Is there a particular reason to use PIC?

I suggest Atmel AVR gives better performance and also better value if
you have any significant production run. Another reason I reccommend
to use AVR is that they tend to perform much better if using C
compilers.

Johnny.

PIC chips ..... no not really. The project is to interpret CANBUS signals
into alternate outputs.

6 of one, half a dozen of another. Each has it's good points, each has
it's bad points. Add to that list Motorola, Zilog, NEC, Renases blah
blah blah. The one who says the AVR is better than the PIC or vice
versa without taking the job into consideration is a fool.

BTW, having used all of the above, I can confirm that the PIC does
provide equal performance, if not better under specific conditions. I
can also confirm that the PIC performs equally as well with C
compilers, providing that you use a decent compiler.

But, to look at the application that the OP is suggesting, there is a
lot better options than either PIC or AVR. I would suggest looking
into the new fujitsu controllers. Alternativly, I would also recommend
looking at Hitachi and Motorola as these companies have a good track
record in automotive applications.

Tou are right about taking the application into account, but I
personally can't see any good reason to choose PIC in preference to
AVR for a new design. I think that PIC were very innovative about 10
years ago, but now with the availability of AVR at competitive prices,
its makes PIC look very over-rated. They tend to be a bit expensive
for what you get.

If you need one or more CAN ports maybe Motorola might be a better
choice, but development tools will cost a lot more. There is a very
new AVR processor with a CAN port so personally I would be looking at
that as one option.

Johnny.

I was hoping someone would look into it for me.

My (company) going rate is $120/hour. Can you afford that?

Does that include arse scratching and coffee or is that just for coding and
design.

I have some very experienced developers in my SimmStick chat group that
may be able to assist.
If you wanted to send me a quick writeup on your application, I will
post it to the group.
I feel it just needs a little more info than the message you posted
here.

Cheers Don...

Hi Don,

I dont think it HAS to be Sydney based but I would like someone to feel that
they are working in a team and that they will be making a gainful
contribution to themselves.

Small business dont participate in arse scratching and coffee drinking
unless it can be done sucessfully and productivly alongside your work.

My business partner is the one who does the quoting, based upon what
is involved in the job. We usually steer away from hardware and focus
on software, but I will do anything if someone is willing to pay.

My point was can you afford a professional company (I am cheap,
believe me) or are you looking for a uni grad to do work on the cheap?

Or you could be looking for a uni undergrad(like me, final year). Much
cheaper than a full uni graduate. :p

BTW. I'm a undergraduate final year electronic engineering/commerce(finance)
student. My engineering marjors are communications and signal processing, I
am still looking for some more work experience, willing to work for a pitance.
I'm in Perth.

How about a one man company that doesnt need to have sales meetings.

That would be a back yarder then? Or a uni grad?

BTW: I am in a 2 person company. Our rate is much cheaper than most. I
have seen upwards of $250/hour.

Hello Miro,

It's always nice to be optimistic but how much per hour do you really
think is acceptable for what you wish to achieve. This may not be the
80's however you are asking for a hardware and software solution for
an automotive application. Do you have any idea of how harsh this
environment can be??? - if not I suggest you do some serious research
on this topic. I have personally seen many designs that work fine on
the bench or in the lab and then fail miserably when introduced to the
automotive environment - believe me, this is not for a newbie or the
faint of heart if you want a reliable product.
A person or company that specialises in products for this environment
does not come cheap if you want a reliability.And sorry, no offence
here, but an undergrad or fresh grad does not have the real world
experience to provide what you want. There is no substitute for
experience here - it can mean the difference between product viability
and total disaster.
Anyway that is my 2 cents worth - don't say you weren't warned!

I must say I have done some work on the UWA motorsport team and I can
appreciate the amount of electrical noise that is present in the
environment. It was hell trying to get even a steady power supply. It
too 4 of us a whole weekend to figure out that was the cause of the
continual resetting of the microcontroller. Some more experienced prolly
would've pick that much quicker. Moral of the story unless you have a lot
of time and are really cash straped, I'd find someone experienced in this
field. Personally speaking I feel that given enought time someone like
myself would eventually produce something working but it would take much
longer(prolly 2 to 3 times as long) as someone more experienced. BTW
although I am an undergrad, I've effectively finish all my engineering
already. This year I'm just working on my project(a low noise preamplifier
for infrared photodiodes operating at cryogenic temperatures) and finishing
off my commerce units. Oh yeah, I'm still looking for some more work
experience, will to work for a pitance or for free(depending on size of
job and out of pocket expenses).

Did anyone even bother to read my post where I mentioned CAN. The first test
is comprehension, which it seems most havae already failed.

Thanks to all those that replied. I found someone in Sydney. I already have
the chipset, proto, pic code in hand. All I wanted was someone capable of
updating the code and knocking out some new pcb's.

The person I have struck a deal with isnt cheap, but then he understood the
project and the fact it was well advanced.
