Arduino Canbus Dashboard

Introduction

Empty

Dashboard is an Instrument cluster or ICM instrument cluster module.

CAN standards

A controller area network bus (CAN bus) is a vehicle bus standard.

• Differential signaling
• CRC

ECU Electronic Control Unit

CAN 2.0 (classical CAN)

• eight bytes
• a typical baud rate of 500 kbit/s
• CAN2.0A, CAN2.0B,

CAN FD (releases 2012).

Some de facto standards for mechanical implementation: 9-pin D-sub type male connector

• pin 2: CAN-Low (CAN−)
• pin 3: GND (ground)
• pin 7: CAN-High (CAN+)
• pin 9: CAN V+ (power)

CAN C - Engine CAN (also known as chassis CAN): Fast communication speeds 125 kbps or 500 kbps

CAN B - Interior CAN (also known as body CAN): Communication speed 83 kbps

CAN and Arduino
