Hi,
benutze den Arduino Fio und den Sensor LSM9DSO https://learn.adafruit.com/adafruit-lsm9ds0-accelerometer-gyro-magnetometer-9-dof-breakouts/wiring-and-test.
Benutze auch den Testsketch, der auf der Seite angeboten wird, um die Daten des Sensors auszulesen.
Nun habe ich diesen Sketch etwas versucht zu modifizieren, da ich die 5 sekunden lang den Sensor auslesen will und diese im Array speichern will. Nun habe ich gesagt, dass ich jede 100ms ihn auslesen will, müsste 50mal ausführen, damit ich 5 sekunden daten hätte.
Habe dies anhand einer For-Schleife realisiert, doch es sind mehr als 5sekunden bis er alle werte hat woran kann das liegen?
Hier nochmal die Funktion, die ich geschrieben habe:
void secBuffer()
{
//for loop, 50 because every 100ms I read so in 1sek = 10 values --> 10Values*100ms
// save 5secondes to analyse if static or dynamic + these data is needed to analyse in the 3.Phase
//if lying position intentional or not
for (int count = 0; count < 50; count++)
{
/* Get a new sensor event */
/*These events should be called in the for-loop*/
/*so that u have every 100ms/every measurement actual data*/
sensors_event_t accel, mag, gyro, temp;
lsm.getEvent(&accel, &mag, &gyro, &temp);
// -y = g
/*Problem: When y = g(9,81m/s²) sensor has value > 9.81 so calibration
to 9.81m/s² & other axis to 0.00m/s² -> y shos down -> -9.81
y < 0 && abs(y) > 9.81 is for -y = g

if (accel.acceleration.y < 0 && abs(accel.acceleration.y) > 9.81)
{
accel.acceleration.y = 9.81 * (-1); // *(-1) to have negative value because z shows down
accel.acceleration.x = 0.00;
accel.acceleration.z = 0.00;
}
// y=g
/*Problem: When y = g(9.81m/s²) sensor has value > 9.81 so calibration

{
accel.acceleration.y = 9.81;

}

}

}
Kann mir da jemand helfen, woran das liegt?
