基于uClinux嵌入式操作系统的串行接口电路设计

近年，嵌入式系统的设计被应用到越来越多的领域，但由于嵌入式操作系统的应用是与硬件设计紧密相关的，因此，根据不同的应用环境，需对uClinux内核源码进行适当的修改。文中根据实际工程设计案例，对串行接口电路的硬件设计与uClinux内核的裁剪进行了详细的描述，为uClinux操作系统在嵌入式领域的应用起到了一定的借鉴作用。

The Disign of Serical Circuit Based on uClinux Embedded System

Recently, embedded system is used in more and more domain, but because it is based on the hardware circuit, so uC-linux kernel must be edit according to different enviroment. This paper based on the engineering case, elaborate how to design hardware and how to edit the uClinux kernel. This solution is useful for the uClinux embedded system ’s engineer application.
