DecaDuino

Ranging/synchronisation over UWB - DecaDuino library for Arduino

Brief

DecaDuino is an Arduino library which provides a driver for the DecaWave DW1000 transceiver, and modules based on this transceiver, such as DecaWave DWM1000. Since the DecaWave DW1000/DWM1000 is based on a Ultra Wide Band (UWB) Physical layer, DecaDuino can be used as an open framework for wireless Time-of-Flight (ToF) ranging systems.

Installation

You have to put this library in your Arduino libraries directory.

Hardware

An example hardware is DecaWiNo: https://wino.cc/decawino/

Start using DecaDuino with simple example sketchs

All example sketches are available as usual in the Arduino IDE menu:

File > Examples > DecaDuino

DecaDuinoSender

This sketch shows how to use the DecaDuino library to send messages over the UWB radio.

DecaDuinoReceiverSniffer

This sketch shows how to use the DecaDuino library to receive messages over the UWB radio. The received bytes are printed in HEX; this sketch can be used as a frame sniffer to dump received messages.

DecaDuinoChat

This sketch shows how to use the DecaDuino library to send and receive ascii messages via the Serial port over the UWB radio.

Use DecaDuino to implement ranging protocols

DecaDuino can be used to implement Time-of-Flight (ToF) ranging protocols by timestamping frames at transmission and reception. The DecaDuino library comes with a set of sketches that implement popular ranging protocols.

Two-Way Ranging (TWR) protocol

The two example sketchs DecaDuinoTWR_client and DecaDuinoTWR_server propose a simple implementation of the TWR protocol without addressing fields.

Flash each example sketch on two nodes (client and server) and get the distance between the two nodes. The documentation directory contains the client and server state machine diagram.

Symmetric Double-Sided Two-Way Ranging (SDS-TWR) protocol

The two example sketchs DecaDuinoSDSTWR_client and DecaDuinoSDSTWR_server propose a simple implementation of the SDS-TWR protocol without addressing fields. The SDS-TWR protocol implies more messages but is theorically better than the TWR protocol since the clock skew effect is compensated by the symetry of the exchanges.

Flash each example sketch on two nodes (client and server) and get the distance between the two nodes.
