La carte Click Board™ Angle 6 est une carte complémentaire compacte qui détecte la position angulaire absolue d'un aimant permanent, généralement un cylindre diamétralement magnétisé sur un arbre rotatif. Cette carte est équipée du MAQ470GQE, un capteur d'angle sans contact 12 bits avec sortie PWM de Monolithic Power Systems. Il prend en charge de nombreuses intensités de champ magnétique et configurations spatiales, avec des configurations prises en charge en bout d'arbre et hors axe (montage sur arbre latéral). L'acquisition et le traitement rapides des données permettent une mesure précise de l'angle à des vitesses de 0 à 60 000 tr/min, ainsi qu'une détection de l'intensité du champ magnétique avec des seuils programmables. Cette carte Click™ offre une méthode hautement fiable et sans contact pour mesurer les angles, la position et la vitesse de diverses applications.
La carte Click Board™ Angle 6 prend en charge la bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Angle 6 Click Board™ Work?
The Angle 6 Click Board™ is based on the MAQ470GQE, 12-bit PWM output angle sensor that detects the absolute angular position of a permanent magnet, typically a diametrically magnetised cylinder on a rotating shaft from Monolithic Power Systems. It allows users to read angle position information and detect the speed or direction of magnet rotation. Fast data acquisition and processing provide accurate angle measurement at rates from 0 to 60,000rpm. It supports many magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations.
The MAQ470GQE features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor to create functions such as sensing axial movements or diagnostics. It can operate over a wide magnetic field range from 30mT to 150mT (60mT typical) with 5mT accuracy. Eight magnetic field thresholds are programmable in approximate 15mT steps allowing detection of changes in the distance between the magnet and the sensor. On-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position and magnetic field detection thresholds.
The magnetic field is detected with integrated Hall devices located in the sensors' centre. The angle is measured using the Spinaxis™ method, based on phase detection generating a sinusoidal signal with a phase representing the angle of the magnetic field. The angle is then obtained by a time-to-digital converter, representing output from the front-end to the digital conditioning block, which measures the time between the zero-crossing of the sinusoidal signal and the edge of a constant waveform. This output delivers a digital number proportional to the angle of the magnetic field at the rate of 1MHz in a straightforward and open-loop manner.
The Angle 6 Click Board™ communicates with MCU using the standard SPI serial interface for angle reading and register programming, which supports SPI Mode 0 and 3 and operates at clock rates up to 25 MHz. It also has the magnetic flags used to indicate when the sensor position's magnetic field is out of range, defined by the lower and upper magnetic field thresholds, routed on the RST and INT pins of the mikroBUS™ socket labelled as MGH and MGL.
The Angle 6 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.

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART Click Board™, 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. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The Angle 6 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.
