LDC Click is a compact add-on board that measures inductance change which a conductive target causes when it moves into the inductor's AC magnetic field.
We provide a library for the LDC Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for LDC Click driver.
ldc_cfg_setup
Config Object Initialization function. ldc_init
Initialization function. ldc_default_cfg
Click Default Configuration function. ldc_get_interrupt
Get interrupt pin status. ldc_get_frequency
Get frequency value calculated for specific channel. ldc_calculate_inductance
Calculate inductance relative to frequency. This example showcases abillity of the device to detect
metal objects. It configures device for reading data from channel 0, checks if ID's are OK and reads data when interrupt is asserted and logs result.
The demo application is composed of two sections :
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.
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.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
