Improves menu readability by changing the background from a transparent display of the camera image to a static opaque gray background.
The behavior is controlled with the `osd_menu_background` parameter which defaults to `TRANSPARENT` to preserve the previous behavior. Other opaque options are available:
```
osd_menu_background = TRANSPARENT
Allowed values: TRANSPARENT, BLACK, GRAY, LIGHT_GRAY
```
The background setting is available in the CMS OSD menu and the user can cycle through the various options with the display updating in real-time.
Currently only the onboard MAX7456-based OSD is supported, but the implementation adds `displayPort` support so it can easily be extended to other OSD devices if those manufacturers want to add support. Also can be extended to other background types (like colors, varying transparency, etc.) for future device support.
Makes use of the built-in MAX7456 feature to display all transparent pixels as "gray". The MAX7456 display area seems to be a few scan lines smaller than the actual camera video image so it's normal for some of the camera image to "leak" at the top/bottom of the display. The OSD display area can be adjusted up/down using the `vcd_v_offset` setting if desired.
Function SD_Init() is called as follows:
./main/msc/usbd_storage_sdio.c: if (SD_Init() != 0) {
./main/drivers/sdcard_sdio_baremetal.c: if (SD_Init() != 0) {
./main/drivers/sdcard_sdio_baremetal.c: if (SD_Init() != 0) {
and checks whether return value is != 0, that is != SD_OK.
Previous implementation is working, however, cannot handle proper
SD_Error_t handling. In addition the code was refactored and simplified.
Improve the logic to be table-based and add validation of the rc_rates and expo values. The previous logic only validated the super-rates and the rc_rates can also be out-of-range when changing rates types. The expo values are also checked but currently all the rates types have the same constraints so there's no possibility currently of them being out of range. But this will allow for possible new rates type that have different constraints.
Since version 4.0.0 CLI variables:
* acc_cut_hz,
* accxy_deadband,
* accz_deadband,
* acc_unarmedcal
are removed from settings.c and thus can be also removed
from the CLI documentation page.
Fixes logic errors in #9574
For RACEFLIGHT rates the applicable `case` was missing so the logic defaulted to the BETAFLIGHT rates logic which incorrectly limited the maximum rate value to 100. RACEFLIGHT values range to 255.
For KISS rates the limit was set to 100 but the Configurator constrains to 99.
