Arduino Serial Protocol

ArduinoSerialProtocol is a protocol for sending data between two Arduino and/or Raspberry PI devices over serial.

Message structure

• Message start marker: 1 byte
• Message size: 1 byte
• Payload (message body): variable number of bytes (max 255)
• Checksum: 1 byte

Total message size (bytes): Payload + 3

Install Arduino Libraries

1. Download the Repository as a .zip file.
2. In Arduino IDE, go to Sketch> Include Library> Add .zip Library.
3. Select the Downloaded .zip File.

Examples

Arduino Instructions

Open the arduino_app in the Arduino IDE and upload to your Arduino.

Raspberry Pi Instructions

1. Clone this repository and navigate to the SerialProtocol/extras/raspberry_app folder.
2. Make the file raspberry_app.cpp
3. Run the new file. You should see the two devices exchanging a data structure with different numeric types.

Acknowledgements

SerialProtocol is inspired by Arduino-EasyTransfer. It brings a few improvements (over v2.1):

• The start marker (header) is one byte shorter
• A detailed error code is given in case of communication failures
