much better. madaling masilip yung code..

btw, mukhang logic lang talaga ang kelangan mo...

look at this one

Code:

void code_enter(void)
{
while(1)
{
scanned_key = scan_keypad();
decoded_key = decode_key(scanned_key);
code1[i] = decoded_key;

display_key(decoded_key);

i++;
}
}

you are using while(1), it will cause an infinite loop inside that function and walang control statement to break out of while(1)...

mrami n po ako tnry jan. lyk while(!PORTB),while(!decoded_key),while(decoded_key!=0x0a),while(0x0c). pro di k prn mkuha ang output. nng ngforce dn ako ng value for code1(0to5)--*1234*--, nkuha ko ung desired output w/c is RA0=0. tingin ko e ang prblem ng code ko e hndi nasasave ung value s code1. ano n po ggwin ko? sorry po.halos 1wik plng kc ako s high tech c.hehe thanks po s pgrply..

[cliff88]

hndi ko prn mkuha ung desired output.
phelp nmn po san ang mali dito.

void code_enter(void)
{

   while(PORTB!=12) (terminate when # is pressed. password*1234#)
   {
      
      scanned_key = scan_keypad();
      decoded_key = decode_key(scanned_key);
      display_key(decoded_key);

      if(PORTB!=0) (save the key pressed at code1(i) )
      {
       code1(i) = decoded_key;
       i++;
//       __delay_ms(150);
//       PORTB=0;
        return;
      }
            
//      code1[0] = 0x0a;
//      code1[1] = 0x01;
//      code1[2] = 0x02;
//      code1[3] = 0x03;
//      code1[4] = 0x04;
//      code1[5] = 0x0c;
//      PORTB=code1[5];
//      return;
   }
}
pg my forced value,nkukuha ko ang output. san po b mali ko.=(

kuya cliff88, pwede po b makita schem nito?.

[cliff88]

di ako marunong magpost ng image.hehe pero nakaindicate naman don ung mga connections e. indicator lng ung RA so kahit wag mo na lagyan ng LED kng s proteus m lng simulate. tapos lagyan m ng pull-up resistors ung mga columns.

[ion2557]

anong compiler po ginamit nyo dito?

[reaver26]

standalone setup po ito kuya? kasi naka indicate default pasword. hope makakuha ako ng IDEA dito para sa thesis namin...

[paranz]

anong compiler po ginamit nyo dito?

hitech c ang compiler...

If you download the latest MPLAB, merong included na hitech c student version..

On topic.
Looking at your code, I am wondering why you are testing for 0x0A (value of 9 from decode_key() function).
Does the user need to press 9 before and 9 after entering the password?
Or this is just copy/pasted from a PC program and trapping the ENTER key?

hindi po un 9. 0x0A is 10 or (asterisk--*) sa keypad. mali ung nalagay ko don s switch(val).hehe if your pasword is 1352, then you must enter *1352# para matrigger ung relay. # is always used as 'enter' key.
don din s program, ung line 218 & 219 wala dapat yan.ierase nyo yn. ewan bt nlagay ko yan jan.sa bago kong program wala na kasi yon.hehe
