Well I am trying to get the min and max values from this data.
If that's all you are trying to do there is a much simpler method that doesn't require an array. Using only 3 variables you can read the accelerometer into x_acc and then compare it to the min and max values. After reading the accelerometer 50 times you will have the min and max.
Be warned, this code is only an example and doesn't stop reading the accelerometer after 50 readings. Also it does not reset the min_acc and max_acc variables for the next set of readings.
static float min_acc = 1000.0; // Start with the maximum value possible from the accelerometer.
static float max_acc = 0.0; // Start with the minium value possible from the accelerometer.
void loop() {
x_acc = read_accelerometer();
if (x_acc < min_acc) {
min_acc = x_acc;
}
if (x_acc > max_acc) {
max_acc = x_acc;
}
}
