I'm a newbie using spartan 3E development board (XC3S500E-4FG320C).

I'm intending to display ADC code on LCD but it'll be like for 0000 0000 0001, display 0.00035V or -60dB.

How can I do this in VHDL? or need to use EDK/SDK?

Thanks.

Added after 2 hours 24 minutes:

actually there are about > 4000 values to dispaly. If I use a case, for X dislplay Y, it may take very long. and if I don't think that can use for loop (like--> for i =0, i<4096, i ++, then display....) as my answers in dB is not an incrementing value. basically i need to declare the LSB= XXX then 20*log (A/B).

Any suggestions?

Thanks.
 

You need to store the data into the memory and then scroll the data out to the LCD using an input to show different values.

Don't need a loop, just a simple control to know how big your LCD is and how to pick up the data from the memory and show it on the screen.
