摘要
随着计算机技术、微电子技术和网络技术的迅速发展,嵌入式系统在工农业等诸多领域得到了广泛的应用。传统的8位单片机已经暴露了本身资源有限的缺点,越来越不能适应日渐复杂的应用需求,而随着32位处理器价格的不断下降,采用更高性能的32位处理器作为嵌入式系统的核心成为更加合理的选择。ARM处理器是目前公认的业界领先的32位嵌入式RISC微处理器,已成为许多行业嵌入式解决方案的RISC标准。开发一个集嵌入式控制、高效数据采集和网络通信于一体,并提供友好的人机操作界面的硬件平台,对于提高智能嵌入式系统可靠性、组网灵活性很有意义。据此本文完成了基于CS89712的LCD显示(含触摸屏)、以太网和MAX125数据采集的嵌入式系统的硬件设计。
With the development of the computer technology, microelectronics technology and network technology, embedded-system is adopted in the fields of the industry, agriculture,etc. But the traditional 8-bit MCU can't content the request of the application that is becoming more and more complex. And with the background of persistent descend in price of the 32 bit microcontroler, the better choice is adoptting highperformance 32-bit microcontroller as the core of embedded systerm. ARM processor is a kind of advanced 32-bit embeded RISC microprocessor, it has been the embedded solution's RISC standard. It's important to develop a hardware platform, which is an integrated platform of embeded control?high efficient data processing?network communication, and provides friendly human interface?According to this, this paper finished an Embedded Application System based on ARM CS89712, which is developed with LCD(Touch Panel included) ?Ethernet and MAX125 data acquisition.
