Bus Pirate + FSA03 GPS How to:

I have a few projects that I would like to include GPS data in, in the near future. So I went ahead and picked up a nice ublox based GPS. YOu can get it here: I wanted to used it right away. So rather than coding up some AVR C or arduino stuff I decided to use my bus pirate for the job. Here is the settings I used to get it up and going:

Hardware Settings Table:

Hardware Pinout Table
BPv3 to	FSA03 (GPS)
3.3v to	3v
MISO to	TXL
MOSI to	RXL
GND	GND

Mode: UART
SPEED: 9600
Then default everything else:

Bus Pirate v3

Firmware v3.1

DEVID:0×0447 REVID:0×3003 (A3)

So you can see I am getting hex data. Note you can just enter { in the BPv3 command prompt to enable reading from the UART port constantly. However for copy paste issues for this post I chose to issue single byte read (r). Next is to write some arduino or avr code to translate this NEMA standard output to a human readable format. (Yes I know there are libs available however I prefer to learn by doing) So up next Code!
