摘要
在有关CAN总线通信的嵌入式设计中,经常需要PC机作为调试工具,以便在PC机上直观地观察数据,这就需要CAN转USB设备进行连接。笔者选用低成本的内部集成了CAN控制器和串口的ARM内核32位处理器STM32作为主体芯片完成CAN转USB模块的设计。该模块速度快、可靠性高,能够满足大部分场合的要求。
In the embedded design concerning CAN bus,PC as a debugging tool and data displayer asks for CAN-USB conversion. The commercial conversion always cost too much and it's difficult to popularize in low cost applications. The STM32 micro controller which internally integrating CAN controller and serial port controller was adopted to implement CAN-USB conversion. This module can satisfy most application because of high running speed and high reliability.
