Downloaded and installed libraries listed at https://www.pololu.com/product/2470/resources (L3G Arduino library, LSM303 Arduino library and LPS Arduino library)
Using the following example code and I got "Failed to detect and initialize IMU!" from serial monitor.
The sensor outputs provided by the library are the raw
16-bit values obtained by concatenating the 8-bit high and
low accelerometer and gyro data registers. They can be
converted to units of g and dps (degrees per second) using
the conversion factors specified in the datasheet for your
particular device and full scale setting (gain).
Example: An LSM6DS33 gives an accelerometer Z axis reading
of 16276 with its default full scale setting of +/- 2 g. The
LA_So specification in the LSM6DS33 datasheet (page 11)
states a conversion factor of 0.061 mg/LSB (least
significant bit) at this FS setting, so the raw reading of
16276 corresponds to 16276 * 0.061 = 992.8 mg = 0.9928 g.
Serial.println("Failed to detect and initialize IMU!");
snprintf(report, sizeof(report), "A: %6d %6d %6d G: %6d %6d %6d",
imu.a.x, imu.a.y, imu.a.z,
imu.g.x, imu.g.y, imu.g.z);
Using I2C-Scanner from http://playground.arduino.cc/Main/I2cScanner, the serial monitor shows:
I2C device found at address 0x1D !
I2C device found at address 0x5D !
I2C device found at address 0x6B !
Any help would be appreciated.
