Would this project plan be ok:
software and hw: Karl
testing and spec's: Folderol
publication via web: anyone??
git repo: git://aspodata.se/openhw.git
mailing list: hopefully this list, else I put one up at my site
web site: ??
intial platforms (both by Atmel):
. ATNGW100 (cheap), and
. AT91SAM9260-EK (expensive)
Next step:
. set up development platform
. simple test with spi and shift registers
Regards,
/Karl
