hi group, I'm on a transition from software to embedded software job. however, I haven't used things such as logic analyzer or analog boards for years. Now I need to fresh my mind and get some exprience on: layout, prototyping analog and digital circuits circuit schematic What should I do? how and where? any online resources? thank you, amit

I don't want a newbie like you working on a consumer appliance that I end up buying. That being said ... Depending on your educational background: a)You should probably take a few circuits classes at the local university. The trauma of doing homework, preparing for exams, etc., forces you to actually learn the stuff. b)You should probably review classic embedded systems problems (initialization issues, interrupt-related issues, design of sequential logic, etc.).

So I guess college graduates should pick a new profession. Everyone is a newbie somewhere along the way. That's what senior engineers/mentors are for. JW

That's what senior >engineers/mentors are for.Right now I'm trying to find homes for two feral kittens (fortunately, their behavior is greatly improved from a couple weeks ago). My two adult cats smack the kittens around just so they don't forget who is boss. Naturally, as the kittens get larger, this won't be possible any longer. I don't see any reason that human behavior should be any different. A post with the word "transition" in it asking for advice is really a request for abuse. The OP wants abuse, but doesn't quite know how to ask for it. I'm glad to accommodate. The Lizard.

One place that's worth a look is www.ganssle.com - lots of good articles there. So what should you do? Buy a board with an 8-bit processor like an 80C51 or AVR, install a toolchain, and do stuff with it. One reason I suggest an 8-bit device is that, coming from the desktop world, you need to have it sink in that most embedded systems are pitifully short of the speed and memory that you're accustomed to. I saw an example recently of a person who declared about a dozen text strings in an embedded program and ran out of RAM. What he needed to do was force the strings to live in flash or other program memory and only bring them into RAM when he needed them. This is just one example of the kinds of things you need to learn in the embedded world. Here's an example of the kind of board I'd recommend. It's got the obligatory buttons and leds, and it has an LCD display which I think is very useful to have and to master. http://eecs.oregonstate.edu/education/products/mega128.2/ Mike

What makes you think you need electronic hardware design or production skills to work on software? Yes, you should know how to understand schematics. But leave layout and production to the hardware guys.
