Design of Embedded Demo System Based on Processor LPC2294

随着嵌入式技术迅速发展,基于ARM的嵌入式技术应用越来越广泛,研究基于ARM的嵌入式系统已成为一个热点。LPC2294是一款以ARM7TDMI-S为内核的处理器,片上集成了丰富的接口电路,广泛应用于工业控制、医疗系统、访问控制、POS机、通信网关、协议转换器等。设计一个基于LPC2294处理器的嵌入式演示系统,首先介绍该芯片的基本功能,然后阐述了基于该芯片的嵌入式演示系统的硬件设计,包括电源、时钟、JTAG及其他接口电路设计,最后描述了该演示系统的软件实现,包括启动代码和应用程序设计。

With the rapid development of embedded technology,the ARM- embedded system is used widely. The research on ARM- embedded system becomes one of the most popular directions.LPC2294,based on ARM7TDMI- S,is a processor and integrated with rich interface circuits,which is very well suited for industrial control,medical systems,access control,point- of- sale,communication gateways,protocol converters and embedded soft modems as well as many other general- purpose applications. In this paper,it designs an embedded Demo system based on the processor LPC2294. It firstly introduces the basic function of this chip; secondly describes the hardware design of the embedded demo system based on the chip,including power,clock,JTAG and other interface circuits; lastly presents the software design,including the start code and application program.
