 |

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 |

Well, you should know the type of processor, pic/arm/avr so just |
googleit
It should not take more than an hour.
There are thousands of links, then refine your question

You should change careers, probably to financial advising. I don't want a
newbie like you working on a consumer appliance that I end up buying.

What an attitude. 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.

There's lots of stuff online, just takes a bit of googling. 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.

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.).

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.

Huh? 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. |

Whenver I am in need for an embedded programmer I look for people who
understand the hardware around the uC, have a basic graps of what
production folks like and don't like (testing, debugging) and most of
all can spot potential situations where something could go kablouie in a
spectacular fashion. We try to avoid anyone who says "that's not my turf".

Hi Mike,
I truly appreciate your help and comments you posted. This makes me
feel better when I see there are only few weirdos like Lizard (end of
the names!) in this group. Anyway, to make long story short, as I said
I'm very interested in embedded and high speed design that is why I
switched to electrical engineering in master degree now looking for an
opportunity. I have done design/programming in FPGA on Altera DE2
boards and SOPC Builder (for using C) and and currently working on
Xilinx (Spartan 3E).
In past had some experience with 8051 but recently have bought ARM
board but yes everyone points to AVR as a good board to start.
However, I have done mostly digital things not that much analog but
planning to switch to that concept at well.
One thing I need to mention is that English is not my native language,
it is the 3rd language I have learned so I'm not sure why this thing
(lizard) is annoyed that much but in general I guess have to let it
go ... so the only advice I will have for Lizard it just keep playing
with your cats! and do not jump in people's discussion. |

Yeah, that reply was not helpful - some people are like that (or
they're just having a bad day). Anyway, the AVR would be a good chip
to start with. The folks at www.avrfreaks.net are very helpful, and
there are lots of tutorials on the site. So work with the AVR and
then when you think you're ready work with your ARM board as well, and
you'll be off to a good start. Best of luck.

Lizard-like things abound on Usenet. Simply ignore them. If you
get off google and use a real newsreader (and newsserver) you will
have the ability to PLONK them, so you won't even see any further
annoyances.
