which ARM derivative to start with???

[deveshsamaiya]

hello everyone...

I need to start my development work using ARM series of microcontrollers. When i was searching for some suitable options i found some versions available in local market.

• LPC21xx by NXP
• AT91SAM series
• AT91rm9200

Please anyone tell me which one of the above will be best to begin with. Criteria of choosing a particular are
1. Open source support
2. Internet support community
3. Tool chain support by manufacturer or by community
4. Cost

Hi

Do you want to stick with ARM9 or an ARM7 would be ok ?

[deveshsamaiya]

that is what my confusion is, i need to develop wireless sensor network applications. Which will be suitable, both are completely new for me.

I am not sure to be able to help you because your request has a little bit wide spectrum but I use an ARM development board from Olimex. The tool chain I use is the gnu arm gcc compiler and gdb with OpenOCD. All is of course Open Source.

This Olimex dev board (not the one I use) has a wireless transceiver : http://www.olimex.com/dev/pdf/ARM/ST/STM32-103STK.pdf listed at 80 euros

Hi

The ARM7 and ARM9 are a bit old micro

Use the new cortex M type like the STM32,LPC17xx,LPC11xx,LPC13xx,SAM3U,EFM32,S1M32

Low cost eval board available from olimex and for more lower cost there are some Chinese manufacture

for free Tools you can use the GNU compiler or down load limited version of the IAR or KEIL compiler(prefered)

All the best

M3 i think ARM7, M0 would be ARM6.

Embedded Artists just relreased their LCP-1768 LPCXpresso board quite cheap - 20 Eur

NXP uses Code Red as compiler/debugger for their Xpresso boards , but the free version it's limited to 128K.

But the Xpresso boards comes with a build-in debugger on the board.

It's a nice value for the money 512k-Flash 32K-Ram
And one can make quite a lot within 128K.

Else there is the Olimex LPC1343 for 13 Eur

lpc is the best

HI

For wireless sensor the STM32 ARM cortex M3 is the best

A well supported & documented micro with a lot of application note and code sample (important for every beginner)

And soon will be available the STM32L for low power application about 320uA@mHz

All the best

Does anyone have Coretex M0, M3 ASIC cores they can share?
