i2c_restart(); // perform I2C restart

// select sensor in read mode

if (!i2c_write(| SENSOR_ADDRESS | I2C_READ_BIT)) {

// read two bytes of sensor data

data[0] = i2c_read(1);

data[1] = i2c_read(0);

reading = *((signed short *)(&data[0]));

}

i2c_stop();

Here is the pseudo code for accessing the G-Force sensors:

byte data[6];

signed short GX, GY, GZ;

i2c_start();

// select sensor in write mode

if (!(i2c_write(SENSOR_ADDRESS | I2C_WRITE_BIT))) {

// send "read data" command to sensor

if (!i2c_write(0x07)) {

i2c_restart(); // perform I2C restart

// select sensor in read mode

if (!i2c_write(| SENSOR_ADDRESS | I2C_READ_BIT)) {

// read 6 bytes of sensor data

data[0] = i2c_read(1);

data[1] = i2c_read(1);

data[2] = i2c_read(1);

data[3] = i2c_read(1);

data[4] = i2c_read(1);

data[5] = i2c_read(0);
