Detailed Description

Speed Sense Click Example.

Description

This library contains the API for the Speed Sense Click driver for the speed and direction signal state detection for every magnetic pole pair.

The demo application is composed of two sections :

Application Init

Initialization of GPIO and log UART.

Application Task

This example demonstrates the use of the Speed Sense Click board. The demo application displays the direction of movement and rotation speed (rotations per minute) of the ring magnet with three pairs of rotating poles positioned in the sensor operating range.

If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
