SDL HMI

HTML5 based utility to see how the SDL works. It connects via WebSocket to SDL Core

Getting Started

This project interacts with SDL Core. To initialize the git submodules in this project after cloning, run the following commands:

cd sdl_hmi
git submodule init
git submodule update

Alternatively, you can clone this repository with the --recurse-submodules flag.

Dependencies

• ffmpeg : sudo apt install ffmpeg
• Python3,PIP : sudo apt install python3 python3-pip
• ffmpeg-python : sudo python3 -m pip install ffmpeg-python
• chromium-browser : sudo apt install chromium-browser

Start HMI

A quick guide to installing, configuring, and running HMI.

1. run `deploy_server.sh`
2. run SmartDeviceLinkCore
3. run chromium-browser [root_of_cloned_sdl_hmi_repo/index.html]

Note that all these 3 steps are foreground processes and block terminal window, so you should use separate terminal windows for all of them.

deploy_server.sh responsibility

External python server is required for :

• simulating Low voltage signals
• transferring audio/video data from sdl_core to HMI in browser
• simulating Policy table update using in-vehicle modem

If deploy_server.sh will not be started this functionality won't work.

Simulating signals for LOW_VOLTAGE feature

* Open the `Exit Application` menu, choose a signal from the menu and press `Send signal`

PTU With vehicle modem

* Click  the `System Request` button
* Select the `PTU using in-vehicle modem` checkbox to enable the feature

Note

SDL HMI utility is only for acquaintance with the SDL project.

Look at configuration file app/FLAGS.js. You can found there:

• SDL WebSocket connection string - WEBSOCKET_URL
• Python WebSocket url for handling signals - PYTHON_SERVER_URL
