Arduino CAN Example

This Example uses 4 Arduinos as ECUs

• 2 equipped with DHT11 Temp and Humidity Sensor
• 1 with String Generator (this configuration can be changed via jumpers on D0 (Temp), D1 (Humidity) and D2 (String Gen))
• 1 to request information and show on LCD

the idea here is to use a PC with any sort of CAN adapter and send a CAN message with ID 0x01 (Temp) , 0x02 (Humidity) or 0x03 (String) with bit 1 on byte 0 to request the values from the Arduino ECU's on the CAN BUS and/or have the 4th arduino to display the information over LCD.

Dependencies

• MCP2515 Lib from AutoWP
• DHT11 Lib from AdaFruit
• Adafruit Unified Driver from Adafruit
• 16x2 LCD I2C Lib
