摘要
介绍了在嵌入式操作系统VxWorks下串口驱动程序的结构和原理,分析了基于PCI总线的多串口扩展卡的标准驱动开发过程,并实现了多串口卡共享中断。
The structure and mechanism of serial port driver on the RTOS VxWorks are introduced, then the development of standard device driver for the multi-serial-port card based on the PCI bus is analyzed, and multi-serial-port card working in IRQ sharing mode is achieved.
