help needed in understanding some steps [1 Attachment]

Started by kamran khan July 27, 2009
Hi,

I am new in DSP field. I am using TMS320C6713 starter kit to
generate signals up to 1 MHz using 5-6K interface board and DAC8581 EVM. The
software utilized is Code Composer Studio V3.1.

In order to grasp the basic concept of interfacing, i am trying to understand the sample code provided by TI for interfacing of TMS320C6713 with DAC 8831. Please find the sample code attached.

I am facing some silly problems in understanding the sample code
files. It would be nice of you, if you could please guide
me.

1). How is the configuration file (.cdb ) for a particular DAC
and DSK created?
2). For a particular DAC and DSK (in this case it is DAC
8581EVM and C6713 DSK) in .cbd file what parameters are required to set and how
it is done.
3). Besides .c (main) file and .cbd (configuration file)
there are various other files present in the folder.... how are these
files created.
4). In interfacing TMS320C6713 with DAC8581 EVM what necessary files are required to be included in the main project file.
Thanking you in advance and hoping a early reply.

Regards,

Kamran Khan

One thing to note is that your project was written for Code Composer
Studio version 2.21. You will need to do some work to get to "ground
zero" [a good beginning].
The following may help to give you some basic understanding and
familiarity with the tools.
1. Familiarize yourself with DSP/BIOS tutorials [build, run and modify].
2. If you are not using CCS v2.21, you will need to understand the
differences between the CCS 2.2x and 3.3x DSP/BIOS configuration.
3. Check the following links for some useful [hopefully[ info
