How to read data from adc0804 to fpga

Hi guys I am beginner in FPGA. I have adc0804 in my circuit. And now I don’t know how to read the data from the adc and store the data on FPGA. I chose to use altera de2 115 board for the FPGA....

adc0804 has a very simple parallel interface.

For you purpose you can connect the CS pin to ground and DBn, WR, RD pins to any GPIO your board exposes (mind the voltage level compatibility).

Then you pulse WR and RD signals to convert the analog data and read the digital value on DBn.
