ARM Cortex-M0 on thin board

Note: This was originally posted on 23rd February 2012 at http://forums.arm.com

Hello to all

This is my first post - I'm looking forward to talking to all you guys.

I'm not too familiar with this aspects of embedded devices so this might be a basic question about the M0 - I'd like it to fit on a 3'' x 1'' board but the boards I see online - for example on here http://www.keil.com/boards/cortexm.asp - are all 3'' x 3''.

Am I missing something....?

Thanks

Hi nchaud and welcome,

If you are looking for something smaller on the ARM Cortex-M0, may be you will like the new mbed.
http://mbed.org/hand...icrocontrollers

Anything special you want on your board?

Kindly,
Alban

Beside from mbed.org, there are quite a few.

For example,

Thank you for the replies guys, really appreciate it

I'm actually looking to connect a CMOS image sensor to it (a small one - probably about 10mm x 3mm) and then to store the capture on some flash (and transfer off via USB later).

Perhaps taking a step back, do you think the M0 is still the best option for this?

Many Thanks
Regards,

It depends on what type of data processing your need to run on the microcontroller.

The Cortex-M0 is well capable of doing general data processing. But if you want to handle image data compression, you might want to use Cortex-M3 for additional instructions on MAC, hardware divide, bit field processing, etc. Or you can even use Cortex-M4 if you want to have faster DCT (it can run faster due to the SIMD feature). The CMSIS DSP library can run on Cortex-M0, Cortex-M3 and Cortex-M4.
