Hi all
hope this routines will be helpful for the beginners.

/* this routine will print the hex nos in lcd directly*/
void hex2lcd(unsigned char hexdata)
{
unsigned char MSB,LSB;
MSB=((hexdata&0xf0)>>4);
LSB=(hexdata&0x0f);
if(MSB<0xa)
MSB=0x30+MSB;
else
MSB=0x37+MSB;
if(LSB<0xa)
LSB=0x30+LSB;
else
LSB=0x37+LSB;
lcd_data(MSB);
lcd_data(LSB);
}

/* this routine will print the decimal equivalent for the hex nos in lcd directly in the format "X.XX" */

void hex2dec2lcd(unsigned int hexnum)
{
unsigned char t=0,u=0,v=0;
h=0;
while(hexnum>=100)
{
h=hexnum-100;
t++;
hexnum=h;
}
while(hexnum>=10)
{
h=hexnum-10;
u++;
hexnum=h;
}
v=hexnum;
lcd_data(t+48);
lcd_data(46);
lcd_data(u+48);

}
