How can one interface i2c and spi adc with spartan 3e fpga board?
download user guide and write the vhdl or u can download the adc vhdl file xilinx website
Firstly, check what is your adc output is, normally either "i2c, spi, or parallel".
Then, make the communication protocol in programming language such as VHDL.
And at last, follow the communication protocol that is in the adc data sheet to send and receive data from adc and use the data that you would like to.
Adding to all those who has answered already. You need to know what is the frequency at which you are receiving the data at your FPGA. How many bits of data are you receiving. i would suggest you to use a FIFO for interfacing so as to safely latch your data in to your system. If the frequency of sending and receiving domain are different then you might need to use an ASYNC FIFIO.. Hope this helps... Any more doubts are welcome..
