摘　　要：Zynq-7000 So C单芯片集成了两个ARM A9和FPGA,兼具ARM软件可编程性与FPGA硬件可编程性,在嵌入式系统中得到越来越多应用。针对Zynq-7000缺少LCD控制器的限制,提出了基于可编程逻辑扩展LCD接口的技术方案,LCD驱动与LCD控制器之间通过显示缓存交互,实现了简单可靠的液晶显示功能,满足了继电保护设备人机交互需求。该方案能简化硬件设计,成本低,具有较好的工程应用价值。Aiming at the Zynq-7000 So C is lack of LCD controller,a design scheme of LCD control system based on programmable logic is proposed in this paper.The LCD driver and LCD controller interact with each other through display memory.Results indicates that LCD control system functioned properly and flexibly with high reliability for the human-machine interaction of Relay Protection.
