Nice, documented very well too, take note of the errata though. Anyone
know why the analog only device takes more power then the digital? I
can't figure that out.

Nice. http://www.xiltendo.com I wonder why I bought the expensive original
Xilinx platform cable :-)

Yes, the concept is the same for many game consoles. Some time ago I've
started the Lua Player project for the PSP and the security for the very
first PSPs was nearly no security at all, which made it easy to just copy
the programs to the memory stick with the integrated USB port from a PC.

You are right, I think there is no cheaper development kit for this price
with audio IO, two color screens, where one is a touch screen, USB, WLAN,
two CPUs, integrated rechargeable battery etc. Maybe I'll try to do some
stuff for it when I have more time. Too bad that Nintendo locked it, so you
have to hack it.

Oh, the 331 I know about that one, it's 250uA in normal mode. no real
power saving there, I was hoping you were referring to a newer model

Hi Frannk
the SPI interface is done with this board
http://www.microdream-1.com/CPLDStarter.html
the CPLD is inslot programmable using DS version of Xilinx XSVF
player :)
hum.. you seem to be well informed? There are 5 DS roms known that
have
know STACK overflow exploits found that allows the game state eeprom
to be written with special code that is executed after being loaded.
but those are not old games :) you cant just go and buy any old game
it is of no use! For making the slot2 adapters, then well 1.6mm thick
PCB is all you need
I find the DS the easiest gadget to use, the CPLD board is SO
easy to use and reprogram - no need to fight with impact :)
and the C library support is superiour, really easy to write
hardware related stuff.
much more easier than it was in the old days when PCs
used to have LPT ports!

I like the idea using a Nintendo DS for implementing a SPI test hardware.
Is there any simpler method of hacking this console than buying an old
cartdrige and overwriting the EEPROM?

The new Analog devices ADXL345 is somewhat similar (25uA instead of
10uA and bigger), the low power is achieved only at very low sample
rates.
I can't find the ST version, do you have a link?
thanks

i uploaded a picture of working prototype with cma3000
http://groups.google.com/group/antti-brain/files?hl=3Den
this is shot of very first test, the c program overwrites screen
without clearing background so the numbers look bad

we are going to supply adapter PCBs soon
probably before the ICs become available :)
the BGA8 is actually not hard to solder to correctly designed land
if you read our NOV issue there is a picture of CMA3000 soldered
to simple break out board
funnily, not only Digikey has LEAKED the NDA only datasheets
but also one russian company
http://airborn.ru/news/accelerometer_cma3000/
they even have some example C code examples online :)
