Library Description

The library covers all functions to control MIC23099 click board.
It offers: enable, disable, reset and check "power good" pin functions to the user. 

Key functions:

• mic23099_enable() - Function enables the device by seting EN pin.
• mic23099_disable() - Function disables the device by clearing EN pin.
• mic23099_checkPowerGood() - Function checks the state of Power Good output pin.

Examples description

The application is composed of three sections:

• System Initialization - Initializes GPIO and LOG structures, sets CS pin as output and INT pin as input.
• Application Initialization -  Initialization driver enables GPIO, enables the device and also starts write log.
• Application Task - (code snippet) This example demonstrates the use of MIC23099 Click board by checking the state of power goof pin and sends note via usart terminal if the state is low.

void applicationTask() 
{
    uint8_t newStat = 0;
    uint8_t oldStat = 1;
    
    newStat = mic23099_checkPowerGood();
    if ( newStat == 1 && oldStat == 0 )
    {
        oldStat = 1;
    }

    if ( newStat == 0 && oldStat == 1 )
    {
        mikrobus_logWrite( "Change  battery  and  reset", _LOG_LINE );
        mikrobus_logWrite( "- - - - - - - - - - - - - -", _LOG_LINE );
        oldStat = 0;
    }
}        

Other mikroE Libraries used in the example:

• 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
