Sure GPS Demo Board GP-GS010

[marks]

It seems everyone's gone GPS mad at the moment so I thought I'd try one only $35 delivered.

The GPS is conveniently powered from the mini USB port
when data is received from a satellite a blue led will pulse every second
and 8 different messages are sent out at 9600 baud.
$GPGGA, $GPGLL, $GPGSA, $GPGSV,3,1, $GPGSV,3,2, $GPRMC, $GPVTG

It was easy just hook up an axe132 so I thought ?
Eventually worked out activity was on the GPS_Datain TP7 ,on the board I received. we need to connect to this.
It seems the data pins are crossed proberly why it doesn't come with any header pins which I had to solder on.
I can just imagine all those magic comments from Dippy !!

Now we can run our code. it should display perth time in the terminal.
to see the $GPRMC message just uncomment this was chosen becuase it seems to be the only one that has the date.

#picaxe 18m2  'version 2.D
#terminal 9600

You can also test the GPS board without connecting the axe132.
You need to install a driver for the onboard USB here's a link to find the latest driver
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
version 6.6.1 for windows 7 and others.
Once installed checkin Picaxe/options/serialport
and select Silicon Labs
you can view all messages from the GPS in the terminal...
