Minimalistic library for motion detection using low cost KXTJ3-1057, 3-axis MEMS accelerometer, low-power, ±2g/±4g/±8g/±16g full scale, high-speed I2C digital output, delivered in a 2x2x0.9mm LGAplastic package operating from a 1.71V–3.6V DC supply.

Interrupt threshold sensitivity is compared to the top 12bits of the accelerometer 8g output value regardless of the resolution chosen:

This value can be anything from 1 to 4095

• i.e 0.0039 (1/256) to 16 g (4095/256)

Interrupt event duration to trigger the interrupt pin is a function of events and Sample Rate:

This value can be anything from 1 to 255

• i.e 5 event_counts / 6.25 Hz = 0.8 seconds

Interrupt non-activity duration to reset the interrupt pin is a function of events and Sample Rate:

This value can be anything from 1 to 255

• i.e 5 event_counts / 6.25 Hz = 0.8 seconds

• Only 8 and 12 bits modes are implemented (14-bit is not);
• Only non-latched interrupt is implemented;
