Library Description

The library covers all the necessary functions to control Tamper 2 Click board.
Tamper 2 click communicates with the target board through the AN and INT line. 
This library detecting the state of switch on Tamper 2 click is changes to normally open or closed.

Key functions:

• uint8_t tamper2_switchON() - Switch ON detect function.
• uint8_t tamper2_switchOFF() - Switch OFF detect function.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes GPIO and LOG structures, sets AN and INT pins as input.
• Application Initialization - Initialization driver enables GPIO and also starts write log.
• Application Task - (code snippet) This is a example which demonstrates the use of Tamper 2 Click board. Detects whether the state of switch on Tamper 2 click is changes to normally open or closed.
  Results are being sent to the Usart Terminal where you can track their changes.
  All data logs on usb uart changes when the change switch status is detected.

void applicationTask()
{      
    switchState = tamper2_switchON();

    if ( switchState == 1 && switchStateOld == 0 )
    {
        mikrobus_logWrite( " Closed ", _LOG_LINE );
        mikrobus_logWrite( "- - - - - - - - -", _LOG_LINE );
        switchStateOld = 1;
    }

    if ( switchState == 0 && switchStateOld == 1 )
    { 
        mikrobus_logWrite( " Open ", _LOG_LINE );
        mikrobus_logWrite( "- - - - - - - - -", _LOG_LINE );
        switchStateOld = 0;
    }
}

Other mikroE Libraries used in the example:

• GPIO
• UART

Additional notes and information

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.
