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.
