IRC Ghost 12 bit support

[daleckystepan]

Summary of changes:

• Add 4 new frames with scaling that supports up to 12bit resolution (currently it transfers 11bit -1024:1024 as EdgeTx provides)
• Add checkbox in model setup menu to enable/disable new 12 bit mode.
• BF 4.3 and Ghost FW V1.0.5.2+ is needed.

Benefits:

• smoother feedforward
• smoother flight

Fixes:

• truncation errors with old scaling

OpenTx commit about this
opentx/opentx@0b699e6

Thanks @tonycake for support and help. @3djc for OpenTx implementation.

This hasn't turned into a PR for OTX just yet because @tonycake is still finalysing some tweaks, there might still be changes

[pfeerick]

Thanks for the update... would take a while over here anywhere as it needs some devs and/or users with ghost hardware test it before merge ;)

For this PR to be complete, I think we should add some YAML-specific stuff, so that the config is more explicit.

Green light from Tony :)

@daleckystepan

The changes I made introduce a more explicit module configuration:

moduleData: 
   1:
      type: TYPE_GHOST
      subType: 0
      channelsStart: 0
      channelsCount: 16
      failsafeMode: NOT_SET
      mod: 
         ghost: 
            raw12bits: 1

Can I get an update on this status on this PR, as given have zero Ghost hardware inability to test it... is it working for you guys? If so, Given the update by Raphael I suspect it's ready to merge.

[daleckystepan]

@pfeerick It is working for me but I would like to hear that also from someone not interested (independent) in this PR.

[TheIsotopes]

@pfeerick @daleckystepan everything works as it should for me, with #1377 it's perfect.

[pfeerick]

That's enough grounds for me to subject tomorrows nightly users to it for further testing ;)

[daleckystepan]

Perfect
