Software Support

We provide a library for the LDC1101 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines the SPI bus driver and drivers that offer a choice for writing data in address and reading data from address. The library includes function for read RP data and L data. The user also has the function for initializes chip, funstion for go to RP mode or L mode, Function for set porew mode and function for read interrupt state.

Key functions :

• uint8_t ldc1101_init() - Functions for initialization chip
• void ldc1101_setPowerMode(uint8_t mode) - Functions for settings power mode
• void ldc1101_goTo_RPmode() - Functions for go to RP mode
• uint16_t ldc1101_getRPData() - Functions for reads RP data

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module and sets CS pin as OUTPUT and PWM and INT pin sa INPUT

• Application Initialization - Driver intialization, standard configurations and start measurement

• Application Task - (code snippet) - Reads RP data and logs data to USBUART every 100 ms.

• note: 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.

void applicationTask()
{
    RP_Data = ldc1101_getRPData();
    IntToStr(RP_Data, demoText);
    mikrobus_logWrite(" Inductive Linear Position :", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);
    Delay_100ms();
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• SPI
• UART

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.
