Library Description
The library covers all the necessary functions to control Button ALARM Click board. The library contains a function that checks and returns the state of the alarm button - whether it is pressed or not. Using the PWM function, you can adjust the LED light of the alarm button.
Key functions:
uint8_t buttonalarm_getButtonState()
- Gets state of the alarm button function.Examples description
The application is composed of the three sections :
void applicationTask() { buttonState = buttonalarm_getButtonState(); cnt = 0; while ( ( cnt < 200 ) && ( buttonState == _BUTTONALARM_BUTTON_STATE_OFF ) ) { buttonState = buttonalarm_getButtonState(); buttonalarm_pwmSetDuty( _BUTTONALARM_DUTY_CYCLE_ON ); cnt++; Delay_ms( 1 ); } cnt = 0; while ( ( cnt < 200 ) && ( buttonState == _BUTTONALARM_BUTTON_STATE_OFF ) ) { buttonState = buttonalarm_getButtonState(); buttonalarm_pwmSetDuty( _BUTTONALARM_DUTY_CYCLE_OFF ); cnt++; Delay_ms( 1 ); } if( buttonState ) { mikrobus_logWrite(" Button is pressed ", _LOG_LINE); while ( dutyCycle < _BUTTONALARM_DUTY_CYCLE_ON ) { dutyCycle += 200; buttonalarm_pwmSetDuty( dutyCycle ); if ( dutyCycle > _BUTTONALARM_DUTY_CYCLE_ON ) { dutyCycle = _BUTTONALARM_DUTY_CYCLE_OFF; buttonalarm_pwmSetDuty( dutyCycle ); Delay_ms( 100 ); } Delay_ms( 50 ); } dutyCycle = _BUTTONALARM_DUTY_CYCLE_OFF; mikrobus_logWrite( "---------------------", _LOG_LINE ); } }

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.
