Hello,
having just started using AD9910 board, I got stucked with RAM usage. I know how to load/retrieve data from RAM - the problem is, I do not understand how to create a suitable set of data. Having read the datasheet, technical tutorial, user guide and searched on the Internet, I made only little progress.
From the data sheet (p. 33/60, Table 12) I know the required structure of each word and how many bits are assigned to each parameter for each type of entry. However, I have no idea what to put into those bits. The first thing that came to my mind - to load the required values of, for example, frequency - does not seem to be right, especially after having a look at several example files posted on this forum.
Therefore I would like to ask you, how can I create files for AD 9910 RAM - what are the general rules, if there is any software required etc.
I am especially interested in a way how to get data from Excel/Calc and txt files into a format suitable for the RAM.
Thank you very much in advance.
Dear Kevin and Ken - thank you very much for your help, I think you told me just what I needed to know. I will give it a try as soon as possible and let you know if I will be still having any problems.
(Rather unfortunately, I apparently can't give 'correct answer' points to two different people at once, so I had to spread the points:)
