Hi!
I'm getting stock on creating a LUT for waveform in this case sin wave. I am posting here to get other people opinion and perhaps some help on getting the values.
I have doing some code using a sin function, but I am at trying to do it with a ROM table.
I have manage to get in excel values from angle to normalize value to -1 to 1 but what about when I want to refer it to let say 2.5V.
Let amuse we have 10 bits and we have 100 Mhz clock.
Could you please help with your opinion, formula, example (ideally VHDL)?
Thanks
