Key Features
Overview
The Accel 24 Click Board™ is a compact add-on board with an acceleration sensor. This board features the MXC6655XA, a 12-bit three-axis accelerometer from MEMSIC. It allows selectable full-scale acceleration measurements in ranges of ±2g, ±4g, or ±8g in three axes with a compatible I2C serial interface with 400KHz fast mode operation. Alongside low offset and temperature signal with high accuracy, the MXC6655XA also detects six orientation positions, X/Y shake, and shake directions with an appropriate interrupt signal for these states. This Click board™ is suitable for a wide range of information appliances, consumer electronics, household safety applications, and many more.
The Accel 24 Click Board™ is supported by a mikroSDK-compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

How Does The Accel 24 Click Board™ Work?
The Accel 24 Click Board™ is based on the MXC6655XA, a highly reliable digital triaxial acceleration from MEMSIC. The MXC6655XA is highly configurable with a programmable acceleration range of ±2g, ±4g, or ±8g based on MEMSIC's proprietary thermal technology built with a 0.18μm standard CMOS process. It contains no moving sensor parts, eliminating field reliability and repeatability issues; there is no measurable resonance (immunity to vibration), no stiction, and no detectable hysteresis.
The MXC6655XA also eliminates the "click" sounds typically heard in ball-based orientation sensors. The shock survival of this MEMS sensing structure is greater than 200,000g. This sensor provides X/Y/Z axis acceleration signals with a low 0g offset and temperature signals with high accuracy. In addition, it also detects six orientation positions, X/Y shake, and shakes directions.
The Accel 24 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings capable of operating in a standard or fast mode of operation. The acceleration signal is provided in 12-bit output resolution. In addition to communication pins, this board also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, for orientation and X/Y shake detections. The MXC6655XA allows users to be placed in a Power-Down mode enabled through the I2C interface.
The Accel 24 Click Board™can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
