[Elecraft] KX3 programming question

[Edouard Lafargue]

   Jindra,

   Very happy to see yet another chrome packaged app coming up! You can
check how it is done on my existing KX3 rig controller (Chrome packaged app
too ) at http://wizkers.io/ or https://goo.gl/DgLqXH . No need to reinvent
the wheel, it's all already implemented, and all open source (AGPL)  ;-)

    The code you probably want to see is there:
https://github.com/wizkers/wizkers/blob/release/server/www/js/app/instruments/elecraft/display_live.js
where I manage a proper transmission buffer that makes sure you will
transmit and receive everything with no loss. Be careful that since Wizkers
is open source under the AGPL, your own app will automatically become open
source if you reuse any of this code... Do you have a link for your app?

    If you like this existing project, you are more than welcome to
contribute! Wizkers already supports cool features like rigctld support,
Piglet support, etc...

73 de Ed, W6ELA
