has anyone worked on those chips? they are the next gen from the ARM7/ARM9/ARM11 series and seems to be much faster than ARM7, and spans a wide performance spectrum.

I am thinking more about the lower-end chips (Cortex-M3) than the higher end chips.

Any thoughts?

Worked on certainly covers quite a bit of ground. I've read the data sheet and I'm considering one for an application. Does that count?

heh i think it depends on what your making. those kind of chips are are best for like RTOS (real time operating systems) .

So yeah it depends on what you intend to use it for. Its a beautiful piece of hardware tho. If i was familiar with ARM and all this embedded stuff more i guess i would tinker with it

they just seem to offer a lot of performance for the money: a 60mips (1.25mips / mhz @ 50mhz) chip for less than a dollar. That's pretty amazing.

What quantity do you need to get them for $1

AtomSoft · 20th June 2009, 04:46 PM

if i can get them for a $1 then heh i would buy a bunch and not worry about it being a overkill. A overkill is bad when it cost more. Why pay for more when you can do it for less lol but if you get more for less then its different lol

Cheapest i found $2+

those are cortex-m3 chips in epoxy packaging, in 10k quantities, like you would have in a toy.

It's like winning the Scottish Lottery. You get $1 per year for 1 million years.

Im thinking about starting with the ARM7 and staying there for a while

Digi-Key - 568-2093-ND (NXP Semiconductors - LPC2102FBD48,151)

seems like a good IC to use alot... of course ill start with a dev board tho. But when i do need to create something im sure that will fit in the requirements... if not there are a ton more and all are about same price as PIC.

I know there isnt alot of support for ARM7 like PIC here but im sure ill learn alot and help alot.

GREAT PLACE TO START:

This is better tho:

millwood · 20th June 2009, 09:40 PM

jason, that looks like a nice chip.

as to boards, how about this one: http://www.sparkfun.com/commerce/pro...oducts_id=259?

it is based on lpc2138, a chip more capable than we will be able to exhaust.

AtomSoft · 20th June 2009, 10:25 PM

you mean :
SparkFun Electronics - Terminal Development Board - LPC2138

also i wanted this one:
SparkFun Electronics - Development Platform for LPC2378

but might choose:
SparkFun Electronics - Prototyping Board for LPC2148

Futz was using the LPC2148 board and he has some code on his site so im sure i can learn from there too!

dknguyen · 20th June 2009, 10:28 PM

They aren't "nextgen" per se. They are more like the ARM series but designed from scratch to be a microcontroller rather than a microprocessor. The M3 is the equivelant of the ARM7, and so on and so forth. I'm planning to use the M3 for the next thing I build because of the packaging and the programmer and IDE can be had for a fair price.

millwood · 20th June 2009, 10:44 PM

jason: they all look like great mcus.

dknguyen: which programmers are you thinking about? I am new to this jtag thing and haven't had it all figured out.

millwood · 20th June 2009, 10:45 PM

I thought on architecture basis, cortex (harvard) is quite different from arm7 (von neumann). cortex (m3 at least) doesn't run the full arm instructions but just thumb(2?).

I am just amazed at how much more you can get out of those chips.

AtomSoft · 20th June 2009, 10:53 PM

As for a programmer to begin with im getting:

SparkFun Electronics - JTAG USB OCD Tiny - Programmer/Debugger for ARM processors

The Ulink is too much money lol
