摘要
介绍了一种基于ARM9和CPLD架构的嵌入式输入输出系统的软硬件设计。系统以工业级EP9315为核心,扩展了LCD、触摸屏、以太网、串口和USB等控制接口;以MAX2_EPM240为核心,进行了输入输出模块的设计。该系统成本低、工作稳定、通用性强,可在许多场合取代PLC的I/O模块工作。
The software and hardware design of embedded input and output system based on ARM9 and CPLD was introduced. The system adopted LCD, touch screen, ethernet, serial and USB control interfaces taking the industrial grade EP9315 as the core, and designed input and output model taking MAX2_EPM240 as the core. This system has many advantages such as low-cost, stable running, strong universality, and especially can replace PLC in many industrial fields.
