How Does The Smart DOF 2 Click Board™ Work?
The Smart DOF 2 Click Board™ is based on the LSM6DSV16XTR, a high-performance 6-axis IMU with sensor fusion, ASC, MLC, Qvar, and OIS/EIS paths from STMicroelectronics. It features a 3-axis digital accelerometer (±2/±4/±8/±16 g full scale) and a 3-axis digital gyroscope (±125/±250/±500/±1000/±2000/±4000 dps full scale) with a triple core for processing acceleration and angular rate data on three separate channels (user interface, OIS, and EIS) with dedicated configuration, processing, and filtering. It also enables processes in edge computing, thus allowing advanced features, such as FSM and MLC, as AI features for IoT applications. The list continues with embedded temperature sensors, advanced pedometers, step detection, and tilt detection, thus making this sensor a truly smart device.
The LSM6DSV16XTR operates in several modes. Accelerometer power modes have five different modes that affect the unit's performance. Accelerometer dual-channel mode can work with two different scales simultaneously. Gyroscope power modes consist of five modes too, which lets you choose between high performance, high accuracy, and sleep. The list continues with ODR-triggered mode, analogue hub functionality, Qvar functionality, enhanced EIS, OIS, and more. The unit also is equipped with embedded 1.5KB of data in FIFO, with up to 4.5KB with the compression feature enabled. The FIFO allows you to store data about the gyroscope, accelerometer, external sensors, sleep counter, temperature, and more.
The Smart DOF 2 Click Board™ allows selection between I2C or SPI interface at a maximum frequency of 1MHz for I2C and 10MHz for SPI communication. Selection is made by positioning the three SMD jumpers labelled COMM SEL to the appropriate position, with I2C selected by default. The I2C address can be selected via the ADDR SEL jumper, with the jumper positioned on 0 by default. The INT pin on the mikroBUS™ socket is a programmable interrupt pin that generates an interrupt on status events, such as free fall, wake-up, 6D orientation, Click Board™ or double-click, motion, and more.
The LSM6DSV16XTR also offers flexible connection pins with three modes of functionality. Using two three-position jumpers, you can choose between Qvar, Master I2C, and Aux SPI functionalities. The unit has an interface for two Qvar (electrostatic sensor) electrodes for user interface functions, such as tap, double tap, triple tap, long press, swipe, and more. Those two electrodes can be attached to Q1 and Q2 headers, positioned at the top of the board. On the left from the three-position jumpers is an AUX SPI header allowing accelerometer and gyroscope data to be available for OIS applications (camera module, for example). On the right side of the board, there is an M I2C header for connecting external sensors (up to 4), with an additional interrupt INT2 pin, besides standard 2-Wire interface lines SCL, SDA, and GND.
ThSmart DOF 2 Click Board™ e can only be operated 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.
