MIKROE Accel 24 Click

Accel 24 Click is a compact add-on board that contains 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. Accel 24 Click in 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 MEMS 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. Accel 24 Click communicates with an 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. This 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.
