Library Description

The library covers the necessary function that enables the usage of the RTC 11 Click board. User can enable or disable the device.

Key functions:

• void boost3_dev_enable ( uint8_t state ); - Function is used to enable or disable the device.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, and set CS pin as output.
• Application Initialization - Start to write log and gives instructions to the user.
• Application Task - Demonstrates use of Boost 3 click board by by reading user's command input from USART terminal and turning the device on or off accordingly. User can use the on-board potentiometer to adjust 'Vout' voltage.

void application_task ( )
{  
    char cmd;
    if ( UART_Rdy_Ptr() )
    {
        cmd = UART_Rd_Ptr( );
        cmd -= 48;
        boost3_dev_enable( cmd );
        if( cmd == BOOST3_ENABLE )
        {
            mikrobus_logWrite( "The device is turned on!", _LOG_LINE );
            mikrobus_logWrite( "Use on-board potentiometer", _LOG_LINE );
            mikrobus_logWrite( " to adjust 'Vout' voltage", _LOG_LINE );
        }
        else
        {
            mikrobus_logWrite( "The device is turned off!", _LOG_LINE );
        }
    }
}

Other mikroE Libraries used in the example:

• GPIO
• 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.
