Standby Attitude Module (inspired by the MD302 and Garmin G5)

[lilac jackal]

Hi Everyone, I am finally ready to share my next community device, a standby attitude module inspired by the MD302 and Garmin G5. The custom firmware runs on ESP32 S3 for better performance. Please find the build guide here: https://github.com/savesabanal01/Mobiflight-StandbyAttitudeModule-ESP32-S3/tree/StandbyAttitudeModule-release/Instruction Manual.
Here is a video of it working with X Plane:

Thank you to @gritty storm for making the firmware work for ESP32 S3!

@lilac jackal Many thanks for your tutorial. Good job. That will help me

[gritty storm]

@lilac jackal Could you please tell me what the range of values for pitch and roll is coming from the sim?

[lilac jackal]

@gritty storm from the sim, it does not really matter how much the value because the attitude indicator is designed to roll indefinitely and pitch indefintely as well. But I 've tested it with a pitch of around +-45 and roll of +-45 degrees from the sim.

[gritty storm]

So the sim sends +/- 180 degrees, not scaled to another range. Thanks

@lilac jackal I had a rough look into your code. Is this intended:
-DMF_CUSTOMDEVICE_POLL_MS=10 ; time in ms between updating custom device This will update your custom device every 10ms, not faster. I think for this device it doesn't matter as the TFT update takes longer. But maybe for other devices 😉

[lilac jackal]

@gritty storm Yes, that is uncommented in the xxx_platformio.ini file.

I’ll see how it performs if I take it out. Remember, I’m a very amateur programmer so my code is not efficient, LOL🤣

Could I use this with G1000 planes and Boeing/Airbus airliners? I'd use it as the main instrument, like the centre of a PFD or G1000.

Why? because I don't like zooming in with a mouse to see the PFD, lose spatial awareness, then zoom out to fly again.

[lilac jackal]

Yes, you can. It just takes the data from the simulator and renders it on the display so you can use it with any plane.

[balmy cloak]

Thanks, would I have to modify anything for 38000ft or Mach speeds?

[lilac jackal]

The speed is only in Knots, so it will just display the speed in Knots equivalent of Mach speed I suppose. I am not sure if there is a different dataref in X plane or variable in MSFS for Mach speeds. I just currently get the airspeed in knots. For altitude, there is enough space to display 5 digits so 38000 ft should be displayed just fine. I hope that makes sense.

And the airspeed has only space to display 3 digits so upwards of 1000 knots might not be displayed correctly.

[balmy cloak]

Mach speeds can be 2 or 3 digits like ".715". So it will fit and Mobiflight can sense Mach speeds.

[lilac jackal]

Ok then it can be displayed but the units will still say “KNOTS” because that is hardcoded in the graphics. 😀

[balmy cloak]

Which file contains "KNOTS"? I did a search and could not find it - with C++ code it will be easy to switch to MACH.

[lilac jackal]

It is hard-coded in the background graphics itself (not in the C++ code, so you can't see it). I can make a version that says "MACH" later when I return from vacation, but for the moment, please play around with the current version.
