Inclinometer 2 Click Board™

Product Code: MIKROE-5156

How Does The Inclinometer 2 Click Board™ Work? The Inclinometer 2 Click Board™ as its foundation uses the IIS2ICLX, a high-accuracy (ultra-low noise, high stability, and repeatability) and low-power two-axis linear accelerometer with digital output from STMicroelectronics. The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of providing the measured accelerations to the application over a selectable digital interface. Its high accuracy, stability over temperature, and repeatability make IIS2ICLX particularly suitable for inclination measurement applications. The IIS2ICLX has an unmatched set of embedded features (programmable FSM, Machine Learning Core, sensor hub, FIFO, event decoding, and interrupts) and delivers high accuracy and performance at low power. The sensing element is manufactured using a dedicated micromachining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers. The Inclinometer 2 Click Board™ allows using both I2C and SPI interfaces with a maximum frequency of 400kHz for I2C and 10MHz for SPI communication.

The selection can be made by positioning SMD jumpers labelled as COMM SEL in an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. While the I2C interface is selected, the IIS2ICLX allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. This Click board™ also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labelled as INT, indicating the status of the measurement process itself. The hardware flexibility of this Click board™ allows connecting the pins with different mode connections to external sensors to expand functionalities such as adding a sensor hub. When sensor hub mode (Mode 2) is enabled, the I²C master interface for connecting external sensors is available on an onboard header reserved for the Master I2C interface, which is unpopulated by default. The Inclinometer 2 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.
