Arduino-CANBus-Monitor

MCP2515 canbus module to Monitor Canbus traffic.

• V7.10

• V7.20

• V8.00

Background

Windows application for monitoring CANBus is published here.
This tool is designed to be used with this hardware.

So, I made the hardware side with Arduino UNO+MCP2515 canbus module.

Trouble shooting

Use hardware serial for USB communication.
Therefore, the Arduino-IDE serial monitor cannot be used.
Debug uses software serial.

SoftwareSerial mySerial(4, 5); // RX, TX
