Displaying character.

I am not sure what you want to do, or how lcddata() works changing 'c' to "c" may help.
It appears that you want to call lcddata() until you get a null ('\0')
Other wise you are getting the data from Code address 99d then writing until you find a zero in memory

void lcdwrite(char *letter)
{
  while(*letter)
  {
        lcddata(*letter);
        letter++;
  }
}

void main()
{
  Init_Device();
  lcdinit();
  lcd_clear();
  lcdwrite("c"); // This maybe right
}

I change name and code to this:

void lcdwrite(char diget)
{
  while(diget)
  {
        lcddata(diget);
        diget++;
  }
}

now i get a different characters on screen.

what else can i try?

How do you suppose that will work?

Think about what the 'while' will do...

"what else can i try?"

Look back throughh this thread, and think about what "null-terminated string" means - look it up in your textbook, class notes, etc...

Now who's using my new nick or trying to be me?? I didn't wrote that...I am Fitri Nickolasky aka Fiddy Geeky...

Guys,just wanna check with you guys whether Did i configure the ports correctly??I connected the following pins of my LCD to 8051: RS to PORT 2.5, RW to PORT 2.6 ,E to PORT 2.7 and my data pins to PORT 3.0-3.7...

void Port_Init()
{
    PRT3CF    = 0xFF;
    P2MODE    = 0x1F;
}

Fiddeley,

WTF is the PRT3CF register?

youre usin an 8052 not an 8051. neither has the PRT3CF or P2MODE register.

youre project is now late mate!
