Do you have SmartAudio protocol code extracted for Arduino.

Or a library for that.

I plan to connect simple arduino Nano to arducopter via passthrough PWM and control the vtx with the Nano borad.

(Or the new Arducpter 4.0 onboard scripting)


could you pls remind me - your implementation was able to control recording and photo/video switches on RunCam devices, right? were you able to associate this activity of your smartaudio implementation with the RELAY_PINx configs in ardupilot, so it could be possible to actually map camera control for RunCam from Taranis channels?


PS. i just read comments in the PR - so, is this whole effort pretty much dead now? damn, i just got back to it all with a hope to put a spare RunCam on the plane i intend to build. too bad, too bad indeed.


I dont think there is anything useful in the docs for this situation - its all in the code. The CRSF code has an inbound test which you can see, but not an outbound test - which is what you want. I was planning to write one of these for CRSF but not got around to it.


You should hear this only once after powering your system or when you set a new video channel/ power for less than a second.

There were systems out there who sent the smartaudio command again and again which resulted in unnecessary annoying clicking noise in the audio stream. This might be OK if you don`t need audio at all but that`s not the idea of "Smart" "Audio* :)

In such a case please contact the supplier of your smartaudio control device and kindly ask them to update they`re firmware :)

The 2022 study compares the most recent survey results with the 2017 Smart Audio Report, and also revisits families who were interviewed in 2017, creating a comprehensive picture of the changes over the last five years.



The findings were presented in a webinar hosted by National Public Media (NPM) VP of Sponsorship Marketing Lamar Johnson and Edison Research VP Megan Lazovick and is available now at npr.org/smartaudio. Main findings from the study include:
