摘要
采用 SJA1000作为 CAN 控制芯片,使用 PDIUSBD12作为 USB 的控制芯片,并利用AT89C52作为微控制器,设计了基于 USB 的 CAN 总线智能适配卡的硬件结构。在此基础上,设计了适配卡的软件实现方案。针对 CAN 总线容易受到外界干扰的弱点,使用6N137进行信号隔离。
This paper introduces the hardware structure of a CAN bus intelligent adapter based on USB adopting SJA1000 as CAN control chip, PDIUSBD12 as USB control chip and AT89C52 as microcontroller. It also introduces the software implementation project of adapter. 6N137 is adopted as signal isolation to solve outside interference weakness of CAN bus.
