ADXL345 digital tri-axial acceleration due to gravity gradient module IIC/SPI transmission

Description

ADXL345 is a small, slim, low-power three-axis accelerometer, on high
Up to ± 16 g acceleration for high resolution (13 digits) measurement. Number of digital outputs
According to the 16-bit binary complement format, Via SPI (3-wire or 4-wire), or access I2C digital interface.

ADXL345 suitable for mobile equipment applications. It can skew detection applications
Measure the static gravitational acceleration, and to measure the dynamics of movement or impact causes the effect Speed. It has a high resolution (4 mg/LSB), measuring approximately 0.25 ° tilt
Angle changes. ADXL345 digital outputs, such as the time of acceleration, without the need for
Analog to digital conversion, saves system cost and board space. In addition, the ADXL345 is a small, thin, ultra low power consumption 3-axis accelerometer, resolution (13), measuring range ± 16G. Digital output data for the 16-bit binaries Complement format, accessible through the SPI (3-wire or 4-wire), or I2C digital interface to access.

ADXL345 suitable for mobile equipment applications. It can skew detection Measurements in static gravitational acceleration, caused by the movement or impact can be measured Normal acceleration. High resolution (3.9mg/LSB), able to measure less than 1.0 ° The inclination angle.
The device detection offers a variety of special features. Active and inactive detection capabilities through Compare any acceleration on axis with the threshold set by the user to detect the presence of games Move takes place. Dan Zhen percussion test detects any direction and dual vibration To make. Free fall detection can detect whether the device is dropped. These Features can be independently mapped to one of the two interrupt output pin. Port Dickson Patented integrated storage management system uses a 32-level first in, first out (FIFO) buffer that can be used to store data, which will host processor load Minimize and reduce overall system power consumption.

Low power mode supports intelligent power management based on movement, leading to very low power consumption threshold sensing movement and Acceleration measurements.
