Hello,

I created a simple sketch for testing a gyro. All worked well and the debugger showed the data correctly.

I selected to STOP the Serial window and now I can no longer run the solution. It appears to build fine, but dumps the following on debug run:

Compiling 'GyroTest' for 'Arduino Mega 2560 or Mega ADK'
Binary sketch size: 7538 bytes (of a 258048 byte maximum) (0.5770662 secs)
Compiling debug version of 'GyroTest' for 'Arduino Mega 2560 or Mega ADK'
crtm2560.o : : In function `__vector_default':

Couldn't determine program size: 



Can anyone help?

Cheers

I cant paste the entire thing in here.

Cheers for any help on this.

Hi Tim,

So oddly enough, I wrote a quick C# app and called the serial port manually to read the data.

When I went back to the gyro sketch with arduino, the sketch now builds and debugging is fine - the Serial window is running data at 9600.

Could this be something to do with the port not being closed or flushed correctly when I clicked on "STOP" on the serial window?

Not sure.

Here is the sketch:

[code]
#include <Wire.h>
#include <L3G.h>

L3G gyro;

void setup() 
{
  Serial.begin(9600);
  Serial.println("Hello world") ;
  Wire.begin();

  if (!gyro.init())
  {
    Serial.println("Failed to autodetect gyro type!");
    while (1);
  }

  gyro.enableDefault();
}

void loop() {
  gyro.read();


    // In following Dividing by 114 reduces noise
  Serial.print("Raw X:");  Serial.print((int)gyro.g.x / 114);   
  Serial.print(" Raw Y:"); Serial.print((int)gyro.g.y / 114);
  Serial.print(" Raw Z:"); Serial.println((int)gyro.g.z / 114);

  delay(100);
}
[/code]

Thanks for the help. Let me know what you need for a repro.

Cheers

Hi Tim,

I downloaded it 2 days ago - version 1.1212.30

Will keep an eye on it and try to understand any future events  a little more

Cheers
