ARM Microcontroller - Tempting?

[Maverickmax]

Hi

I am considering of buying ARM microcontroller because I need the processor is capable of implementing complex calculation such as digital/kalman filter and other complex math implementions.

My burning questions are:

1) Is there "free IDE with no limitation" tool for me to programme in C?

2) Where can I buy it? It must contain a chip with two crystal oscillators for uc and RTC with pins.

3) I would love to get hold of the cool ARM. Know which one?

4) ISP tool to buy?

Thank you very much guys

MM

There is WinARM which is the defacto standard for ARM Programming.You can use it with Eclipse just google it.Also there are lots of ARMs that have inbuilt RTCs.The most popular ARMs are made by NXP.They are the LPC Series.I recently saw a board on the Internet for your requirement.It is pretty good to get started with.

If you'd rather buy it you can go to

https://www.olimex.com

They are very famous.I suggest you join the LPC2000 Group on Yahoo.There are a lot of boards and other references there.Good Luck.I am also learning ARM s.

Have you considered a real DSP like the Analog Devices Blackfin processor ( https://www.analog.com/en/embedded-processing-dsp/blackfin/processors/index.html )? I worked for a company that used this processor for kalman filtering, so i think it's good at it. Most ARM microcontrollers do not have DSP features that you might want to have for heavy calculations

The ARM Cortex-M3 processor, the first of the Cortex generation of processors released by ARM in 2006, was primarily designed to target the 32-bit microcontroller market. The Cortex-M3 processor provides excellent performance at low gate count and comes with many new features previously available only in high-end processors.

Tthe Cortex-M3 processor is not the first ARM processor to be used to create generic microcontrollers. The venerable ARM7 processor has been very successful in this market, with partners such as NXP (Philips), Texas Instruments, Atmel, OKI, and many other vendors delivering robust 32-bit Microcontroller Units (MCUs). The ARM7 is the most widely used 32-bit embedded processor in history, with over 1 billion processors produced each year in a huge variety of electronic products, from mobile phones to cars.
