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 the 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 );
}

Other mikroE Libraries used in the example:

• I2C
• UART

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
