• move lcd capabilities from firmware to boards
• minor fixes found during testing
• more post ADC refactor fixes
• housekeeping

TODO

• surface radio configuration
• Companion yaml encode/decode own models and settings
• surface radio decode Companion encoded yaml

Add a very brief look, on the simu, the left stick can only be moved horizontally and does steering, good, but the right one that does throttle, is also only horizontal, which makes it really difficult for user to understand which one is which. Could the right one made to only move vertically ?

@philmoz also raised this. Yes it can be re-orientated.

Looking good - will do more testing later.

One thing - button text is clipped slightly on MacOS.

[philmoz]

Reading from radio and writing back to radio seems to work ok. No obvious issues with conversion.

I think the LCD and buttons could be bigger.

I had a look at the LCD code and it seems it could do scaling based on widget size (rather than just x2):

Patch for this (have not tested if it affects other simulators yet):

If we enlarge the lcd then buttons could also be enlarged and widened to take into account each OS font.

[elecpower]

Need to test layout for the new screen size you have been working on for a while so we have the full range covered.

@pfeerick can we get this one in asap to exposed to more testers and opinions plus reduce the complexity of any merge conflicts.

Another PR on a generic sim for all radios would follow including auto resizing to lcd and scale the smaller ones along the lines @philmoz has suggested.

[elecpower]

I'm also considering custom surface widgets for throttle/brake and steering to substitute for the air joysticks. Will need to determine how much effort and float mock up with surface users.

[pfeerick]

If you are happy with this as it is, fine with me :) I'm not able to do much for the next few days on project so won't catch anything more than blindingly obvious issues. Just downloading the PR build now, will merge shortly if nothing immediate jumps out.

[elecpower]

@3djc and @philmoz have performed some checks and nothing stood out. Some other testers this far out from 2.11 release is a good thing to enable time to fix.

Thanks for all the work on this! will test this weekend.
