Analyze the rc modes activation conditions and only process configured entries. Previously the entire possible list was processed even though typically only a handful are configured.
Reduces the RX task processing time by about 25% (~44us to ~33us) with an average setup of 3 modes configured (F405, SBUS). Processing time savings will diminish as the user configures more modes. But typically far fewer than the maximum of 20 will be configured.
Eliminate unnecessary register writes by keeping previous state information and only writing the registers when the related settings actually change. Saves 17 register writes per `clearScreen()` call.
Also fixed character invert flag handling. Previously changes to the flag would only affect subsequently drawn characters and previous characters would remain unchanged. So for static OSD elements it produced an inconsistent state. Now all characters immediately reflect the current state of the invert flag.
Results in appoximately a 33% reduction in processing time for the OSD task at default settings (~31us reduced to ~21us on F405).
It's long past time for this! The vast majority of airmode related support issues we encounter involve people forgetting to enable airmode.
For the tiny percentage that still (mistakenly) believe they don't want to enable airmode, they can disable if they desire.
Adds available profiles and currently selected OSD profile. If the `USE_OSD_PROFILES` feature is not available then the profile count and selected profile will be 1.
Adds OSD stick overlay radio mode. A zero value indicates OSD stick overlay is not available.
Preserve gyro/acc alignment backwards compatibility for configurator versions unaware of the revised sensor alignment scheme.
Update MSP to add support for:
1. Flag to indicate whether `USE_MULTI_GYRO` is available
2. `gyro_to_use`
3. `gyro_1_sensor_align` and `gyro_2_sensor_align`.
Added features to the BEACON ledstrip profile:
Added a `ledstrip_beacon_color` to allow color selection rather than forcing to white.
Added `ledstrip_beacon_period_ms` to configure the blink period in milliseconds. Smaller time periods mean faster blinking.
Added `ledstrip_beacon_percent` to configure the "ON" time duty cycle. User can set to 100% to have the beacon display a solid color. 0% can be used to turn the becaon completely off.
Added `ledstrip_beacon_armed_only` to allow the user to configure whether the beacon is only on when armed.
Added `ledstrip_visual_beeper_color` to allow configuration of the visual beeper color.
Added the new parameters to the CMS menu.
Simplified the code and combined the RACE and BEACON profile processing.
Added support for auutomatically displaying a beacon that indicates RX_SET or failsafe regardless of the other RACE or BEACON settings.
