嵌入式TCP/IP协议源代码，能够在ARM嵌入式开发板上实现

uclinux2.4中自带了sl811的驱动，当用户使用时需对其做一些修改。本程序是邵仕泉、张红雨针对自己的应用在原有程序基础上修改的，在与原程序对照后可发现修改工作有很多，这可以作为参考，帮助读者写出自己的sl811驱动。-uclinux2.4 sl811 were onboard the driver, when users need when its done with some modifications. This procedure is SHAO Shi-chuen, bo, in light of their application procedures on the basis of the original amendment, in contrast with the original program can be found there is a lot of changes, which could serve as a reference to help readers to write their own sl811 drive.

嵌入式神舟系列，单片机开发试验仪，神舟3号开发板，stm32_ADC实现模数转换。ADC采集频率为12MHz，采集管脚PC3，采集数据经过平滑滤波，排除瞬间干扰。串口输出转换电压值，串口波特率为9600，数据位8，无校验，停止位1。
