单片机与CAN (控制器局域网)总线连接的传统

方式是将CPU与总线控制器和总线收发器相连后再

接入总线网络,这样使CPU外围电路复杂化,整个系

统受外部影响较大。为了解决这一问题,很多单片机

厂商纷纷将CAN控制器集成在单片机芯片上。-Microcontroller and CAN (Controller Area Network) bus to connect the traditional way is the CPU and the bus controller and bus transceivers connected to the bus after the access network, thus complicating the CPU peripheral circuit, the entire system by the external a greater impact. In order to solve this problem, manufacturers have a lot of single-chip will be integrated in the single-chip CAN controller chip.
