DigitalTwins (DRAFT)

PoC

TUTORIAL:

Tutorial

USAGE:

SIMULATE:

The webthing is served and can be queried using http client

git clone https://github.com/rzr/twins ; cd twins
make start

url=http://localhost:8888

curl ${url}/properties
#| {"torso":0,"shoulder":0,"arm":0,"hand":0}

curl -X PUT -d '{ "arm": 42 }' $url/properties/arm
#| {"arm":42}

Then twin can be visualized using:

Next the device can be connected to mozilla-iot Gateway

CLOUD:

url=https://twins.glitch.me
curl -X PUT -d '{ "arm": 42 }' $url/properties/arm

PHYSICAL:

STM32F7 based MCU is running webthing-iotjs with IoTjs for NuttX (until TizenRT is supporting this board).

More details soon:

For instance target

url=http://192.100.0.243:8888
curl -X PUT -d '{ "arm": 42 }' $url/properties/arm
curl -X PUT -d '{ "arm": -42 }' $url/properties/arm

MORE:

LOST ?

Check Concept page for overview, Gateway to get started, IotJs page to install runtime to build webthing as explained in Home page.

For further experiments check Social and Sensor, or Extra parts like WebApp (for Tizen or PWA) or MCU info about running on other microcontrollers not supported by TizenRT.

While Home focus mostly on using iotjs to build webthings (on GNU/Linux or TizenRT for ARTIK05X devices).

FEEDBACK: WELCOME

This document is still in draft state, but reviews are always welcome, if you try to replicate it and stuck on missing instructions I would appreciate that you file issues or even better make pull request (just edit in github) that insert "TODO marks" in following chapters, like:

  • TODO: please explain more this chapter and then remove this TODO line

Community contributions are welcome at:

Support is also possible, ask in:

DISCLAIMER:

WARNING: Developement branches could break over time.

Instead of maintaining "quick and dirty" demo code, I decided to split demo in smaller independents parts (which can reused) and I am upstreaming the most I can.

Then support can be done on mainline branches (or released versions).

Note that, Upstreaming can be a slow process, so snapshots links will remain until 100% of code is upstreamed.
