Overview
L' Accel 19 Click Board™ est une carte complémentaire compacte qui contient un capteur d'accélération. Cette carte est équipée du LIS2DTW12, un accéléromètre à trois axes hautes performances à très faible consommation d'énergie de STMicroelectronics. Il permet des mesures d'accélération à pleine échelle sélectionnables dans des plages de ±2g, ±4g, ±8g ou ±16g sur trois axes avec une interface hôte configurable qui prend en charge les communications série SPI et I2C. Outre un capteur de température intégré d'une précision de 0,8°C avec des ODR allant de 50 à 1,6 Hz et une résolution de 8 à 12 bits, il dispose d'un moteur interne dédié pour traiter la détection de mouvement et d'accélération.
L' Accel 19 Click Board™ convient à diverses applications telles que les fonctions activées par le mouvement et les interfaces utilisateur, la reconnaissance par tapotement-double tapotement, la détection de chute libre, le suivi et bien d'autres encore.

How Does The Accel 19 Click Board™ Work?
The Accel 19 Click Board™ as its foundation uses the LIS2DTW12, a highly reliable digital triaxial acceleration and temperature sensor from STMicroelectronics. The LIS2DTW12 is highly configurable with a programmable acceleration range of ±2g, ±4g, ±8g, or ±16g capable of measuring accelerations with output data rates from 1.6 to 1600Hz. Multiple operating modes with various bandwidths, low noise, very stable sensitivity, together with the capability of working over a wide temperature range, makes this device particularly suitable for vibration monitoring in industrial applications.
The LIS2DTW12 has an embedded temperature sensor with a typical accuracy of 0.8°C, ODRs ranging from 50 to 1.6Hz, and 8 to 12 bits resolution. Besides, it has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data to limit intervention by the host processor. Alongside these features, the LIS2DTW12 has a dedicated internal engine to process motion and acceleration detection, including free-fall, wakeup, highly configurable single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection, and 6D/4D orientation.
The Accel 19 Click Board™ allows using both I2C and SPI interfaces with a maximum frequency of 3.4MHz for I2C and 10MHz for SPI communication. The selection can be made by positioning SMD jumpers labelled as COMM SEL to 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 LIS2DTW12 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. The Accel 19 also possesses two interrupts, IN1 and IN2, routed to the INT and PWM pins on the mikroBUS™ socket used to signal MCU that an event has been sensed entirely programmed by the user through the I2C/SPI interface.
The Accel 19 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.
