Overview
La carte Click Board™ Angle 7 est une carte complémentaire compacte qui détecte la position angulaire absolue d'un aimant permanent. Cette carte est équipée de l'AS5600, un capteur de position magnétique rotatif programmable à effet Hall avec une sortie analogique ou PWM 12 bits haute résolution d'AMS AG. Basé sur la technologie Hall planaire, ce capteur mesure la composante orthogonale de la densité de flux (Bz) d'un aimant externe tout en rejetant les champs magnétiques parasites. La plage par défaut de la sortie est de 18 à 360 degrés, où la résolution complète de l'appareil peut être appliquée à une plage plus petite en programmant un angle nul (position de départ) et un angle maximal (position d'arrêt) via l'interface I2C utilisée pour la configuration et la programmation utilisateur des paramètres non volatils. Cette carte Click™ convient aux potentiomètres sans contact, aux boutons sans contact, aux servos RC et à d'autres solutions de mesure de position angulaire.
La carte Click Board™ Angle 7 est prise en charge par une 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™.
Remarque : le Click Board n'inclut pas l'aimant, le support ni le bouton de commande. Ceci est présenté à titre d'exemple d'application.

How Does The Angle 7 Click Board™ Work?
The Angle 7 Click Board™ as its foundation uses the AS5600, an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog or PWM output from AMS AG. The AS5600 is a Hall-based rotary magnetic position sensor using planar sensors that convert the magnetic field component perpendicular to the surface of the chip into a voltage. It measures the absolute angle of a diametric-magnetized on-axis magnet while at the same time rejecting stray magnetic fields. By default, the output represents a range from 18 to 360 degrees. It is also possible to define a smaller range to the output by programming a zero angle (start position) and a maximum angle (stop position).
The signals coming from internal Hall sensors are first amplified and filtered before their conversion by the ADC and then processed by the hardwired CORDIC block to compute the angle and magnitude of the magnetic field vector. The intensity of the magnetic field is used by the automatic gain control (AGC) to adjust the amplification level to compensate for temperature and magnetic field variations. After that, the output stage uses the angle value provided by the CORDIC algorithm. The user can choose between an analog output representing the angle as a ratiometric linear absolute value and a digital PWM-encoded output representing the angle as the pulse width. The selection can be made by positioning the SMD jumper labelled as OUT SEL in an appropriate position marked as AN or INT.
The Angle 7 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz, fully adjustable through software registers. Also, the DIR SEL jumper allows users to select the polarity of the output relative to rotation direction by positioning the SMD jumper in an appropriate position marked as CW or CCW allowing clockwise or counterclockwise rotation. A unique addition to this board is a position for a rotary magnet holder designed to be used alongside a magnetic rotary position sensor allowing fast prototyping and quick measurements during development.
The Angle 7 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. Both mikroBUS™ power rails have protection in the form of diode MAX40200, controllable through an EN pin on the mikroBUS™ socket to prevent any unwanted back voltage. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
NOTE: In the case of using a logic level of 5V, it is necessary first to remove the resistor R6 and only then switch the VCC jumper to the 5V position.
