内容简介: 介绍了Linux下的串口驱动的设计层次及接口, 并指出串口与TTY终端之间的关联层次(串口可作TTY终端使用), 以及Linux下的中断处理机制/中断共享机制, 还有串口缓冲机制当中涉及的软中断机制 其中有关w83697/w83977 IC方面的知识, 具体参考相关手册, 对串口的配置寄存器有详细介绍, 本文不再进行说明.-Descr iption: This paper introduces the Linux serial port driver under the level of design and interface, and pointed out that with the TTY terminal serial correlation between the level (TTY serial port can be used for end-use), as well as under Linux interrupt handling mechanisms/interrupt-sharing mechanism, as well as serial port buffering mechanisms involved soft interrupt mechanism w83697/w83977 IC related knowledge, the specific reference to the relevant manual configuration of the serial register is detailed in this paper no longer explain.
