A couple of readers have submitted links to gumstix, a homebrew microcontroller
based on the Intel PXA255
XScale CPU. The board is 20mm x 80mm, has 64MB SDRAM, 4MB of Flash,
draws 200ma at 3.6-5v and runs Linux. At present, the site only has a
brief description and a photo but it sounds like the creator may be
releasing the design as Open Hardware soon. Slashdot also carried a
on the gumstix board today.
Im freakin' impressed with what I saw, the gumstix microcontroller is
excellent....4Megs of flash mem, and 64 Megs of Ram....thats awesome,
we could frag bots and play quake-3 on that tiny lil thing..;).
The PXA255 processor is based on the older .18u technology....I
speculate they will be launching the 0.13u silicon soon, as the
mainstream processors will all be manufactured on the .09u. If
manufactured using a 0.13 micron silicon die, the PXA255 will be
drawing around 160mA, may work on something like 2.8volts, thats all
the more impressive. Im pretty impressed with the Transmeta Crusoe,
tailored for ppl who are going to work on Hard-core voice recognition,
and other high end applications, though the Crusoe kit is a bit
expensive at 900 odd Dollars.....
The real trick is how you would get a program to compile for it.
If it uses a GnuCC compiler. What are the actual command lines and
options needed to compile a program for it? RTFM is fine and dandy but
it doesn;t really mean all that much.
Or do you spend $12,000 US for a Codewarrior IDE and compiler?
If they have a embedded Linux, do you use Python or Perl instead
Unfortunately, its too small and light to make a decent paper weight.
