提出了一种基于VC++上位机和下位机的串行通信方法及利用Proteus仿真实现系统的新方法;从系统硬件平台设计、微机操作控制界面设计、Proteus仿真实现3方面详细介绍了整个通信系统的设计过程,并给出了仿真结果。

本资源主控为STC89C51 51单片机外接ADC0832采集YL69土壤湿度湿度传感器传来的土壤湿度信息 通过数码管实时显示土壤湿度值，并判断是否需要浇水 如果判断出需要浇水，单片机控制水泵进行浇水操作。 数码管驱动电路采用三极管增加驱动能力，还增加了key1、key2、key3三个按键 按键可以用来控制浇水的阈值，判断是否需要浇水。 同时也可扩展为自动浇水和手动浇水的功能。

嵌入式系统的C语言设计

An embedded system is just a computer buried inside some other product. Surprisingly, you can know a great deal about programming and computing and still get lost in the arcane world of embedded systems. In the world of embedded systems programming, countless details — both hardware- and software-related — make the development process seem like a path that few have traveled and even fewer have survived. How do software, hardware, and firmware differ? How in the world does a 100,000-line program end up inside a device smaller than my fingernail? What is flash memory and why do I need a cache? What is the difference between a task and a process? Do I need to worry about reentrancy? As we progress through Embedded Systems Firmware Demystified, you will come to see that these questions are not as complex as they first appear. Embedded systems programming spans a wide range of activities from building programmable logic at the most concrete end to writing a UNIX™ process at the most abstract end. Bracketed by these poles, the industry has exploded in the last 20 years. In the late seventies, assemblers were considered luxuries. A typical embedded system used less than 64Kb of system memory (bits, not bytes!).

结合实际项目的开发经验，详细讲解了基于Xilinx Microblaze软核开发的整个流程，包括硬件平台搭建、软件平台开发、嵌入式操作系统的加载以及用非易失性存储设备对FPGA进行上电配置等内容。利用FPGA软核进行嵌入式系统开发，将得到越来越多的关注和应用。
