ARM 7 - your comments please!

Started by ARM7 August 11, 2006
Hi group,

I am new to ARM7 microcontrollers and would like to hear from
experienced people what they recommend. I saw that the Philips ones are
pretty popular but ST have a built-in 1.8V regulator. What chip would
you recommend?
Are there any ARM7 with more than 64KB Ram and 1MB Flash?
I am not very keen in soldering - in fact I would prefer a ready made
and pretty small board with a chip on it so that I only need to add
power to get my first project going. Perfectly it should have a mounted
graphic LCD module and if possible 128KB Ram and 4MB Flash or more.
How good is the gcc compiler tool-chain for the ARM, code density etc?
Does everything work as expected? How about malloc and related
functions? Does the C++ frontend work for the ARM? As a fan of Modula
- I couldn't find it - any project with a Modula compiler?
Anything else you may want to share?

Best thanks in advance!

Try http://www.gnuarm.net/ArmDevices_frame.html http://www.arjay.bc.ca/Modula-2/m2faq.html There is a gnu Modula-2, but for a larger user base, you might want to look at the FreePascal ARM efforts, http://www.freepascal.org/wiki/index.php/GameBoy_Advance -jg

That is sensible. It is not realy worth making your own board these days. Gone are the days of MCU in 40 pin DIl sockets.

Buy a kit! Why do you need so much memory? What is the project
>How good is the gcc compiler tool-chain for the ARM, code density etc?
Not that good compared to the commercial compilers. (I assume you mean C or C++) However if it is for your own use it is OK.
>Does everything work as expected? How about malloc and related >functions?
A lot of embedded coding standards prohibit the use of Malloc.

Whilst Modula is theoretically a good language finding a good implementation is another matter. Also I think you will find that 99% of the support for ARM will be in C or C++ Certainly all the free examples from the chip vendors. Your ]best bet is to buy a dev kit. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ /\/\/ chris@phaedsys.org www.phaedsys.org \/\/\ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

AT91FR40162. 2 MB Flash + 256 kB SRAM in a BGA package.

None of us are with a BGA!!! :-)

For a first project that is a good idea.

Why so much for a first project? -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ /\/\/ chris@phaedsys.org www.phaedsys.org \/\/\ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
