Hi all, I am putting myself down as a newbie for now.
I have been playing around with my Arduinos for about a month now.
I have managed to get a couple of projects type tested and sort of working.
The local Amateur Radio club that I am a member has asked me if I could make a GPS locked clock for the next field day, I said yes its in March the 19th - 20th.
I have some lovely large 7 segment displays size of them is 180mm x 230mm, could read the clock from 100 paces, lol.
Now on to my problem, its going to be a simple error on my part but I have been trying to get a stupid GPS to talk to an Arduino now for 5 days, and are starting to lose it…
Now I have tested the GPS unit, its a ublox unit that outputs data at 9600 bps and needs to be inverted and buffered to correct rs232 levels for a PC to read it, this is no problem works fine.
Talking about rs232 data into the cpu, correct me if wrong the voltage swing for the TTL GPS data should it be 0v - 5v signal or 5v to 0v I have tried it all and the input pin should be the pin 3 on the area marked PWM, right?
The Arduinos are the mega ones 1x 1280 , 1x 2560, I have a really big project latter on thats going to need some space
With the IDE there is a couple of demos, TimeGPS, now with a little code change from 4800 to 9600 it should read the GPS and output the data via the serial port display to right in front of me, NOTHING, zip, narder.
I have check everything at least ten times now and I am ready to say sorry no I am not doing it, plus the talk on these micros no, I normally give very good talks on what ever I am explaining at levels the people can understand.
I was hoping some one might be able to point out what I have done wrong.
If is really the start to many projects that require a gps not only for UTC time but location and height.
I am looking forward to any help, I am to young to have Grey hairs…
Cheers
Paul
