微控制器与CAN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。文章设计了一种基于具有ARM7核处理器且内部集成四路独立CAN控制器的LPC2294的CAN总线分布单元,依靠ARM微控制器的强大的控制处理能力和丰富的外设,实现了智能化的控制和更大程度的系统集成。
The traditional way of connecting the microcontroller with CAN bus is to connect the CPU with the bus controller and the bus transceiver and then connect to the bus network, thus complicating the peripheral circuits of the CPU and greatly affecting the whole system from the outside. The article designs a CAN bus distribution unit based on the LPC2294 with ARM7 core processor and integrated four independent CAN controllers. By relying on the powerful control processing capability and rich peripherals of the ARM microcontroller, it realizes intelligent Control and greater system integration.
