Click library

Software Support

We provide a library for the Ldc1101 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Ldc1101 Click driver.

Standard key functions :

Example key functions :

Examples Description

Example demonstrates measurement of inductance change depending on the linear motion of the metal object. Induction of the linear metal position depends on the type of metal and the configuration.

The demo application is composed of two sections :

Application Init

Initializes I2C module and sets CS pin as OUTPUT and PWM and INT pin sa INPUT. Driver intialization, standard configurations and start measurement.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
LDC1101_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ldc1101_init( &ldc1101, &cfg );
log_printf( &logger, " LDC1101 Click\r\n" );
log_printf( &logger, "------------------------\r\n" );
ldc1101_default_cfg ( &ldc1101 );
Delay_ms( 100 );
}

Application Task

Reads RP data and logs data to USBUART every 1 sec.

void application_task ( void )
{
uint16_t rp_data;
rp_data = ldc1101_get_rp_data( &ldc1101 );
log_printf( &logger, " Inductive Linear Position : %u\r\n", rp_data );
Delay_ms( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
