A protocol for sending data between two Arduino devices, or between an Arduino and another device through a serial port

Serial Protocol

SerialProtocol 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

Copy the src\SerialProtocol folder to:

• Windows: %USERPROFILE%\Victor\Documents\Arduino
• Linux: ~/sketchbook/libraries or /usr/share/arduino/libraries
• Mac: Documents/Arduino/libraries

Note: You must restart the Arduino IDE if it was running before you copied the files.

Samples

The samples folder contains examples for both Arduino and Raspberry PI. If you upload the Arduino sketch and then run the Raspberry PI application, 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
