I'm going through my university assignment and got stuck here. Help needed asap as due date is near.
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,

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.
