Jeff,

Do we have (or can we get) a serial interface in the HXr/Minis we can use to interface/implement with this F4 based AOA tone system (2018 EAA Founders Innovation Prize winner)? First link is the you tube demo of it; the second link is the DIY system that we can build if we have the GRT hooks to do it (they started with Dynon to develop the system). Says they want to work with GRT etal.

Have you guys heard of this?

It should work with the "V-Speed ADS" serial output in the EFIS. I haven't personally heard of it.

Couldn't the tones just be built into the software? We already have audio warning outputs.

...if MORE people ask for it, I'm sure Jeff would move it up the list, but I'll take hooks for now.....the OnSpeed guys have provided the code free on their website....MGL already put it in their code.....

It's just one of our serial output options using the data format for the V-Speed ADS (a visual AOA indicator), which was originally designed for a Dynon data format. Set the baud rate to 115200 and set the Serial Port # Output to V-Speed ADS. We don't fill in all the AHRS data but it looks like the OnSpeed code only needs AOA and airspeed. Our update rate might be different though, and I didn't check to see if that would affect it.
