Newbie questions on ARM

I've never used ARM microprocessors, so i have questions about. For
now, i have only used 8 bit micropoccessors and i have programmed only
in C and asm language (i'm not expert in object oriented programming).
I shoud use an ARM7 microprocessor.
1)What is the best ide for software development?Any site, reference ,
comparative table, suggestion?
2)Any book about this micro?
I'm totally new, so any suggestion is important for me.
Thanks

You may try the YAGARTO toolchain: http://www.yagarto.de/
It includes Eclipse as IDE together with GCC and various other components.
It is free and works well.
I don't know about books but on the net there are a lot of examples and
support for the ARM7, here as example:

There is no universal best. This is something you'll need to research
to find your own feature, cost, performance, support, etc. balance.

Hitex has a nice introduction to the Philips/NXP flavour linked from
their main site at http://www.hitex.co.uk/.

You should be aware (if you're not already) that the ARM families from
different manufacturers have significant differences in their
peripherals -- where peripherals include things as fundamental as
interrupt controllers.

For compilers, if your project can use GPL code there's a
well-supported gcc port at http://www.gnuarm.com/.

On the commercial side, Keil is the Big Dog, and priced accordingly.
IAR, Rowley, and ImageCraft are other commercial players (I'm sure
there are more...). ImageCraft is where my price/performance curves
intersected; your mileage may vary.

This question comes up again and again, and the answer is really dependent 
on your own usage requirements.  If you can say more about:

1) How much you want to pay.
2) What sort of support you are after.
3) Size optimisation, speed optimisation, or dont care?
4) License model.
5) Documentation.
6) Reliability.

Then people may be able to make some suggestions, but be prepared for a 
religious argument as to the pros and cons of GCC which I'm sure will 
follow.

Eclipse is one solution if you want a free environment, but this is by no 
means the easiest for a novice.

> 2)Any book about this micro?

http://www.hitex.co.uk/download/con_download_insiders-guides.html for an 
intro.  If you are after a heavy weight reference then

http://www.amazon.co.uk/ARM-System-Developers-Guide-Architecture/dp/1558608745/ref=sr_1_1?ie=UTF8&s=books&qid=1212936508&sr=1-1

You might also like to look at the ARM Cotex-M3 as an alternative the ARM7.

Please note that using gcc does *not* automatically mean your code
comes under the GPL. The GPL refers to further distribution of the
compiler itself, not of your code.

If you link in other code (like e.g. newlib in the case of gnuarm)
then you will be subject to the newlib license conditions, but they
are much less restrictive for commercial use. You can keep your code
proprietary. And it is perfectly possible to avoid linking in *any* of
newlib by providing your own functions where needed. I find there are
very few of these in smaller embedded applications.

If you use the NXP ARM chips you will get plenty of support from the
LPC2000 Yahoo group.

Roger that. Trying to avoid the usual meta-discussion on the various
licensing issues, but that never seems to work. ;-)

If you want to do this for free, you can do this in 3 parts...

The compiler: GCC (gnuarm or similar),
The IDE: Eclipse (www.eclipse.org), or CodeBlocks (www.codeblocks.org).
The JTAG debug tool: Olimex, Amontec, Wiggler, all driven via OpenOCD. 
OpenOCD is a utility which drives the JTAG tools, and GDB makes a connection 
to it when debugging. (openocd.berlios.de)

We have developed a free toolchain, that pulls GCC compiler, our own IDE, 
and OpenOCD support.

www.st-angliamicro.com/software.asp

There is a free IDE, which is seperate from our build of arm-elf-gcc (sarm). 
Eclipse seems to be the popular choice at the moment for IDE's.

The above does not have simulation support though.


Commercial solution:

I have used Keil, IAR, and Raisonance. Keil has fantastic simulator. Around 
the �2.8k price for full, or around 1.2k for 256k baseline version. Pricing 
for these 2 are similar. Raisonance is a lower cost solution, around 600eur.

A good price version features IDE is Rowley (www.rowley.co.uk/).

Hi, you will find some comparisons between ARM devices, links to tools
and also some information on non-LPC on this website
http://www.lpc2000.com  be sure to check out the "other ARM7..." and
the "Development tools section.
