| 摘 要： | PC104嵌入式计算机在工业控制中得到了广泛应用,但不具备与CAN总线的通信能力,在CAN总线控制系统中,使用受到了限制。介绍了在Linux下PC104总线驱动程序的设计方法,并且以AVR单片机为协处理器,利用双端口RAM进行数据缓冲的方法,实现了PC104总线与CAN总线通信。该方案在实际工业控制系统中得到运用,运行稳定可靠。

| Abstract: | PC104 embedded computer is applied widely in industry control,but it can not communicate with CAN bus,so the use is limited in CAN bus control system.The article introduces the design of PC104 bus driver program under the Linux and the realization of communication between PC104 bus and CAN bus by dual-port static RAM carrying on the data buffer with an AVR coprocessor.The scheme is used in actual industry control system and works steadily and reliably. |
