v0.9.0

Adds rec_pb_enabled configuration option.

If this option is set to TRUE, then recorded OSD data (from rec_enabled) will be played back in the goggles using the builtin playback functionality.

No air unit upgrade is required, just along for the ride.

Thanks @Knifa

v0.8.0

This enables "True HD" mode in Betaflight, without the use of FakeHD.

Note that True HD mode in Betaflight requires a Betaflight 4.4 and Configurator build from after December 4, 2022.

True HD will be enabled by default in Betaflight 4.4. Simply connect your AU/Vista to the FC and pick MSP VTx + DisplayPort as the Ports type. You may also need to manually use set osd_displayport_device = MSP in the Betaflight CLI still.

You should see your Configurator switch into "HD" mode where you can drag elements wherever you would wish on a full 60x22 canvas, going all the way out to every edge of the display.

FakeHD will automatically disable.

If you don't want to use True HD mode in Betaflight 4.4, because you want FakeHD still for some reason or you prefer the larger, old font, set disable_betaflight_hd on the wtfos VTx side.

While there is a new Goggles version included, it's only for consistency and contains only code efficiency / formatting changes. Everything should be fully cross compatible and you only need to upgrade the Vista/AUs which you wish to use with Betaflight 4.4 HD mode.

v0.7.2

Goggles only.

Fixes fakehd when used with the new compressed transmission.

v0.7.1

Fixes an issue with recording the OSD to SD while the new compressed mode is enabled.

No new airside, 0.7.0 remains the latest airside.

v0.7.0

LZ4 Compression (#79)

Add a new configuration option, "compress_osd", to the air side process.

If this is set to "true", then the entire "character buffer" will be sent using LZ4 compression at the rate defined in osd_update_rate_hz, instead of sending raw MSP messages over the air.

When enabled, this should fix INAV delta update related issues as well as provide better link stability.

To enable:

Use the CLI button in the configurator on your VTx side after updating to 0.7.0.

package-config set msp-osd compress_osd true
package-config apply msp-osd

If the apply hangs, just reboot your VTx.

Note that INAV HD mode sync issues may still be present, use the usual workarounds (enter menu or switch screens) to fix these.

Compressed mode may also be valuable for other FCs, as it should make the overall link much more reliable and stable.

The goggles side is backwards compatible, so you can continue to use un-updated VTx, they just won't get the new feature.

v0.6.12

Fix an issue in v0.6.11 that could cause display flickering for some users. (note - not the fix for INAV artifacts yet, just a separate "shimmering" appearance caused by rapid redrawing).

No new airside so no need to update all of your VTx units, stick to 0.6.11 there. Goggles only.

v0.6.11

• show_au_data fixed, and should now work without an FC.
• "toast" messages will appear with quick information about connection status. If you hate these for some reason, you can disable them using the configuration (see readme).
• Can record MSP data to the SD card, but no renderer is ready for release yet.

Airside upgrade is not required, but there is new airside code due to code refactoring, so a new version is provided.

v0.6.10

• New, configurable FakeHD row/column setup, see README.
• Configuration options which are not set default to FALSE, not TRUE. See README for configuration options.

Airside upgrade is not required, but there is new airside code due to the configuration options fix, so a new version is provided.

v0.6.9

Added support for KISS Ultra to Flight Controller detection. Thank you to @fedorcomander !

KISS Ultra fonts are named with _ultra_ in the file name.

This release updates the goggles only, the air side remains at v0.6.8.

For documentation about automatic FC-based font selection, please see the README:

v0.6.8

** Alert **

Semi-breaking changes:

• You must rename your custom fonts on the Goggles SD card to match the directory structure seen here for proper functionality.
• The "new" functionality requires an upgrade to the air-side before it will work, but won't crash and won't kick in until you upgrade the air-side. That is, if you just upgrade your goggles, the old functionality will remain. So, don't upgrade your AU/Vista until you are ready with renamed fonts. This is intended to catch as few people out in the field as possible - you really shouldn't be updating in the field anyway, and hopefully most people aren't updating both sides.

In this PR, we use the MSP Variant command (command 2) to retrieve the "variant" reported by the Flight Controller (INAV, BTFL, or ARDU).

Then, we use the variant to pick a font, like so:

font_controller_resolution_page.bin

So for example:

font_bf_hd.bin will be an HD (for use with FakeHD or Ardupilot in Betaflight emulation mode with HD turned on) font with the Betaflight character set.
font_inav_hd.bin and font_inav_hd_2.bin would be a set of HD fonts for use with iNav.

Fonts are searched for in the following order:

• SD Card
• /opt installed path in goggles.
• /blackbox

If a font matching the desired flight controller can't be found, msp-osd will fall back to the default font name (font_hd.bin or font.bin .).

Please see the fonts directory for a complete font directory layout. Copying this structure in the root of your SD card will let you customize each font for each FC as you would like.
