Detailed Description

LDC Click example.

Description

This example showcases the ability of the device to detect metal objects. It configures a device for reading data from channel 0, checks if ID's are OK and reads data when interrupting is asserted and logs result.

The demo application is composed of two sections :

Application Init

Initialization of communication modules (I2C, UART) and additional pins. Then configures the device for reading data from channel 0, and checks if device ID's are correctly read, and read the currently set divider.

Application Task

Checks if interrupt pin is asserted, if so reads data from channel 0. Calculates and returns the frequency of the sensor. If the frequency is greater than 0, then it calculates the inductance of the sensor. It will log error and error values if it occurred.

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.
