Started on LCD display. Faced many problem. Spent whole of the morning on debugging but couldn't fix it.
Put it off for later and took auto calibration function. The maximum voltage is accepted from the user and th reference voltage is stepped up slowly till the given output voltage is reached. While setting up the circuit it was found that the negative terminal of hte reference voltage is at same potential as of the positive terminal of the power supply. Hence we could not establish a common ground.
