Flipper Air Mouse

Brief

"You can turn anything into an air mouse if you're brave enough"

— Piper, a.k.a. Pez

Naturally, the quote above applies to Flipper as well.

The app allows you to turn your Flipper into a USB or Bluetooth air mouse (you do need an extra module, see the Hardware section below)...

Using it is really simple:

Connect the Flipper via a USB cable and pick USB, or pick Bluetooth and pair it with your PC;
Hold the Flipper in your hand with the buttons pointing towards the screen;
Wave your Flipper like you don't care to move the cursor;
Up button for Left mouse click;
Down button for Right mouse click;
Center button for Middle mouse click;
Left and Right buttons for scrolling;
Use calibration menu option if you notice significant drift (place your Flipper onto a level surface, make sure it doesn't move, run this option, wait 2 seconds, done).

See early prototype in action.

The custom module is using Bosch BMI160 accelerometer/gyroscope chip connected via I2C.

Take a look into the schematic folder for Gerber, BOM and CPL files, so you can order directly from JLCPCB.

Original idea:

Expectation:

Reality:

The code is based on the original Bosch driver and an orientation tracking implementation from the Google Cardboard project

If you're familiar with Flipper applications, start in the firmware checkout folder and do the following:

cd applications/plugins
git clone https://github.com/ginkage/FlippAirMouse
cd ../..
./fbt fap_air_mouse

If you're not familiar with those, just grab a fap file from Releases.

TL;DR: Use the code however you want, give credit where it's due, no warranty of any kind is provided.
