Library Description

The library contains basic communication with the module and allows the user to read and write data to the module. The user can read the current data of current, voltage and power measured by the sensor.

Key functions:

• float vcpmonitor_get_voltage ( void ) - Reads voltage data in mV
• float vcpmonitor_get_current ( void ) - Reads current data in mA
• float vcpmonitor_get_power ( void ) - Reads power data in mW

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module and INT pin on INPUT
• Application Initialization - Initializes driver init, check device ID and manufacture ID, start default configuration.
• Application Task - Reads Current, Voltage and Power data. This data logs to USB UART every 1500ms.

void application_task ( )
{
    float current_data;
    float voltage_data;
    float power_data;
    
    current_data = vcpmonitor_get_current(  );
    IntToStr( current_data, demo_text );
    mikrobus_logWrite( ">> Current data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mA", _LOG_LINE );
     
    voltage_data = vcpmonitor_get_voltage(  );
    IntToStr( voltage_data, demo_text );
    mikrobus_logWrite( ">> Voltage data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mV", _LOG_LINE );
    
    power_data = vcpmonitor_get_power(  );
    IntToStr( power_data, demo_text );
    mikrobus_logWrite( ">> Power data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mW", _LOG_LINE );
    
    mikrobus_logWrite( " ------------------------------- ", _LOG_LINE );
    Delay_ms( 1500 );
}

• Conversions 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.
