UCFK4 Barn Door Tracker

=======================

A [barn door tracker](http://en.wikipedia.org/wiki/Barn_door_tracker) to aid the photography of astronomical objects.

Hardware

--------

This program is specifically designed for use with a UCFK4 (University of Canterbury Fun Kit 4) and a 28BYJ-48 stepper motor.

Full setup instructions

-----------------------

**1. Download and install git and the AVR compilation tools:**

  * gcc-avr

  * binutils-avr

  * avr-libc

  * dfu-programmer

On Debian based distributions this can be done with :

```

sudo apt-get install git gcc-avr binutils-avr avr-libc dfu-programmer

```

**2. Add a udev rule.**

  * Create a file called `/etc/udev/rules.d/52-bootloadDFU.rules` with the following contents:

    ```

    SUBSYSTEM=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff0", GROUP="plugdev"

    ```

    This can be done with the command:

    ```

    echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff0", GROUP="plugdev"' \

    | sudo tee  /etc/udev/rules.d/52-bootloadDFU.rules > /dev/null

    ```

  

  * Make sure you are in the plugdev group. If you are not, you can add yourself with the command:

    ```

    sudo usermod -a -G plugdev $USER

    ```

    Log out and log back in so the changes take effect.

**4. Plug in the UCFK4 via usb cable and run the following commands:**

  ```

  git clone https://eng-git.canterbury.ac.nz/mph/ucfk4.git

  cd ucfk4/apps

  git clone https://github.com/lihop/ucfk4-barn-door-tracker.git

  cd ucfk4-barn-door-tracker

  make program

  ```

Using the tracker

-----------------

* The LED matrix on the UCFK4 displays the time (in minutes) that the tracker will run for.

* Use navswitch left/right to adjust the time.

* Press the navswitch to start tracking. The LED matrix will display a countdown.
