Library Description

The library contains basic functions for using VCT monitor click.

Key functions:

• float vctmonitor_read_voltage_differential ( void ) - Differential voltage function
• float vctmonitor_read_current ( void ) - Current function
• float vctmonitor_read_temperature ( void ) - Temperature function

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializes driver init
• Application Task - Reads temperature, current value, and differential voltage every 4 seconds.
• note - We used the next sets for the test: - Power supply - 4V - Current (Load) - 0A to 3A - The temperature reads from the external MMBT3904 sensor

void application_task ( )
{
    float temperature;
    float voltage;
    float current;
    
    current = vctmonitor_read_current( );
    FloatToStr( current,demo_text );
    mikrobus_logWrite( "Current: ",_LOG_TEXT );
    mikrobus_logWrite( demo_text,_LOG_TEXT );
    mikrobus_logWrite( "mA",_LOG_LINE );

    voltage = vctmonitor_read_voltage_differential( );
    FloatToStr( voltage,demo_text );
    mikrobus_logWrite( "Voltage: ",_LOG_TEXT );
    mikrobus_logWrite( demo_text,_LOG_TEXT );
    mikrobus_logWrite( "mV",_LOG_LINE );

    temperature = vctmonitor_read_temperature();
    FloatToStr( temperature, demo_text );
    mikrobus_logWrite( "Temperature: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT);
    mikrobus_logWrite( "C",_LOG_LINE );

    mikrobus_logWrite("_________________",_LOG_LINE);
    Delay_ms( 4000 );
}

Other mikroE Libraries used in the example:

• I2C Library
• Conversions Library
• UART Library

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.
