New IMU BerryGPS-IMUv4

[Mark_OzzMaker]

Below is what I did to get it working.
I am sure that sometime in the future this will not be needed as it will be in the main image.

1.  burn the openplotter image to sd card  2020-12-16-OpenPlotter-v2-Starting.img
   
   
2.   enable i2c interface with sudo raspi-config
   
   
3.   open OpenPlotter settings app and install I2C and PyPilot
   
   
4.   the updates need to be downloaded and installed, go to terminal window and enter the below commands;
   
   
   1. sudo apt-get update
      the above may fail, still continue
      
   2. sudo apt-get install libqt4-dev cmake -y
      
   3. git clone https://github.com/seandepagnier/RTIMULib2.git
      
   4. git clone https://github.com/pypilot/pypilot.git
      
   5. cd RTIMULib2/Linux/
      
   6. mkdir build
      
   7. cd build/
      
   8. cmake ..
      
   9. make -j4
      
   10. sudo make install
       
   11. sudo ldconfig
       
   12. cd ../python/
       
   13. python3 setup.py build
       
   14. sudo python3 setup.py install
       
   15. cd ~/pypilot/
       
   16. sudo python3 setup.py install
       run the above command twice
       
5. Open PyPilot, it should now have detected the IMU
