Evaluation Boards - Keil vs. IAR - ooggie01 - Jul 16 18:01:30 2008

I'm looking to buy an ARM development board for random hobby projects
and to eventually make a robot. I've found some boards that I think
will suit my needs, but I can't decide between a Keil or an IAR board.

Here are the boards I'm considering:
http://www.lpctools.com/index.asp?PageAction=VIEWPROD&ProdID=143
http://www.lpctools.com/index.asp?PageAction=VIEWPROD&ProdID=109

The IAR board has more peripherals, yet it is less expensive. Is
there something better about Keil that warrants the higher price?

Any insight into what board to buy and where would be much appreciated.

Thanks,
Thomas

RE: Evaluation Boards - Keil vs. IAR - Michael Freeman - Jul 16 18:23:09 2008

IAR does not lock its JLINK to their tool set. Keil forces you to use their
tools. So if you get a JLINK with either of these dev kits. I would choose
the IAR one.

Re: Evaluation Boards (what about Olimex?) - ooggie01 - Jul 16 19:14:31 2008

Oh, excellent suggestions. I quite like the first one
(http://www.sparkfun.com/commerce/product_info.php?products_id=3D8280),
but it's out of stock at SparkFun. It seems I can purchase the same
board for the same price here:

Re: Evaluation Boards - Keil vs. IAR - Danish Ali - Jul 17 3:59:48 2008

You asked
> Is there something better about Keil that warrants the higher price?

>From my (limited) experience, Keil puts a lot more effort into
generating sample code for all the different variants and their
peripherals.

So you'd be able to get going more quickly with Keil.
It is a trade-off of time vs money.

It takes a moderate amount of effort to port their sample code
to other development environments because they make use of
language extensions which are not present in competitors'
compilers (although equivalent extensions generally exist).

What did I do?
I bought a Keil demo board to start with, but when I outgrew
their demo compiler I switched to Rowley Crossworks rather
than upgrade to the commercial Keil compiler.

Danish
