Raspberry Pi GPS and LCD

Building upon the I2C and OLED from my previous posts, I connected a GPS and used the same OLED to display data. Currently, latitude, longitude, speed, and course are the values I chose to deal with first, but gpsd has much more data you can get at. I chose to do all my development with C++, but a quick google search shows many examples using Python. Once I get my C++ code working and finalized, I'll port things to Python.

The OLED is connected via I2C to the Raspberry Pi and the GPS is using the hardware UART on the Pi. The hard part is now out of the way! Next up, save the GPS data (in KML) to a file and plot that file on Google Earth.
