The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I 2C digital interface.
The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 m g/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided.
Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins.
An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

• ADXL345-EP Supports defense and aerospace applications (AQEC). The ADXL345 Development Board is an easy-to-use tool designed to shorten application development time by providing a ready-to-use platform for data collection and firmware development. Animal Crossing New Leaf For Pc there.
The board is pre-configured as a datalogger that can be used to gather data for refining algorithms, tuning thresholds, and generally familiarizing oneself with accelerometer data. Powered by two AAA batteries, the board is completely untethered and integrates seamlessly into portable applications. Logged data is stored on a MicroSD memory card, providing essentially unlimited memory capacity and operating system versatility. Data is stored in a text (.txt) file, so no software installation is required to operate the board or read data. A 2GB MicroSD card and a USB MicroSD card reader are provided with the board. Additionally, the board is fully programmable, providing a hardware platform on which firmware can be tested in parallel with development of application hardware. Communications and processing are performed by an ARM7-based ADuC7024 micro-controller, and firmware is written in C.
