# 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.
|
||
|
|
|
||
|
|
For more details on the DecaDuino library, get the latest version of the
|
||
|
|
documentation here: https://www.irit.fr/~Adrien.Van-Den-Bossche/decaduino/)
|
||
|
|
|
||
|
|
## 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.
