The Retro Gauge is a mechanical vehicle gauge that displays data received over a serial communication line. One possible use of the gauge is to display vehicle data from the OpenXC platform.
The design intent was to keep the gauge as open and accessible as possible so that the community could contribute and benefit from the design.

Dependencies
Besides a standard Arduino development environment, the firmware also requires the SwitecX25 library to drive the stepper motor. This library is based on Guy Carpenter's Gaugette project.
Compiling with Arduino IDE
Update the git submodules to pull down the SwitecX25 library:
$ cd retro-gauge-firmware
$ git submodule update --init
After updating the submodules, open the firmware.ino sketch in the Arduion
IDE. In the menu, go to Sketch -> Import Library -> Add Library, navigate to
the firmware folder and import the SwitecX25 folder.
In the Tools -> Board menu, select the Arduino Pro or Pro Mini (5v 16MHz) w/ ATmega328 option.
Finally, hit upload! You may need to manually select the right serial port if you have more than one device connected.
Compiling with Makefile
Update the git submodules to pull down the SwitecX25 library and the Arduino-Makefile project:
$ cd retro-gauge-firmware
$ git submodule update --init
After updating the submodules, compile the firmware:
$ make
and flash the attached gauge:
$ make upload
The Makefile will attempt to automatically determine the name of the attached
port, but you may need to specify it manually with MONITOR_PORT if it doesn't
work. For example, if your device shows up as /dev/ttyUSB1:
$ MONITOR_PORT=/dev/ttyUSB1 make upload
