use this code (ccs) its very simple. first add this func. nokia_init(); and nokia_gotoxy(8,2);  set pozition printf(nokia_printchar,"sonsivri"); send your text. i tested this driver its working good  Wink

and for put something on lcd,
on your main:
Code:
.....
   NOKIA_INIT();
   NOKIA_GOTOXY(0,0);
   PRINTF(NOKIA_PRINTCHAR,"SOMETHING");
   NOKIA_GOTOXY(0,2);
   PRINTF(NOKIA_PRINTCHAR," TO LCD ");
   printF(nokia_printchar," NOKIA");
