Arduino-CANBus-Monitor

MCP2515 canbus module to Monitor Canbus traffic.

  • V7.10 USBCAN-001

  • V7.20 USBCAN-V720

  • V8.00 USBCAN-V800

Background

Windows application for monitoring CANBus is published here. This tool is designed to be used with this hardware. bazaar487719_1

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
