SOLDERING AND PROGRAM THE LCD

WEEK 8

Throughout this entire week, I tried to complete the solder and the program which is upgrade with the LCD. the completed program will determine the effectiveness and success of this project. After making several references and corrections, the program which caters to what i wanted was achieved. i then tried to ensure that the program together with the hardware is working perfectly. I use PIC compiler for the software of assembly language that I used in this project. Then used software Winpic800 for download program to PIC microcontroller. The PIC programmer was connected to the computer via serial port/USB Port. Then, the PIC is placed into the programmer socket. At the desktop, the „Winpic800‟ folder is copied and the file of
 Winpic800.exe‟ is selected. My coding is below:

solder the LCD

#use delay(clock=20000000)

#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,PARITY=N)

#fuses hs,noprotect,nowdt,nolvp

#define use_portb_lcd TRUE  // lcd di sambung pada port B

   set_tris_c(0b10000011);

    output_low(PIN_d0);

    output_low(PIN_d1);

   output_low(PIN_C2);

   delay_ms(1000);

   output_high(PIN_C2);

   buffer[0]=0;

   buffer[1]=0;

   buffer[2]=0;

   do

   {

            lcd_gotoxy(1,1);

            lcd_putc("     PLEASE     ");

            lcd_gotoxy(1,2);

            lcd_putc("   TOUCH CARD   ");

       detect_card();

       printf("Hex: %X%X%X  ",buffer[2],buffer[1],buffer[0]);

       if(buffer[2]==0x7E&& buffer[1]==0x0D && buffer[0]==0x76)

       {

            lcd_gotoxy(1,1);

            lcd_putc("FARAH NAZIHAH   ");

            lcd_gotoxy(1,2);

            lcd_putc("51211112350     ");

             output_high(pin_d0);

            lcd_putc("     PLEASE     ");

            lcd_gotoxy(1,2);

            lcd_putc("   TOUCH CARD   ");

       }

       else

       {

            lcd_gotoxy(1,1);

            lcd_putc("      SORRY     ");

            lcd_gotoxy(1,2);

            lcd_putc("  INVALID CARD  ");

            output_high(pin_d1);

            delay_ms(3000);

            output_low(pin_d1);

            lcd_gotoxy(1,1);

            lcd_putc("     PLEASE     ");

            lcd_gotoxy(1,2);

            lcd_putc("   TOUCH CARD   ");

       }

   }while(1);

}

void detect_card()

{

      for(i=0; i<26;i++)

      {       while(input(PIN_C0)==1 && input(PIN_C1)==1);

               if(input(PIN_C0)==0 )

               {       if(i!=0 && i != 25)

                        {    shift_left(buffer,3,0); }

               }

               if(input(PIN_C1)==0)

               {        if(i!=0 && i != 25)

                        {shift_left(buffer,3,1); }

               }

               delay_us(500);

      }

}

*after the output relay through the solenoid with active high then LCD will display my ID n my name

DISCUSS WITH SUPERVISOR STRUCTURAL OF PROJECT

WEEK 7

I show to sir Muhyi project that i have already done. Then he advised me to upgrade the project with add the limit switch and LCD to make this project more attracted. He also want me change the prototype from the plastic to wood. Then i change the prototype from the below to wood. Because it look more common. 

EDIT THE SOFTWARE

WEEK 6

As for the develoment of this project, this project will depends on program that I compile. By using PIC Compiler software, I construct the program and there were a lot of mistakes also more things to learn to do the program. To complete and perfecting the program, I do lot a lot of research and ask my friend to teach me. Finally i have done the software.

#include <16f877A.h>

#use delay(clock=20000000)

#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,PARITY=N)

#fuses hs,noprotect,nowdt,nolvp

#byte PORTD=6

#byte PORTC=7

byte count;

int buffer[3];

int i;

void detect_card();

void event();

void main()

{

   set_tris_d(0);

   set_tris_c(0b10000011);

   count=0;

   output_low(PIN_C2);

   delay_ms(1000);

   output_high(PIN_C2);

   output_low(pin_b0);

   output_LOW(pin_b1);

   buffer[0]=0;

   buffer[1]=0;

   buffer[2]=0;

   do

   {   detect_card();

       printf("Hex: %X%X%X  ",buffer[2],buffer[1],buffer[0]);

       if(buffer[2]==0x7E&& buffer[1]==0x0D && buffer[0]==0x76)

       {

       output_high(pin_D0);

       delay_ms(5000);

       output_low(pin_D0);

       }

       else

       {

         output_low(pin_D0);

       }

   }while(1);

}

void detect_card()

{

      for(i=0; i<26;i++)

      {       while(input(PIN_C0)==1 && input(PIN_C1)==1);

               if(input(PIN_C0)==0 )

               {       if(i!=0 && i != 25)

                        {    shift_left(buffer,3,0); }

               }

               if(input(PIN_C1)==0)

               {        if(i!=0 && i != 25)

                        {shift_left(buffer,3,1); }

               }

               delay_us(500);

      }

}

B0= output relay to start motor run, B1= output relay to buzer that shows wrong card

When touch card for one time, b0 will count 1, b0 will high

When touch card for two times, b0 will count 2, b0 will low

When another touch card will identified, b1 will high for 5 seconds and then will be low

DESIGN, EDIT AND CONSTRUCT

WEEK 5

Throughout this week, I only focus on constructing PIC circuit. Of course it is not as easy as A, B, C but since I seek helps from my friends, I am able to construct the PIC circuit within one week. At first I doubt that the PIC circuit will work correctly, but after do try n error,i finally success in constructing it. The circuit work fine and hopefully there will be no error afterwards. This PIC circuits is interface with the RFID reader, solenoid and will be display at the LCD.

Below is the PIC 16F877A circuit:
