    HI,

     

           I tried to implement the circuit but  was unable to get any message on the LCD. Also I did not clearly understand how the initial setting of the circuit is done i.e connecting P3.3 = 0 and start =0 and setting hour and minute and then removing them. Please help me as I am trying to implement this from a long time and seem to be getting nowhere :(

     

     

    Also is a picture of the microcontroller board that I am using. There is no availability of connection from pin 30 so I have soldered a wire to the board. But there is still no display on the LCD but the gree LED on the board flickers. What does it stand for?
