Hi Rao,

on most ADC / DAC data sheets there are also connections sheme to a microcontroller included. So nobody want to do the job and read the data sheet for you.
If you tell us the manufacturer and name of your adc, dac, lcd and have luck, that anybody use it also, then maybe he give you the code.

But nevertheless without reading the data sheets carefully, I'm really in doubt, that you can finish a working project.
