Accel 24 Click Board™

Product Code: MIKROE-5336

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.
