基于STM32F427的状态监控CAN节点设计与实现

摘要

为了将传感器模块的信息发送到物联网CAN总线上，需要设计一个CAN节点用于转换数据。该文以STM32F427为主控器，通过软件硬件结合将串口数据转换为CAN数据，并设计一种防浪涌电路，适应车辆的复杂电源环境。实际应用表明，该CAN节点具有转换速度快、误码率低的优点。%In order to send sensor module information on the Internet of CAN bus,need to design a CAN node is used to transform the data.Taking STM32F427 as the host control er,Combining software hardware converts serial data to the CAN dat,and design a kind of anti surge circuit,adapt to the complex of the vehi-cle power supply environment.Practical application shows that the CAN node has converted the advantag-es of quick speed,low error rate.
