Library Description

Library contains functions for reading voltage.

Key functions:

• void rng_write_data ( uint8_t reg_addr, uint16_t reg_data ); - Generic funcion for writing.
• void rng_set_config ( uint16_t conf_data ); - Function used for set configuration.
• float rng_get_voltage ( ); - Function used for get voltage.

Examples description

The application is composed of three sections :

• System Initialization - Initializes i2c module
• Application Initialization - Initializes driver, set configuration and voltage reference.
• Application Task - (code snippet) - Measures voltage every seconds.

void application_task ( )
{
    char demoText[ 50 ];
    float voltage;

    voltage = rng_get_voltage();

    mikrobus_logWrite( " ~~~> Voltage value: ", _LOG_TEXT );
    FloatToStr( voltage , demoText );
    mikrobus_logWrite( demoText, _LOG_TEXT );
    mikrobus_logWrite( " mV  ", _LOG_LINE );

    mikrobus_logWrite("_______________________________", _LOG_LINE );
    mikrobus_logWrite(" ", _LOG_LINE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• Conversions
• I2C
• UART

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.
