ARM SBC - grantpbt - Aug 19 18:14:06 2008
Hi,
I'm new to ARM, but very experienced 8-bit programmer. I am looking
for advice on which MCU and a cheap (<$200) single board computer that
can be used for a project in which an 8-bitter is no longer ideal:
- small graphic LCD (maybe QVGA or similar, don't care if color or mono).
- would like to add a touchscreen (can do ourselves but if there is a
controller onboard all the better).
- would like internal or external RTC for time-of-day purposes
(battery backed).
- two or more serial ports (for RS232), support for I2C and/or SPI.
- USB device.
- removable memory card/stick that can be plugged directly into a PC
(USB, SD, etc).
And here are some wish list items only for my education, so they are
not mandatory.
- Ethernet
- USB host
- Linux.
Any help you can provide regarding MCU or SBC would be appreciated!

Re: ARM SBC - stevech11 - Aug 19 23:06:57 2008
some suggestions to look at...
Coridium Corp's several ArmMite. Too small to grow to run Linux, but
using Linux takes a $200+ board as a practical rule. For hobby
purposes, just run embedded linux on an old PC motherboard!
Futurlec's ETT ARM boards from ETT.
ETT has a board not on Futulec's site, 2376 based, all the goodies,
very low cost. Futurlec can order it.
Olimex's boards are very popular. Resold by many including SparcFun.
IARs free demo compiler up to 32KB is good for starters.

Re: ARM SBC - grantpbt - Aug 20 11:41:32 2008
Thanks all for the tips! I'm sure my mind will change again, but so
far the Sparkfun boards (Olimex, etc) and the Embedded Artists boards
look the most appealing to me. I want something that I can program in
C (not Basic) so I also need to learn about GCC, probably on WinXP (I
did Cygwin many, many years ago... is it still happening?).
I also want the ICP/ISP to have as little impact on my code and
hardware as possible. I don't mind dedicating a header and a few pins
to ICP as we do that with the LPC9xx and C8051F34x chips already, but
I don't really want to give up a UART if I don't have to as the end
application needs 2 of them.
Also, is there open source or freeware FAT code for SD/MMC/etc? I
need some kind of removable media that a PC can read and I understand
that writing a FAT16 or FAT32 is not something I want to take on at
this point.

M$ has a patent on the FAT file system (challenged and withdrawn by
the patent office, but upheld on appeal, and is currently being
litigated, afaik). If you are in a country that allows software
patents, you will be in deep trouble.

I was under the impression that the Microsoft patent relates to use of
long filenames in FAT32 filesystems, and that if you use only short
(8+3) filenames you are OK.
"Fatfs" is good freeware FAT code. Easy to implement and works, you just
need to provide functions to read and write blocks/sectors of raw data
from your media.

Microsoft have a number of patents, challenged, overturned, upheld and so
on. The issue is far from clear as far as I can tell.
If you can penetrate the legalese here,
http://www.microsoft.com/whdc/system/platform/firmware/fatgen.mspx, then
good job! From what I read, and IANAL, it looks like you can put products
together royalty-free that use this license as long as you correctly
implement FAT. This seems to *include* LFN support, should you wish it.
The IP portfolio pages that Microsoft had describing the $0.25 royalty
capped at $250K, IIRC, have disappeared. Perhaps they've decided that they
wouldn't be able to collect and FAT is ubiquitous anyway. Given the license
above, I think it is incompatible with the $0.25 royalty per device they
charged manufacturers.
I monitored the situation quite closely, but I am currently lost as to what
is possible with FAT and what it not.

Afaik you are not. But short of hiring a lawyer, trying to figure out
things for oneself would contaminate you. Software Patents are dicey
to say the least.

Re: ARM SBC - grantpbt - Aug 22 13:38:39 2008
I reduced my expectations somewhat and went with an IAR KickStart
board for the LPC2148. I didn't want the confusion added by external
memory for my first stab at this. I'm still stinging from some AMD
embedded x86 projects ;-)
http://www.lpctools.com/index.asp?PageAction=VIEWPROD&ProdID=82
So I got a character LCD, 2 UARTs, USB device, I2C, SD card slot and
RTC. I'll have to wait for the graphic LCD touchscreen for a while.
The Ethernet, USB host and Linux can wait until I've learned the
basics. Thanks for all the great recommendations. My WWW bookmarks
have expanded dramatically.

"Just the hardware, M'am". Anyway they don't make an ARM compiler and
it seems we have many to choose from as it is.

"Just the hardware, M'am". Anyway they don't make an ARM compiler and
it seems we have many to choose from as it is.

Use Google. There is source code out there for this.
The FAT file system is very old now. Even if there was a patent, it
would be expired now.

I've been happy with the MikroElektronica EasyARM board. The fact
they have an uncensored forum was a big 'plus' to me. Any comments
on their compilers are irrelevant to the quality of their LPC2xxx
ARM-based hardware products as they do not have an ARM compiler.
Apart from the wealth of features on such a low-priced board I was
most impressed by the number of simple code examples included - far
more than the usual 'Blinky' etc.
There was an issue for a while as the examples needed an older
version of the Keil ARM compiler which had to be downloaded
separately. This was resolved a few weeks ago so should no longer be
a problem.
