摘要
设备驱动设计是嵌入式系统开发的难点。针对本系统可靠性和实时性要求严格的特点,在详细分析VxW orks实时操作系统设备驱动机制的基础上,通过采用内核过程的方式实现了VxW orks下CAN设备驱动,达到了预期的目标。所给出的VxW orks下设备驱动设计的一般步骤为VxW orks其他设备驱动开发提供了参考。
Design of device-driver is a difficult task in embedded-system＇s developing. Considering the demand of reliability and near real-time of this system, the mechanism of devlce-driver based on RTOS of VxWorks is analyzed firstly, then the device-driver of CAN bus is implemented by using kernel-process technique. Through this method, expectant performance of target system is achieved. The general process of device-driver-design used in this paper can be refered by others device-driverdeveloping based on VxWorks.
