摘　　要：介绍了基于ARM微控制器的可编程控制器(PLC)的硬件电路实现方法,给出了以LPC2214芯片为核心的硬件设计的原理框图,详细阐述了输入输出单元电路以及外围接口电路的设计。由于LPC2214芯片内部集成了多种功能,简化了PLC硬件结构。该可编程控制器具有配置简单,扩展方便,可靠性高的特点。A method of developing Programmable Controller based on ARM Micro- controller is introduced in this paper. The principle graphic of hardware design based on LPC2214 is presented, and the design of I/O circuits and peripheral interface is expatiated in detail. LPC2214- compatible micro- controller integrated with much function, this character of LPC2214 simplifies the hardware structure of PLC. It is simple in configuration, convenient to extend and outstandingly reliable.
