i am also having the same problem…….
when i program the LCD then correct alphabets are not displayed……….some symbols or unwanted alphabets are produced on the screen..
and i am also havin the problem in delay…… i.e. if i give a delay of 1000ms then the LED lights up for more than 6 seconds….actually i am not using any oscillator in my MCU ..does that create the problem
