Radiomaster TX15

[GiulianoDeMicheli]

Good morning, I have just purchased a Radiomaster TX15 and would like to use INAV telemetry. I tried installing the usual version I use on the Radiomaster TX16s, but it does not work. When will compatibility with this new radio be available?

Same here! I received my TX15 today, started migrating from my TX16S MK2 and noticed that this widget didn't work. It's an essential part of my setup, so it would be veryu nice if the devs can adapt it for the TX15 as well. It should be easy, considering that the screen resolutions are similar and the aspect ratio are the similaron both radios. The TX15 just uses a smaller and brigher screen.

You're all most welcome to contribute to the project. Being able to make these changes means having access to a T15. Which means RadioMaster sending one to a developer on this project who has the time and impetus to make it work. Or have a new developer with that radio submit a PR.

@MrD-RC Thanks for getting back! No idea why they haven't sent any to an active developer, makes no sense to me. I bought mine in mid-August... Anyway.

I'm happy to look into it if you can give me some guidance as to where I should have a look into?

At the moment, I don't know anything about coding widgets etc, but I'm willing to give it a go!

Since I have the radio, I could try to make the required changes and then test on my radio before writing a PR for it, is that ok?

Also, the version of ETX that the TX15 comes shipped with is 3.0.0, which is not officially out yet. No idea what's happening on that front, but I have a feeling that this might be related.

On the other hand, Yaapu telemetry seems to work fine! But the Betaflight scrips doesn't work either, not that I have used it a lot tbh.

@MrD-RC The main issue that I can see is a difference in screen resolution:

1. TX16S: 480x272px
2. TX15: 480x320px

I'm not a developer, but if I can contribute in any way to moving the project forward, it would be my pleasure.

TX Companion has an emulator that can be used to test and debug Lua scripts. It will probably give you an actual error message if something goes wrong.

A PR would be great.

UPDATE (and good news):

The script is working if you use the uncompiled version and compile on the radio.

When used in full screen it's not perfect, but it definitely works!

Next, the script has to be adapted for a screen resolution of 480x320px so that it can work in full-screen mode as well.

I'll try to make some changes and I'll let you know how it goes.

If I manage to get comething working (which is highly unlikely at this point), I'll put in a PR!

UPDATE (and great news):

I made it work with the TX15 (and other 480x320px radios) and made a PR about this:

#190

Please let me know if this OK. and if so, please add it to a new release.

PS: the release version is probably going to change, so please adjust it as you find most adequate.
