Installation

1. Install dependent Python packages:

sudo pip install pynput
sudo pip3 install pynput
sudo pip install picamera
sudo pip3 install picamera
sudo pip install python-can
sudo pip3 install python-can

2. Download the script to you Pi with OpenAuto
3. Move the script to a folder you want. Example:

/home/pi/scripts/

4. Give the script permissions to run/execute. Example:

sudo chmod +x /home/pi/scripts/read_from_canbus.py

5. Edit the upper section in the script to activate the features you want to use. Avaliable options:

• read date and time from dis/fis and set it on Raspberry Pi. Recommended, if Raspberry Pi has no internet connection in the car.
• read reverse gear message from canbus to activate reversecamer. Reversecamera must be connected to Raspberry Pi, not to RNS-E or av-input modules for RNS-E.
• read longpress down left rns-e button near wheel to activate reversecamera manualy.
• control rns-e by reading rns-e button presses. This works on the whole system and not only on openauto pro gui. Im using that in kodi to navigate too (see kodi keymap editor).
• read ignition off message to shutdown the raspberry pi. Should be only relevant if you have permanent power to raspberry pi.
• read pulling key message to shutdown the raspberry pi. Should be only relevant if you have permanent power to raspberry pi.
• if reversecamera is on by gear detection, and forward gear gets detected, turn the camera off with delay. Better for parking situations :-)
• set delay for turning the raspberry pi off after ignition got detected as off

6. Add script as part of OpenAuto services.
