Could u plz help me in code of voting machine whr the code has to be done with some modifications.
the control according to the code is taking many votes at a time but in voting the control shud go back to the entry state where it takes only one input
Code is :
#include<stdint.h>
#include<stdio.h>
#include "scankey.h"
#include "NUC1xx.h"
#include "DriverDrvSYS.h"
#include "NUC1xx-LB_002LCD_Driver.h"

int8_t number8;
char t1[50]="a";
char t2[50]=": ";
char TEXT0[50]="Press 8 to vote ";
char TEXT1[50]="WELCOME! VOTE P1 P2 P3 P4";
