Library Description

The library covers all the necessary functions to control the Comparator click board. Comparator click communicates with the device via GPIO driver. This library contains drivers for check state of the OUT1 and OUT2 pin function.

Key functions:

• uint8_t comparator_checkOutputOne() - Check state of the OUT1 pin function.
• uint8_t comparator_checkOutputTwo() - Check state of the OUT2 pin function.

Examples description

The application is composed of three sections:

• System Initialization - Initializes GPIO and LOG structures, sets AN and INT pins as input and start to write log.
• Application Initialization -  Initialization driver enables - GPIO also, write log.
• Application Task - (code snippet) This is an example which demonstrates the use of Comparator click board. Comparator clicks checks state of the OUT1 and OUT2 pins. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 1 sec.

void applicationTask() 
{
    outStateOne = comparator_checkOutputOne();
    outStateTwo = comparator_checkOutputTwo();
    
    mikrobus_logWrite( " Output One : ", _LOG_TEXT );
    
    if ( outStateOne )
        mikrobus_logWrite( "High", _LOG_LINE );
    else
        mikrobus_logWrite( "Low", _LOG_LINE );

    mikrobus_logWrite( " Output Two : ", _LOG_TEXT );

    if ( outStateTwo )
        mikrobus_logWrite( "High", _LOG_LINE );
    else
        mikrobus_logWrite( "Low", _LOG_LINE );
    
    mikrobus_logWrite( "-------------------", _LOG_LINE );
    Delay_1sec();
}       

Other mikroE Libraries used in the example:

• GPIO
• UART​
• Conversion

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
