed into the FLASH memory. And next using a serial port connects to the host MCU, which has the advantages of simple development, elegant inter- face and excellent applicability, comparing with disadvantages traditional method with long-time design and poor universality.
