We’re pleased to announce that Hudiy version 1.8 (Bookworm) and 2.4 (Trixie) are now available. You can find the release highlights below:

Android Auto

• DRM rendering:
  We've introduced memory swapping to the DRM renderer for Raspberry Pi. This results in lower projection latency and reduced memory usage during video rendering.
• Keyboard shortcuts:
  We fixed an issue with keyboard shortcut support in Android Auto.
• Day/Night:
  We added the option to independently control Day/Night mode in Android Auto. The mode can now be changed via settings or using the API (https://github.com/wiboma/hudiy/blob/ma ... ayNight.py).

Splash
We have added support for the GIF format in the Splash application, enabling the use of animated logos.

ELM327
We improved communication with the ELM327 devices (both Bluetooth and Serial). Responses are now processed faster, reducing communication latency.

API
Due to the previously mentioned independent control of Day/Night mode in Android Auto, we added a new message: MESSAGE_SET_ANDROID_AUTO_DAY_NIGHT_MODE and updated the API version to 1.1. The API remains backward compatible; however, please remember to update the API in your extensions to utilize this new functionality.

---------------------------

You can download and install the update using the updater program – https://github.com/wiboma/hudiy/blob/ma ... d#updating

A description of all new features and configuration options is available on our GitHub in the updated documentation – GitHub.

Since version 1.8 requires updating Raspberry Pi OS Bookworm to the latest release, we recommend making a full system backup beforehand – just in case.
That way, you can easily revert to the previous state if any operating-system-level issues arise.

---------------------------

Before running the updater, if you’ve changed the system locale, please make sure the Character Set is set to UTF-8.
It seems that when changing the language, Raspberry Pi OS may set the character set to ISO, which can cause display issues and prevent programs (including the updater) from working correctly.

You can change the Character Set in: Start → Preferences → Raspberry Pi Configuration → Localisation tab → Locale → Character Set

it should automatically update?

Updating process is described on our GitHub at https://github.com/wiboma/hudiy/blob/ma ... d#updating. You need to execute the updater manually.

Updates are performed version by version (e. g. 1.0 -> 1.2 -> 1.4 -> 1.6 -> 1.8 for Bookworm or 2.0 -> 2.2 -> 2.4 for Trixie).

You can check current version in Menu -> Hudiy -> Settings -> About.

Great!! I'm at 1.2 as I'm still putting and testing the custom design hat hardware together. Should I go straight to Trixie for Pi5 or stay with Bookworm?? I want it to be compatible to pi4 system too. What benefit in usingTrixie?

Bookworm OS now only receives security updates from the Pi Foundation. If you care about newer package versions and a newer kernel, we definitely recommend Trixie - it is currently the actively developed OS version by the Pi Foundation.

From the Hudiy perspective, the only differences so far between the Bookworm and Trixie versions are Bluetooth cover art and the hotspot with an 80 MHz channel.

Hi, I'm glad that we're now able to set animations for splash screen. However, GIF format is... a bit limited I would say. Is there any chance for being allowed to play video for example in MP4/AVI format in future releases?

Thank you for the suggestion. You can convert an MP4 file to GIF using tools like ffmpeg. According to our observations, the conversion results are quite good (in terms of quality and frame rate). The advantage of using GIF is that it does not require initializing the video decoder. The splash screen is displayed from the moment the window compositor starts until Hudiy launches. In a worst-case scenario (e.g., with a slow SD card), Hudiy's startup may take a few seconds. Initializing the video decoder and rendering pipeline would further prolong this process.

Thank you for advising me the ffmpeg tool. Tools that I used before converted MP4 video to GIF with really bad colors (highly visible color banding). I did not tested it yet with Hudiy, but using ffmpeg tool with color pallete option resulted with really good looking GIF on my PC
