Tasks Completed:
#

During the ninth week of my Google Summer of Code (GSoC) project, I made significant strides in implementing the CARLA-CAN-File playback feature within the Automotive Grade Linux (AGL) ecosystem. Below, I provide detailed information about the tasks completed, documentation updates, and plans for the upcoming week.

# Successfully built the Demo Control Panel image and tested it on RPi4 and Qemu.
#

This week involved building and texting the AGL Demo Control Panel on actual hardware and testing it’s compatibility with other AGL apps.

# Minor Bug fixes and Refactoring.
#

Fix Playback File selection dropdown not populating when no recorded file is found.
Fix Crash for when playback mode is not specified in config.ini
Started Refactoring the vehicle_simulator module to simulate tyre pressure readings; CARLA does not provide this data vai APIs.

# Code Merged:
#

30049: Add Python Script to Convert CARLA data into CAN messages:

V1:
    - Add carla_to_CAN.py script to convert CARLA data into CAN messages
    - Add README and requirements.txt

V2:
    - Add script to record and playback messages from can interface
    - Fix mappings to agl-vcar.dbc file

V3:
    - Fix playback feature for record_playback.py
    - Update requirements.txt
    - Update README to explain setup and usage of Scripts with CARLA

V4:
    - Add file playback feature to Demo Control Panel
    - Remove dependency on numpy to calculate 
           vehicle speed, use math lib instead
    - record_playback.py can now be imported and also be 
           used in standalone mode
    - Fix: Now data is sent to CAN interface only when it 
           is updated
    - Fix: Delay is now based on previous timestamp
           and not the starting timestamp
    - Fix: Send correct Gear messages, compatible 
           with the agl-vcar signals

30107: Pre-compile resources and remove unused dependencies:

V1:
    - Use rcc to compile qrc resource file on host, and 
      remove post install step to compile on target.
    - Remove PySide6 as dependency for demo control panel 
      as python3-qtwidgets is no longer used to provide 
      toggle button, and pyside6-rcc is not provided.

V2:
    - Replace PySide6 with PyQt6 at the resouce compile 
      step
    - Add dynamic layer for meta-qt6 to provide 
      QtWidgets and QtSvg
    - Update runtime dependencies to provide bash and
      python3-rich for CLI interface
