In Topic: Adafruit Ultimate GPS shield

26 May 2015 - 06:08 PM

Hi Netduino Community,

I got to assemble the Adafruit GPS shield to my Netduino Plus 2, and got to print the gps output to the debugger. I am using serial port (COM1) to capture NMEA sentence that VS 2013 prints out on its debugger interface.

How I did it? I assembled the GPS shield on top of the Netduino with all the pins. I solder a pin to Pin 0 and TX on top of the GPS shield and connected these two pins. I ran the code suggested by Bob Cravens Tutorial and was able to print the GPS sentence to the Debugger.

My idea is to be able to capture the NMEA sentence on my computer so I can use the information to code other functionalities. Though, I am having difficulties getting Netduino to send the NMEA sentence to my computer using a COM port, so I can capture it using desktop code or a hyperterminal interface.In my computer Device Manager Netduino appears as using an USB port but not as a COM port. Is this the reason way the hyperterminal dose not capture the NMEA sentence?

Dose anyone know how to solve this issue?

Thanks Gustavo

Chris,
Thanks for your responses and help.
Sorry, my mistake is not O2 I meant D2 or Pin 2
I am using Bob Cravens Tutorial and following the bellow instructions:

• TX (Digital I/O Pin 0) – This is the transmit pin, data that comes from the GPS module with location data.
• RX (Digital I/O Pin 1) – This is the receive pin, data that goes to the GPS module to configure it.
• PWR (Digital I/O Pin 2) – This pin is connected to a transistor that controls power to the GPS. When this pin is set to LOW the GPS module turns on and when the pin is set to HIGH the GPS turns off.

Should I assemble the Shield over the Netduino and make all the existing pin connections between the Shield and Netduino, or have them side-by-side and only make these three connections.

Chris,

 

This is my understanding of the connection:

Netduino         Connect to       GPS Shield

Digital I/O                                   Shield Breakout

Pin DO ---------------------------   TX

Pin D1  ---------------------------   RX

Pin O2  ---------------------------  Power (what pin on the shield will this be?)

The code show supplying power to the GPS through Pin O2. Does this mean that Netduino will supply power through a Digital I/o pin? Also, if this is correct, what will be the pin in the shield to connect to?

 

Thank you,
