design expination

hi...i am working on design and development of low cost ARM cortex M3 based evaluation board.i download schematic from keil website.but they are not providing explination about circuits.i want full discription about circuits of development board.

please see below attachment in that circuits are their i want explination about that.

There is no board schematic in the power point presentation you posted.

I've seen quite a few dev board schematics and user manuals and detailed descriptions and explanations are not common.

You may need to do a lot of Googling and research.

If you have any specific questions please post a schematic and I and others will help.

Sorry lavanya - you are going to have to do a lot more on this yourself - there are dozens of schematics on Keil's website - you could at least tell me which one you can't understand.

There is only one schematic in the presentation and it seem sto be some kind of audio driver with no obvious relevance to ARM Cortex.

Is the presentation the task information given to you for this project ?

I'm not sure how you think I could help you - if you've left all this to learn about until 36 hours before a test then there is nothing I can do to make up for that lack of effort on your part.

Rather than asking me to do the work for you I suggest that you get Googling - you've given me a list of key words - use it. If you keep at it non-stop and get lucky you might scrape through.

If this seems unkind or unhelpful it's because I know that some time in the future you'll be up against people who have done the work.

As ever, if you have a specific question about something you can't understand I'm sure some one on E14 will help.
