Lsm303 read data

[Corci]

hi, i'm Vincenzo, an electronic engineering. I'm realizing a work about LSM303, accelerometer and magnetometer, I've to work with Arduino and Labview: can someone help me with the implementation of the .vi to read acceleration data and magnetic field data into two graphs?

Thank you for the answers.

Hi Vincenzo,

I can send you a typical example to read an analog input from Arduino with Labview through "NI Labview Interface for Arduino Toolkit". Starting from this example you'll can modify it for your purpose. Have a good time!

Thank you so much. I'll try to learn how to use these two powerful instruments, Arduino and Labview.

I wish I can ask something else if I'll need it!

Best regards.

Hi! Working and studying various documentation about this sensor, I've found a sketch for Arduino. I've a question: why getLSM303_accel and getLSM303_mag functions are realized in two different ways? I would understant to be able to interpretate this code. These are the function:

void getLSM303_mag(int * rawValues)
{
  Wire.beginTransmission(LSM303_MAG);
  Wire.write(OUT_X_H_M);
  Wire.endTransmission();
  Wire.requestFrom(LSM303_MAG, 6);
  for (int i=0; i<3; i++)
    rawValues[i] = (Wire.read() << 8 ) | Wire.read();
}

void getLSM303_accel(int * rawValues)
{
  rawValues[Z] = ((int)LSM303_read(OUT_X_L_A) << 8 ) | (LSM303_read(OUT_X_H_A));
  rawValues[X] = ((int)LSM303_read(OUT_Y_L_A) << 8 ) | (LSM303_read(OUT_Y_H_A));
  rawValues[Y] = ((int)LSM303_read(OUT_Z_L_A) << 8 ) | (LSM303_read(OUT_Z_H_A));

I thought to realize in egual ways these void.

Thanks, regards

How is your question related to LabVIEW? Shouldn't you be posting to an Arduino forum?
