Software Support

We provide a library for the HallCurrent4 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

This library provides basic functionality for reading the current value and controlling the click board.

Key functions :

• float hallcurrent4_getCurrent() - Reads current in mA
• uint16_t hallcurrent4_readData() - Reads current 12bit data

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializations driver init
• Application Task - (code snippet) - Reads Current value in mA and logs this data to USBUART every 1 sec.

void applicationTask()
{
    char demoText[ 50 ];
    float Current;

    Current = hallcurrent4_getCurrent();

    mikrobus_logWrite(" Current value: ", _LOG_TEXT);
    FloatToStr(Current, demoText);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mA", _LOG_LINE);
    
    mikrobus_logWrite(" ------------------------- ", _LOG_LINE );
    Delay_ms( 1000 );
}

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

Other mikroE Libraries used in the example:

• I2C
• 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.
