Library Description

The library covers all the necessary functions to control Charger 13 Click board. The library contains a function which enables or disable charging and check battery charging states.

Key functions:

• void charger13_enable() - Enable the charging function.
• void charger13_disable() - Disable the charging function.
• uint8_t charger13_check() - Check battery charging function

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, sets INT pin as input and PWM pin as output and start to write log.
• Application Initialization - Initialization driver enable's - GPIO, also write log.
• Application Task - (code snippet) This is an example which demonstrates the use of Charger 13 click board. This example shows the automatic control of the Charger 13 click, waits for valid user input and executes functions based on a set of valid commands and check the battery charge status. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for approximately every 1 sec when the data value changes.
• Commands : 'E' - Enable charging; 'D' - Disable charging;

void applicationTask()
{
    char receivedData;

    if ( UART_Rdy_Ptr() )
    {
        receivedData = UART_Rd_Ptr();

        switch ( receivedData )
        {
            case 'E' :
            {
                if ( enableFlag == 0 )
                {
                    enableFlag = 1;
                    charger13_enable();
                    mikrobus_logWrite( "Charging Status : Enabled", _LOG_LINE );
                    mikrobus_logWrite( "-------------------------", _LOG_LINE );
                }
                break;
            }
            case 'D' :
            {
                if ( enableFlag == 1 )
                {
                    enableFlag = 0;
                    charger13_disable();
                    mikrobus_logWrite( "Charging Status : Disable", _LOG_LINE );
                    mikrobus_logWrite( "-------------------------", _LOG_LINE );
                }
                break;
            }
        }
    }

    if ( charger13_check() != chargerFlag )
    {
        chargerFlag = charger13_check();
        
        if ( chargerFlag == 0 )
        {
            mikrobus_logWrite( "   Battery is charging   ", _LOG_LINE );
            mikrobus_logWrite( "-------------------------", _LOG_LINE );
        }
        else
        {
            mikrobus_logWrite( " Battery does not charge ", _LOG_LINE );
            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.
