/*************************************************************************** ** ** ** This is program Fire Alarm ** ** Smart Home ** ** By Group 2 ** ** Microcontroller and Microprocessor project ** ** ** ** ** **************************************************************************//*Program ini menggunakan Nuvoton NUC 140VE3CN sebagai mikrokontroller. Dengan menggunakan sensor IR Flame sebagai pendeteksi api yang disambungkan pin GPA6, program akan memberi peringatan jika terdapat kebakaran dan akan menghidupkan buzzer, LED dan peringatan melalui LCD, serta akan member sinyal low ke pin GPC 12 yang disambungkan ke lampu sebagai indikator pelistrikan yang mati akibat terdeteksi kebakaran.*/#include //standard input output library#include "NUC1xx.h"#include "LCD_Driver.h" //LCD header#include "DrvADC.h"//ADC header#include "DrvGPIO.h" //LED library#include "DrvSYS.h"//LED library#include "ScanKey.h" //Button Matrix header#include "scanpad.h" //Button Matrix headerint reset=0 ;//flag resetint result ;//flag detectedint key ;//variabel key pertamaint pad ;//variabel key kedua/*------------------------------------------------------------------------*//* Subrutin InitADC *//*------------------------------------------------------------------------*/void InitADC(void){/* Step 1.
