Gyro 7 Click-Board

How Does The Gyro 7 Click Board™ Work?

The Gyro 7 Click Board™ as its foundation uses the ICG-1020S, a high-performance 2-axis gyroscope from TDK InvenSense. The ICG-1020S is highly configurable with a full-scale programmable range from ±46.5dps to ±374dps. The single structure vibratory MEMS rate gyroscope detects the X- and Y-axis rotation. When the gyroscope is rotated about any sense axes, the Coriolis effect causes a detected vibration. The resulting signal is amplified, demodulated, and filtered to produce a proportional voltage to the angular rate. With its 2-axis integration, the Gyro 7 Click Board™ allows you to design it into an optical image stabilization (OIS) application.

Two-axis MEMS rate gyroscope sensor, the ICG-1020S, comes with integrated 16-bit ADCs and signal conditioning with two axes XY configuration. After the signal is digitized, data is processed through a digital filter and output through sensor data registers. Besides, the ICG-1020S is also characterized by high resolution and low RMS noise, noise density, a fast sample rate at up to 32kHz, and low power consumption.

The Gyro 7 Click Board™ communicates with MCU through a register-selectable standard SPI interface that enables high clock speed up to 20MHz, supporting the two most common SPI modes, SPI Mode 0 and 3. Other blocks include onboard clocking, temperature compensation, and bias circuits. The sensor data registers contain the latest gyro data, and they are read-only registers accessible via the serial interface. Data from these registers may be read anytime. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labelled as INT, indicating when a specific interrupt event occurs.

The Gyro 7 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.
