Library Description

The library covers all the functions necessary for the use of Vibra sense Click board.
Vibra sense Click uses GPIO and PWM to communicate. This library contains drivers for
enabling or disabling PWM and for enabling, disabling or reseting the device itself and
a function for checking the interrupt pin.

Key functions:

• uint8_t vibrasense_checkInterrupt() -  Function is used to check for an interrupt that indicates that the device has detected vibrations.
• void vibrasense_enable()-  Function sets the RST pin.
• void vibrasense_reset() -   Function resets the device.

Examples Description

The application is composed of three sections:

• System Initialization - Initializes GPIO and LOG structures, sets RST pin as output and INT pin as input.
• Application Initialization - Enables GPIO and PWM, sets the frequency and duty cycle and makes an initial log.
• Application Task - (code snippet) This is a example which demonstrates the use of Vibra sense Click board. It detects vibrations and enables PWM and writes log according to them.

void applicationTask()
{
    if( vibrasense_checkInterrupt() )
    {
        mikrobus_logWrite( "       TILT!!!     ", _LOG_LINE );
        mikrobus_logWrite( "-------------------", _LOG_LINE );
        vibrasense_pwmStart();
        Delay_ms( 100 );
        vibrasense_pwmStop();
        Delay_ms( 200 );
    }
}  

Other mikroE Libraries used in the example:

• PWM
• 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
