RAM to generate Waveform signal - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi all,

I have an analog device dual DAC with on-chip RAM.

This RAM can be wrote with the SPI port and the data are coming from a file.

The reference of the component is AD9788 :

The purpose of this RAM is to replace the data input of the DAC.

My question is, How i have to program this RAM if i want to generate a signal ?
I know nothing about RAM and digital data

Thank you for your help, does anyone have an idea ?

Guillaume
