Raspberry Pi powered in-car infotainment system

Check out my website for more info: http:https://joelzeller.wixsite.com/copilot

Setup:

• Get Kivy: https://kivy.org/docs/installation/installation-rpi.html

• Get Kivy Garden: https://kivy.org/docs/api-kivy.garden.html https://kivy-garden.github.io/

• Get KivyMD: https://gitlab.com/kivymd/KivyMD

• Get Mapview: https://github.com/kivy-garden/garden.mapview

• Get python-OBD: https://github.com/brendan-w/python-OBD

• This should install garden and then recycleview, and that should be enough to get it working

  pip install kivy-garden

  garden install recycleview

• Python Version 2.7.0 is recommended

MapView Required Setup For mapview to work, one program of kivy must be changed to handle an error.

• sudo nano /usr/local/lib/python2.7/dist-packages/kivy/core/image/img_pygame.py
• scroll down to find "image loader work only with rgb/rgba image"
• delete the except statement that starts with Logger.warning('Image: Unable to convert.......') and ends with "raise"

You will need all files and folders placed in a directory on your pi - mine are located at /home/pi/CoPilot

• Setup to autorun on boot like I do or just run main.py

Recommended Hardware:

• Raspberry Pi 2 or 3 – increase the GPU memory to its max setting using raspi-config
• Official Raspberry Pi 7 inch touchscreen
• Set up an RTC to keep time since the Pi won’t be connected to the internet at all times
• Temperature Probe – place probe wherever desired, mine is inside the car
• Bluetooth OBDII dongle for car (for use with performance pages)
• LEDs (Look in code for which GPIO is used)
• If you want to interface with an old radio, hook up relays to the old buttons and connect to the appropriate GPIO pins
• Two push buttons for Hotkeys (Look in code for which GPIO is used)

How to use:

To use developer mode:

• Changing the “developermode” var to 1 turns off things like GPIO, temp probe, and OBD stuff as it doesn’t play nice on a computer other than the Pi.
• Change this var to 0 if you’d like to use all of CoPilot’s features.

To view current temp:

• Make sure "TempProbePresent" variable in code is set to 1 - if not, temp will be "--"
• Tap under time on home screen and bubble will float unto screen showing temp - tap again to hide

To use bluetooth audio:

• Change the MAC address in the code to the MAC address of your device
• Pair your device with the raspberry pi
• It works best if you start audio first and then tap the bluetooth button on the audio screen
• Track data and a progress bar should appear and the play/pause and seek buttons should work
