摘要
以16PCI954芯片为例讨论了多串口扩展卡(8个串口)非Vxworks标准串口驱动方式UART模式下驱动程序的实现,内容包括:16PCI954芯片功能简介、Vxworks操作系统简介、Vxworks操作系统下驱动程序的类型介绍、16PCI954芯片多串口扩展卡驱动程序的实现,同时对部分串口控制信号也进行了讨论并实现,使读者更好地理解整个驱动的工作过程,稍加修改即可用于自己的实际项目。
This paper discusses in detail the implementation of Multi-serial device driver （UART MODE） based on the OX16PCI954 chip. Although it seems that it does not conform to the Vxworks device driver standard, it is more agreeable and applicable than the traditional ones when used. Meanwhile, How to control the state of channel is also addressed and analyzed.
