Library Description

This library allows user to perform a control of the Analog Mux Click board. Also user can check the indication status from the charger to get charging state. Fault condition also can be checked. For more details check documentation.

Key functions:

• float analogmux_get_voltage ( float adc_value ); - Function used for get voltage
• void analogmux_set_channel ( uint8_t set_channel ); - Function used for set channel
• void analogmux_set_adc_vref ( uint16_t vref_mV ); - Function used for set vref in millivolts

Examples description

The application is composed of three sections :

• System Initialization - Initializes ADC module
• Application Initialization - Initializes driver and adc, and set vref and channel.
• Application Task - (code snippet) - Measures adc_value and voltage every 2 sec on set channel.

void application_task ( )
{
    uint8_t cnt = 0;
    float voltage = 0;
    float average_f = 0.0;
    volatile uint32_t average_value = 0;
    char demo_text[ 50 ];
    
    for( cnt = 0; cnt < 10; cnt++ )
    {
        average_value += analogmux_adc_read( );
    }
              
    average_f = average_value / 10.0;
    
    FloatToStr( average_f, demo_text );
    mikrobus_logWrite( "        ADC value: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    
    voltage = analogmux_get_voltage( average_f );
    FloatToStr( voltage, demo_text );
    mikrobus_logWrite( "        Voltage: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    Delay_ms( 2000 );
    
    mikrobus_logWrite( " <<< ------------------------ >>> ", _LOG_LINE );
}

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.
