Detailed Description

Index Counter Click example.

Description

This application enables usage of Index counter click board which can be used to measure rotational speed.

The demo application is composed of two sections :

Application Init

Initilaziation of GPIO and write log.

Application Task

This is an example which demonstrates the use of the Index Counter click board. This example shows the direction of movement, Rotations Per Minute ( RPM or speed ) of the three pairs of rotating poles positioned in the sensor operating range. Results are being sent to the Usart Terminal where you can track their changes.

note: Additional Functions :

• void log_display ( float rpm_val ) - The function displays all results and a float value with a comma with two decimal places.

Note

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.
