GPS in NETMF
Tuesday, May 22nd, 2012
Recently I started a little side project for my fiance to create a Pipboy. The first 2 things she wanted was to be able to send/receive text messages and view her position on a map like in Fallout. The first was done easily enough with a WiFi card and a web-service. The second meant finding a GPS that would work without breaking the bank.
While searching for the right module I came across the Adafruit Ultimate GPS. This module was only $40 plus shipping and seemed to have everything I was looking for, and even a bit more. So I ordered one up and had it sent out.
The module did not disappoint. As soon as I connected power it started spitting out data over the serial port. And the number of samples, along with the PDF doc for the module itself allowed me to start parsing the message in minutes. Soon, I was over on Google Maps pulling down images for my area, modifying them and plotting coordinates.
I took points for each corner and used those to plot my position inside of the map. In less than a days work I had every message decoded and a nice little interface going.
If you're in the market for a NETMF GPS, I highly recommend this module. In fact, I've even taken the driver I created and uploaded it as open source for you to use so you can get started even faster than I did.
