Library Description

Library provides functions for reading ADC value, and function for reading converted ADC data to mA

Key functions:

• uint16_t amrcurrent_read_value ( void ) - .Reads ADC current data
• float amrcurrent_get_current ( void ) - .Reads current data in mA

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializations driver init
• Application Task - Reading ADC data and converted current mA data from device and logs it to device

void application_task ( )
{
    read_adc_val = amrcurrent_read_value(  );
    WordToStr( read_adc_val, demo_txt );
    mikrobus_logWrite( " - ADC value: ", _LOG_TEXT );
    mikrobus_logWrite( demo_txt, _LOG_LINE );

    Delay_ms( 100 );

    read_curr_val = amrcurrent_get_current(  );
    FloatToStr( read_curr_val, demo_txt );
    mikrobus_logWrite( " - Current value: ", _LOG_TEXT );
    mikrobus_logWrite( demo_txt, _LOG_TEXT );
    mikrobus_logWrite( "mA", _LOG_LINE );
    
    Delay_ms( 100 );
    
    mikrobus_logWrite( "-------------------------", _LOG_LINE );
    
    Delay_ms( 5000 );
}

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.
