Hi,

What you need is two routines. One is a conversion table from the data you receive from ADC versus the data you want to display on lcd.
For example if your data 0FFh means 5V, you might need to show "5.0 Volts" and for example if your received data is 0FD, you might need to show "4.9 Volts". So you will have to make a code routine or conversion table for this. I can give you some idea for that, please send me mail if you need my help.

Number two is to initialize LCD and sending the data to LCD. This routine is also very simple to do. I do not know how much you know about LCD. Send me email if you need any help.
