Le Tableau à cliquer 3D Hall 8™ est une carte complémentaire compacte contenant un capteur magnétique 3D ultra-petit pour les applications industrielles et grand public. Cette carte comprend le TLI493D-W2BW, un capteur Hall 3D à faible consommation d'énergie d'Infineon. Ce capteur magnétique combine des mesures de champ magnétique de haute précision avec une consommation d'énergie exceptionnellement faible (minimum 7 nA). Il dispose d'une interface I2C, ce qui lui permet d'être facilement configuré par MCU avec les données de mesure fournies au format numérique. Il offre également la fonctionnalité de réveil d'un système en veille. Cette Click Board™ convient à une large gamme de détection magnétique, y compris la détection de position robotique, la mesure d'angle à l'extrémité de l'arbre et les configurations hors arbre, et bien d'autres encore.
Le Hall 8 3D Cliquez est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The 3D Hall 8 Click Board™ Work?
The 3D Hall 8 Click Board™ as its foundation uses the TLI493D-W2BW, a low-power 3D Hall sensor with an I2C interface and Wake-Up feature from Infineon. It consists of three central functional units; containing a power mode control system, a low-power oscillator, basic biasing, Undervoltage detection, and a fast oscillator. Besides, it has also implemented the sensing unit, which contains the HALL biasing, HALL probes with multiplexers and successive tracking ADC, and a temperature sensor. This sensor offers several use cases, including innovative human-machine interfaces in the form of industrial and consumer joysticks and precise position control in robotics.
The power mode control provides the power distribution, which manages the Start-Up behaviour in the TLI493D-W2BW, a power-on reset function, and a specialized low-power oscillator, the clock source. The sensing unit measures the magnetic field in the X, Y, and Z directions. Each X-, Y- and Z-Hall probe is connected sequentially to a multiplexer, connected to an analogue to digital converter. Optional, the temperature measurement feature, activated in the default state, can be determined after the three Hall channels.
3D Hall 8 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode operation with a clock frequency up to 1MHz. For each of the three magnetic channels (X/Y/Z), the Wake-Up function has an upper and lower comparison threshold. Each component of the applied field is compared to the lower and upper thresholds. If one of the results is above or below these thresholds, an interrupt is generated called a Wake-Up function. The Wake-Up mode allows the sensor to continue making magnetic field measurements while the MCU is in the power-down state, which means the microcontroller will only consume power and access the sensor if relevant measurement data is available.
An interrupt pin signals a finished measurement cycle but also can be used for I2C clock stretching. In this case, the INT pin must be connected to the SCL pin, which can be done by populating the jumper labelled JP1.
The 3D Hall 8 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with 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.

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The 3D Hall 8 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
