Draw a block diagram to interface an 8 bit ADC with 8051. Clearly show your calculations

and assumptions to use above DAC to set the ADC reference voltage 10 V and display the

result in three seven segment displays.

DAC discussed here is from the following question,

"The nbit R/2R digitaltoanalog converter (DAC) has a reference of 16 V and the analog

output for the input code 1 is 15.625 mV. Find the digital input value for the output

9.140625 V."

So far I have done following calculations and answersoutput for the input code 1 is 15.625 mV. Find the digital input value for the output

9.140625 V."

__Block Diagram__

__Calculations__

Output = 10V

Input = 10/15.625*10^-3 = 640

Input digital signal = 1010000000

I can understand that I have to send the input signal to the DAC discussed here using the 8051 and I can use Vout of the DAC as the reference for ADC

What I cannot understand is what is meant by displaying the value in 7 segment displays ( What do I have to display ? ) and what are the required calculations and assumptions.
