Library Description

The library covers all the necessary functions to control Current 3 Click board. A library performs the communication with the device via I2C interface.

Key functions:

• float current3_get_temperature ( uint8_t temp_sel ) - Get temperature function.
• float current3_get_source_voltage ( void ) - Get source voltage function.
• float current3_get_current ( void ) - Get current measurement function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C and start to write log.
• Application Initialization - Initialization driver enables - I2C, check communication and set sense sampling configuration, also write log.
• Application Task - (code snippet) This is an example which demonstrates the use of Current 3 Click board. Current 3 Click board can be used to measure current ranging up to 8000mA, and display temperature, voltage and current data. All data logs write on USB uart changes for every 2 sec.

void application_task ( )
{
    temperature = current3_get_temperature( CURRENT3_TEMP_INTERNAL_DIODE );
    FloatToStr( temperature, log_text );
    Ltrim( log_text );
    mikrobus_logWrite( " Temperature = ", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( " C", _LOG_LINE );

    voltage = current3_get_source_voltage( );
    FloatToStr( voltage, log_text );
    Ltrim( log_text );
    mikrobus_logWrite( " Voltage     = ", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( " V", _LOG_LINE );

    current = current3_get_current( );
    FloatToStr( current, log_text );
    mikrobus_logWrite( " Current     = ", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( " mA", _LOG_LINE );
    mikrobus_logWrite( "---------------------------", _LOG_LINE );
    Delay_ms( 2000 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
