javascript

[John Wiseman]

Has anyone added or considered adding support for Javascript?  People are already running javascript on AR.Drones, it would be nice if they could speak mavlink easily.

That's great to hear.  Do you have a github repo?

FYI you might be interested in http://www.voodootikigod.com/nodebots-the-rise-of-js-robotics and #robotjs on freenode.

Hi,

I've implemented a Python generator that implements a Node.js module for MAVLink.  At this point, I've only tested the generated v1.0/APM code, but it's successfully decoding packets from a real system.

I'll be issuing a pull request back to the main MAVLink repository when the work is bit farther along.

Here's the work in progress: https://github.com/poker-flat/mavlink/tree/node-mavlink

The Javascript generator file dwells in the pymavgen/generator directory, with the node module stuff in the pymavgen/generator/javascript dir; there's a deficient but well-intended readme there, as well, to sketch how to build & run tests.

I'm continuing to work to finish an initial implementation (CRC calc isn't right, etc), make my initial transliteration into more idiomatic and well-performing Javascript, and to figure out a sane way to npm-ify it so it's handy to include in other code.

Your link is well chosen, node-serialport is exactly what we're using in a prototype GCS to interface with an APM via xbee to provide to the MAVLink decoder.  Using Now.js, we've got a bunch of web clients kept in sync, more or less in real time, with a stream of incoming MAVLink packets -- pick up the APM and move it around and watch a dashboard update in realtime across machines connected on a local network.  It's a start!  Huge respect to the open-source community for making it possible.

I'll be posting updates as we continue to work on this, and let me know if you have any questions,

- Bruce

Thanks for the github URL, Bruce.

I've been working on a web client GCS, running server-side python that translates mavlink coming in over xbee/3DR radio to JSON.  It sounds like there might be some overlap with what you're doing, in which case you might find some of the code useful: https://github.com/wiseman/mavelous

Just FYI, I've moved our group's Javascript MAVLink repo to a new org on Github (Alaska Center for UAS Integration, ACUASI).

https://github.com/acuasi/mavlink

[becrev...@alaska.edu]

I've opened a pull request on the main mavlink repo that adds a Javascript generator that renders code suitable for use in Node.js.

 

https://github.com/mavlink/mavlink/pull/107

 

Preliminary, but feedback would be appreciated.

Hi,

Thanks for the pull request, I'll go through it soon.
