HOW DOES IT WORK?
Angle 9 Click is based on the AAS33001, a precision angle sensor with incremental and motor commutation outputs and on-chip linearization from Allegro Microsystems. It is a rotary position circular vertical Hall-sensor-based device (CVH), incorporating one electrically independent Hall sensor die, thus providing solid-state consistency and reliability. The Hall sensor measures the magnetic field vector through a 360° in the x-y plane parallel to the face of the angle sensor. The Hall sensor also computes an angle measurement based on the actual physical reading and internal parameters that the user has set.
The Angle 9 Click can monitor the angular position of a rotating magnet at speeds ranging from 0 up to 15,000 RPM with a refresh rate of 1μs. For testing purposes, this Click board™ can be used with a rotary magnetic holder, which is sold separately. It is a unique addition that can be used alongside a precision angle sensor allowing fast prototyping and quick measurement during development. This magnetic holder is an adjustable shaft with a 6mm diameter magnet that can be positioned right above the angle sensor.
The Ange 9 Click also has a header that allows you to use it with additional devices over the ABI and UVW interfaces. Both interfaces use all three pins (A/U, B/V, I/W), so you can't use both at the same time. The Incremental Output Interface (ABI) is available in the form of quadrature A/B and Index outputs to emulate an optical or mechanical encoder. The brushless DC motor output is available over the U, V, and W signals for stator commutation of brushless DC (BLDC). The device is mode-selectable for 1 to 16 pole pairs. PWM output is always resolved to a 12-bit angle resolution. The external power supply can be selected over the VCC SEL jumper with 5V from the mikroBUS™ socket chosen by default. The external power supply can range from 3.7 to 18V and be connected over the header terminal.
Angle 9 Click uses a full-duplex standard 4-Wire SPI serial interface to communicate with the host MCU, using SPI mode 3 and supporting frequencies up to 10MHz. The readout is possible with a 12-bit resolution with error flags or a 15-bit resolution without error flags. The angle sensor can be reset over the RST pin. The PWM interface over the PWM pin provides the initial position for ABI/UVW interfaces.
This Click board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. This Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
