Methinks you are getting "pool" and "poll" confused.
i mean poll data... sorry for my bad english!

Ahh ok. But I think with the Garmin there is no way to poll the data.

You could use a big buffer and then read the buffer out if you need it. This should/could work.

what do you mean by pool the data?

I got the sketch working from the playground. So it does display the data in a
usefull way.
Have you done the same? How fast does the new data appear on the serial?
I always got a 2 second delay...

Yeah it was the Converter from RS232 to a TTL signal. Now it does work, more or less....

I wrote a sketch that shows me the time on a LCD getting the data from the GPS. But the time
on the LCD is just updated every 2 seconds. Bu the data from the GPS is sent every second....
Why is there this delay of one second? Does the data processing take so long?

I used the Code from the Arduino Playground...

Which model Garmin GPS do you have?  What output does it have?  USB?  232?

Its the GPSmap 76s and has a serial output...

Yes it does send the data in the NMEA protocol.
Does someone have experience with Garmin GPS?

hmm ok so how I can check if It's fryed up? (is there an easy way to check this?)

Geko

PS:
But the strange thing is that I sometimes get the "right" data from the Arduino.
Sometimes I could read
$PGRMM,CH-1903*44
$HCHDG,221.7,,,0.7,E*28
but the $GPGGA wasn't there...

Hello

So I got some troubles getting the right data from a Garmin GPS:
First I plugged the Garmin to the PC to get some NMEA Data:

$GPGGA,121638,4724.0053,N,00830.5565,E,1,04,4.0,510.6,M,48.0,M,,*48
$GPGLL,4724.0053,N,00830.5565,E,121638,A,A*43
$GPBOD,,T,,M,,*47
$GPBWC,121638,,,,,,T,,M,,N,,A*74
$GPVTG,222.4,T,221.7,M,0.0,N,0.0,K*4E
$GPXTE,A,A,,,N,A*51
$PGRME,16.8,M,12.3,M,20.8,M*1B
$PGRMZ,1659,f*3F
$PGRMM,CH-1903*44
$HCHDG,221.7,,,0.7,E*28

That was what he sent to me every second.

Now i saw that this line is important:
$GPGGA,121638,4724.0053,N,00830.5565,E,1,04,4.0,510.6,M,48.0,M,,*48

I used the GPS Tutorial on the Arduino Website but without any success.
I just changed the GPRMC to GPGGA and changed some parameters.
I plugged the TX from the Garmin to the Rx und the Ground to the Ground.
But as i started the Terminal nothing readable appeared...
Can someone help me


PS:
even with this code i just get:

void loop(){

  digitalWrite(ledPin, HIGH);        // switch LED on (debugging)
  
  if(Serial.available() > 0){        // send data only when you receive data
    incomingByte = Serial.read();    // read incoming
    Serial.print(incomingByte);      // send incoming
  }  
}

Thx a lot. May you send me the link from the Forum. I can speak German
so it would be easyer for me to read it there.

WOW!

Great! I'm gonna try this for my FPV Plane!
How fast is the refresh rate on the Screen?

??? lol
would be a huge weight with 35km of rope smiley
that's why I connected a Mobile to the Arduino so that the sonde can send me an SMS when it has been returned back to the ground...

I launched now 3 Balloons with an Arduino Mega one to 35km one to 32km and the third up to 28km height and they do still work smiley
