Arduino Due & Ultimate GPS

Is there any reason the arduino due doesn't run with the arduino due? When I upload a blank code and connect to RX and TX the only way to get anything from the GPS is to hold the reset button down and there it comes. Is it the processor? Any help would be appreciated. The reason I need the due is the ability to use 9 interrupts.
Thank You!

Really hoping to sort this out by sunrise so I'll be watching till we hit the fields with it in the morning...thanks in advance for your input! chris

Post all your info here please.
Connect WHAT to WHAT?
Connect what to TX and RX?
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html .
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks... Tom... :slight_smile:

Your issue description is a non-sense from the beginning:

...the arduino due doesn't run with the arduino due? :o

When I upload a blank code and connect to RX and TX .... :o

A blank code won't output anything ! Plus RX and TX are definitely NOT the right connections with the GPS breakout board.

ok ard I get it..sorry for the typo I have a lot of excitement and a lot to do for a big day. Following the instructions from adafruit:

This is the blank code and by hooking up Tx to Tx and Rx to Rx between the Ultimate GPS and the DUE I don't get the data like it is shown on that page. However, if I hold down the reset button I start getting some of it continuously. I'm going back to this because I simply couldn't get it working following these steps:

There is the clarification and now I'm gonna to wire things back to that point and get right back with a picture.

Basically I need the due to take in the info from Ultimate GPS and send it out using RFM69HCW based on results from an interrupt. ... This is going to another due trying to listen with another RFM69HCW (both 433MHz)

A blank code is a code without any code !!!!!!

Correct Ard, just as in the tutorial I sent a link to. Simply has the void setup() and void loop()

I think I found why the due doesn't work with the Ultimate GPS. Looking in adafruits gps library (adafruit_GPS.cpp) it says only include software serial on AVR platforms and ESP8266.

At this point I'll switch back to the mega and configure my 9 inputs into 6 interrupts. Thanks everyone!
