Hi,
I have managed to do my LCD code and the code is as follows :
#include <p18f452.h> /* for TRISB and PORTB declarations */
#include <xlcd.h>
#include <delays.h>
/* Set configuration bits for use with ICD2 / PICDEM2 PLUS Demo Board:
* - set HS oscillator
* - disable watchdog timer
* - disable low voltage programming
*/
#pragma config OSC = XT
#pragma config WDT = OFF
#pragma config LVP = OFF
//void sendCmd(unsigned char Cmd);//write command to lcd
void sendData(unsigned char Ch, unsigned char rs);//write text to lcd
void initializeLCD(void);
void main(void);
void lcddata(char);
//PORTC RC7 RC6 RC5 RC4 RC3 RC2 RC1 RC0 *
//Data Bus D7 D6 D5 D4 D3 D2 D1 D0 *
//PORTD RD6 GROUNDED RD7 *
//controls RS RW E *
//**********************************************************************
#define RS PORTDbits.RD6
#define E PORTDbits.RD7
void sendData(unsigned char Ch,unsigned char rs)
{
LATC = Ch; //send 8-bit data
RS = rs; //control RS
E = 1; //pulse E
Delay10TCYx (5); //wait 50 us
E = 0;
Delay10TCYx (5); //wait 50 us
return;
}
void initializeLCD(void)
{
Delay1KTCYx (40); //wait 6 ms
sendData (0x30, 0); //send 0x30
Delay1KTCYx (10); //wait 6 ms
sendData (0x30, 0); //send 0x30
Delay1KTCYx (10); //wait 6 ms
sendData (0x30, 0); //send 0x30
Delay1KTCYx (10); //wait 6 ms
sendData (0x38, 0); //send 0x38
Delay10TCYx (8); //wait 50 us
sendData (0x01, 0); //send 0x01
Delay1KTCYx (5); //wait 2 ms
sendData (0x0C, 0); //send 0x0C
Delay10TCYx (8); //wait 50 us
sendData (0x06, 0); //send 0x06
Delay10TCYx (8); //wait 50 us
return;
}
void main()
{
// CMCON=0x07;//RA),1,2,as input/output
unsigned char a=0;
TRISDbits.TRISD6=0;//set output;
TRISDbits.TRISD7=0;//set output;
TRISC=0;
initializeLCD();
sendData('C',1);
sendData('O',1);
sendData('R',1);
sendData('R',1);
sendData('E',1);
sendData('L',1);
sendData('A',1);
sendData('T',1);
sendData('I',1);
sendData('O',1);
sendData('N',1);
sendData(' ',1);
sendData('I',1);
sendData('S',1);
sendData(' ',1);
while(1);
}
But now I'm stuck at a stage where I need 2 do CORRELATION of 2 sample waves and show the value of Time Delay on the LCD.
I have done the CORRELATION code in separate and it works properly but I'm facing problems when I add my Correlation code in the LCD code.
That's my Correlation Code:
#include<p18f452f.h>
#include<mathf.h>
#include<stdio.h>
#include<stdlib.h>
#include<xlcd2.h>
#include<delays.h>
#include<usart.h>
void DelayFor18TCY(void)
{
Nop();
Nop();
Nop();
Nop();
Nop();

}
void DelayPORXLCD (void)
{
Delay1KTCYx(40);
return;
}
void DelayXLCD(void)
{
Delay1KTCYx(10);
return;
}
void main(void)
{
unsigned char x[]={0,0,0,0,0,0,0,0,0,1,2,3,0,0};
unsigned char y[28]={0,0,0,0,0,0,0,2,3,4,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
unsigned char Rxy[13];
unsigned char n[13];
unsigned char i,j,k,l;
for(i=0;i<=12;i++)
{ Rxy
=0;
for(j=0;j<=13;j++)
{Rxy=Rxy+x[j]*y[i+j];
}
}
for(k=0;k<=6;k++)
{Rxy[k]=l;
Rxy[k]=Rxy[12-k];
Rxy[12-k]=l;
}
OpenXLCD(EIGHT_BIT & LINES_5X7);
putrsXLCD( "CORRELATION IS" );
while( BusyXLCD() );
SetDDRamAddr( 0x12 );
for (i=0;k<=12;k++)
{
WriteDataXLCD(Rxy);
//WriteCmdXLCD(SHIFT_DISP_RIGHT);
}
}
Please can you let me know if you can help ?
PLEASE I NEED HELP ASAP....
