我们实验室（lingshunlab.com）进行了两组CANBUS通讯实验，分别采用了Arduino Uno与MCP2515模块的组合，以及Arduino Nano与MCP2515模块的组合。元件详解 在本次CANBUS通讯实验中，我们选用了两种不同的元件组合：一种是Arduino Uno与MCP2515模块的搭配，另一种则是Arduino Nano与MCP2515模块的组合。这些元件在实验中发挥了...
The MCU is responsible for the control of the function circuit and the CAN controller. For example, the CAN controller parameters are initialized when the node starts, the CAN frame is read and sent through the CAN controller, etc. 4. CAN Communications When the bus is idle, all nodes can...
具体为:半双工,使用RTS信号控制RS485调制解调模块的数据方向,函数为: uart_set_line_inverse(1, UART_SIGNAL_RTS_INV); /*This Sketch demonstrates how to use the Hardware Serial peripheral to communicate over an RS485 bus. Data received on the primary serial port is relayed to the bus acting as ...
This is universal CAN library for STM32 Arduino use. Originally this was created to be used with Speeduino EFI and other CAN bus projects used in car environment. But has since grown into universal CAN bus library for Arduino STM32. This library should support all STM32 MCUs that are also...
CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differenti...

Today, you can find up to 70 ECUs in a modern car, e.g. the engine control unit, airbags, audio system, etc. CAN is a serial communication bus designed for industrial and automotive applications. For example, they are found in vehicles, farming equipment, industrial environments, etc. ...
