Library Description
The library contains a function that checks and returns the state of the button - whether it is pressed or not. Using the PWM function, you can adjust the LED light button.
Key functions:
uint8_t buttony_getButtonState()
- Functions for Get Button stateExamples description
The application is composed of the three sections :
void applicationTask()
{
buttonState = buttony_getButtonState();
if ((buttonState == _BUTTONY_BUTTON_IS_PRESSED) && (_pressFlag == 0))
{
_pressFlag = 1;
}
if (_pressFlag == 0)
{
_dutyCycle += 250;
buttony_pwmSetDuty(_dutyCycle);
if (_dutyCycle > 10000 )
{
_dutyCycle = 0;
buttony_pwmSetDuty(_dutyCycle);
Delay_ms(2000);
}
Delay_ms( 50 );
}
else
{
if(buttonState == _BUTTONY_BUTTON_IS_PRESSED)
{
mikrobus_logWrite(" Button is pressed ", _LOG_LINE);
buttony_pwmSetDuty(10000);
Delay_ms( 2000 );
}
else
{
buttony_pwmSetDuty(0);
}
}
}

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
