CANBUS发送代码(CAN_write) CANBUS接收代码(CAN_read) 实验效果 凌顺实验室(lingshunlab.com)分享使用Arduino Uno + MCP2515 模块和 Arduino Nano + MCP2515 模块 进行CANBUS通讯。 元件说明 模块特性: 1、支持CAN V2.0B技术规范,通讯速率1Mb/S 2、0~8字节长的数据字段 ...
spi转can模块功能:1、读状态;2、读写数据;3、can设备输入输出标识设置(spi 为从设备)。 一、硬件 1、spi部分只需要mosi、miso、clk就可以工作。(andunio_spi时钟频率:SPI_CLOCK_DIV64 orSPI_CLOCK_DIV128) 2、can部分采用DB9标准接口2为CANL、7为CANH。 二、时序操作(spi时钟250k) 1、读时序 a、写8位...

作为并非通信专业的汽车工程师，汽车CAN通信是必须掌握的，但是，记得刚开始上来一看什么定义（什么串行数据通信协议，什么物理层和数据链路层功能，什么帧处理，位填充。。。刚学的时候确实一脸懵）。所以，我只从汽车工程师的角度讲讲我能理解和用得到的CAN通信，才疏学浅，请各位指教！
7 Wire.read() 8 Wire.onReceive() 9 Wire.onRequest() Wire.begin() 和 Wire.begin(address) 1. 这里有两种用法: 1.如果调用函数时不带address参数,则设备作为iic主机加入总线通信, 2.如果带参数调用,则设备作为iic从机加入总线通信,同时初始化该设备的iic地址为参数address。
