Linkit One and MMA7660 accelerometer example

The MMA7660FC is a digital output I²C, very low-power, low-profile capacitive micro-machined accelerometer featuring a low pass filter, compensation for zero-g offset and gain errors and conversion to six-bit digital values at a user configurable output data rate. The device can be used for sensor data changes, product orientation and gesture detection through an interrupt pin (INT).

Communication is handled through a 2 pin I2C interface, available on a wide range of microcontrollers. The I2C address by default is 0x4c.

Code

I used this library – https://github.com/mcauser/Grove-3Axis-Digital-Accelerometer-1.5g-MMA7660FC

This is the default example

 

[codesyntax lang=”cpp”]

#include <Wire.h>
#include "MMA7660.h"
MMA7660 acc;

void setup()
{
acc.init();
pinMode(13, OUTPUT);
Serial.begin(115200);
}

void loop()
{

static long cnt = 0;
static long cntout = 0;
float ax,ay,az;
int8_t x, y, z;

acc.getXYZ(&x,&y,&z);

Serial.print("x = ");
Serial.println(x);
Serial.print("y = ");
Serial.println(y);
Serial.print("z = ");
Serial.println(z);


if(acc.getAcceleration(&ax,&ay,&az))
{
Serial.print("get data ok: ");
}
else
{
Serial.print("tiem out: ");
}

Serial.println("accleration of X/Y/Z: ");
Serial.print(ax);
Serial.println(" g");
Serial.print(ay);
Serial.println(" g");
Serial.print(az);
Serial.println(" g");
Serial.println();
delay(50);

}
