09 May 2007 6:41 Debugging using scope

Hello,
I am new to Embedded and currently writing a driver for an embedded processor. I would like to know how to use Oscilloscope to debug the target board. I was first asked to check the clock signal, chip-select signal using a scope. Since I am a software engineer, dont know how to use scope.

Can any one help me? Probably links, resources and tips debugging with scope.

Thanks,
Kars

A quick Google search on "using oscilloscopes" brought up 803,000 hits - here are a few of the first:

I've got several 'scopes and use them often. Very useful machines!

Good luck

Many ways to debug a firmware depending the specific project you are dealing with. I am a electronic engineer before a programmer, and rarely use oscilloscope for that purpose.

However you are talking about scope, so before talking about how to use the scope, first let's talk about which kind of it you have, or any idea about choosing a right scope for you?

In my opinion, the most suitable affordable scope for this purpose is the 2-channel analog one. If you can buy the better, think of the 2- to 4-channel digital scope with memory and PC communication capability, it is really helpful tool.

How do you think? And we will continue discussing later.

Hi,
Thnaks to all for suggestions.
I have Digital Storage Oscilloscope : Tektronix TDS2024.

Now I learned that I will have to look at the schematics to find out where the pin is located on the board.
