The flight controller implements a number of critical low-level behaviors.

Installing Betaflight Configurator (BFC)

• Follow the instructions on the developer’s website to download the latest Betaflight configurator: https://github.com/betaflight/betaflight-configurator/releases (scroll down for download links):
  

  • macOS: https://github.com/betaflight/betaflight-configurator/releases/download/10.8.0/betaflight-configurator_10.8.0_macOS.dmg

  • Windows: https://github.com/betaflight/betaflight-configurator/releases/download/10.8.0/betaflight-configurator_10.8.0_win64-installer.exe

  • Ubuntu: https://github.com/betaflight/betaflight-configurator/releases/download/10.8.0/betaflight-configurator_10.8.0_amd64.deb

Connecting to the FC

1. Unplug the battery

2. Disconnect the Raspberry Pi from the FC

3. Connect the mini USB cable to your FC and to your base station

4. Run the BFC on your base station

   1. Verify the version on the top left of the black and yellow window popping up. It should 10.8.0 (Sec9465)
      

      

5. Verify the recognized devices in the top right corner. You should see (depending on your OS)
   

   

   
   

6. Navigate to “Options” on the left column and activate “Permanently Enable Expert Mode”

7. Go back to the “Welcome” page

8. Press on “Connect” (top-right corner)

A successful connection will lead to a page looking like this:

Familiarizing with the configurator and FC settings interface

We will explore each setting relevant to the Duckiedrone in detail later. A few high-level observations:

• Find your FC firmware version (top-left or bottom-right)
  

  

• Keep an eye on the FC “CPU Load”. This tells us how much effort the onboard microcontroller on the FC is busy. We should never let it go above 40% with chosen settings, with lower being better.
