##Accelerometer_ADXL345

This is a high resolution digital accelerometer providing you at max 3.9mg/LSB resolution and large ±16g measurement range. It's base on an advanced 3-axis IC ADXL345. Have no worry to implement it into your free-fall detection project, cause it's robust enough to survive upto 10,000g shock. Meanwhile, it's agile enough to detect single and double taps.It's ideal for motion detection, Gesture detection as well as robotics.

Note:

This library is used for Seeed graphical programming Project only.

API

Initialize:

void init();  // should be called before read data

Read data

/* 
 * Function Name: AxisDigitalAccelerometerRead 
 * Input: PinName, useless, can be any value 
 *        _xyz – chanel choose 
              'X' - read acc_x 
              'Y' - read acc_y 
              'Z' - read acc_z 
 * Return: distance in cm   
 */ 
float AxisDigitalAccelerometerRead(int PinName, char _xyz);

Test Case

Get acc of X, Y, Z in turn, and print to Serial monitor.

    Serial.print(ax, 2); Serial.print('\t'); 
 
    Serial.print(ay, 2); Serial.print('\t'); 
    Serial.println(az, 2); 
     
    delay(20); 
}
