Follow the build logs for all the details.

To recap, the source code is here:

• A USB projector supported by libam7xxx is needed, like the Acer C110 or a Philips PicoPix
• Common definitions for BeagleBone device-trees.
• The device-tree overlay for the keypad.
• The device-tree overlay for the rotary encoder.
• The OpenSCAD source code for the magnet ring holder.
• The cyclabile source code

All the source I wrote is GPL.

Make sure the device-tree overlays are enabled in /boot/uEnv.txt on the BBB as explained in https://ao2.it/137,

Other dependencies are available in Debian and can be installed with the following command:

$ sudo apt-get install libam7xxx0.1 libturbojpeg0 liblept5

To build the main project on the BeagleBone Black execute the following commands:

$ git clone https://git.ao2.it/experiments/cyclabile.git/
$ cd cyclabile
$ make NEON=1 EQEP=1
$ sudo make enable_service

And then connect the USB projector to have cyclabile start automatically.

The cyclabile software can also be tested on a normal desktop PC, emulating the encoder with the mouse wheel, and using the keyboard for the navigation keypad, try the following command:

$ git clone https://git.ao2.it/experiments/cyclabile.git/
$ cd cyclabile
$ make && sudo make run
