<kristianpaul>
theorically and legally what is the maximun coverga i can achieve under the 802.15.4?..
<kristianpaul>
acording to wikipedia the PHY "902-928 MHz: North America"
<kristianpaul>
so that should improve coverage a bit i think
<kristianpaul>
hmm IEEE 802.15.4c
<rjeffries__>
kristianpaul assume you know the radio in ATben ATusb is 2.6Ghz
<rjeffries__>
i mean 2.4 Ghz
<kristianpaul>
sure
<rjeffries__>
I need to read data sheet for the RF chip
<wpwrak>
rjeffries__: you're correct. the chip only does 2.4 GHz. IEEE have specified a fairly large number of PHYs for 802.15.4, some in 802.15.4-2003 and -2006, some in 802.15.4a, etc.
<rjeffries__>
wpwrak if there wre a next Nanonote, you see ATben as ain internal plugin, I suspect?
<wpwrak>
rjeffries__: as a fixed internal subsystem
<rjeffries__>
relayed" why to just build the AR86RF231 and antenna etc on main pcn
<rjeffries__>
so the second 8:10 would be for... memory card
<rjeffries__>
i think i understand
<rjeffries__>
yupos be damned
<rjeffries__>
typos
<wpwrak>
rjeffries__: ideally, two 8:10 for whatever use. the internal one typically with a memory card, the external one possibly with UBB and friends. the internal one should be placed such that peripherals would protrude into the battery space, so that one has the option of mounting something larger, even if only temporarily
<rjeffries__>
would you like to get rid of NAND
<wpwrak>
yeah :)
<wpwrak>
i don't like nand. it's messy and doesn't age well.
<rjeffries__>
nods
<kristianpaul>
ergg, nand uses a parallel data bus,
<kristianpaul>
well NOR?
<rjeffries__>
do 16 GB mem cards work with Ben now?
<kristianpaul>
you got a 16Gb mem card and is not working?
<wpwrak>
kristianpaul: NOR is like RAM. NAND typically uses a narrower bus. in the ben: DRAM 16 bits, NAND 8 bits, 8:10 4 bits
<rjeffries__>
no I am asking wonder also if 3GB is ok
<wpwrak>
kristianpaul: NOR is also expensive, compared to NAND
<rjeffries__>
32 GB
<wpwrak>
kristianpaul: for the ya, i'd want DRAM on a 32 bit bus. and DDR/DDR2.
<kristianpaul>
no non-volatille memory?
<kristianpaul>
ah, like in the early palms ;-)
<kristianpaul>
i had a m101 stored somwhere, that really booted fast
<kristianpaul>
oh sure 32 birs is way to go :-)
<kristianpaul>
bitS
<rjeffries__>
I have a Palm Treo that is still running (although I am not actively using iy)
<rjeffries__>
when teh phone radio is not active, battery life is amazing
<rjeffries__>
I did not keep track, but it has run several weeks now, I'd say will over a month
<kristianpaul>
anyway, my point was recall fast boot by use of a flash memory with a wide bus, or may be a hibernate/resume/suspend technique, wich btw the nanonote  is capable of suspend at least..
<kristianpaul>
palm m100, sorry
<kristianpaul>
nice times :-)
<wpwrak>
larsc: btw, how many MMC controllers does the 4760 really have ? the programming manual seems somewhat undecided between 2 (section 35) and 3 (sections 1 and 41)
<larsc>
wpwrak: although the devboard has only two mmc card slots
<larsc>
but since it is possible to map all 3 mmc cores to port E I should be able to test them all
<wpwrak>
larsc: ah yes, all neatly together
<kristianpaul>
hehe, i got all mimi and eunice cartoons with wget --mirror :D
<kristianpaul>
38M..
<kristianpaul>
well i can delete 640x199 vesion..
<rjeffries>
This looks like a good book on "Internet of Things" which I claim (humble as always) may be a solid target market for a future Nanonote with integrated 802.15.4 6LoWpan radio
<wpwrak>
rjeffries: how do you imagine it to be a target market ?
<LunaVorax_mini>
I was skeptical about the accuracy of this book  rjeffries... and then I saw that one of the author is a member of the Contiki OS. That's enough to convince me that the book isn't bullcrap
<rjeffries>
wpwrak Ben could be a verty low cost potable terminal that talks to a collection of 6LoWpan devices
<rjeffries>
a while ago I talked with an engineering grad student at CalPoly a local college
<rjeffries>
he is working on a project where they use wireless at a station to exchange batteries for electric vehicles
<LunaVorax_mini>
Talking about the Ben. I know I'm annoying with that but every day I tell myself that if the Ben had a video out + ethernet (or easy network/internet connection) + usb host, appications of this devices would be endless... sounds stupid but it definitely is true
<rjeffries>
when I say Ben I really mean a followon that has the radio built-in
<rjeffries>
LunaVorax_mini I agree. wpwrak dislikes ethernet due to size of rj45 connector but it is a univaersal way to hook up to a router
<rjeffries>
my thinking is that soem small compromises on formfactor to allow
<rjeffries>
a bit more space while not going anywhere close to netbook size would work
<rjeffries>
the idea of a nanonote (future) that supports a better keyboard that is also a little
<rjeffries>
larger makes sense. the usability of current keyboard is IMO poor (and I am being polite)
<rjeffries>
that book is expensive $58 USD but I may buy it to learn more
<LunaVorax_mini>
I believe the Ben should be forked into a Milkymist-like device. A board for a lot of uses.
<LunaVorax_mini>
I though about simple jukeboxes playing musing from local network or "retro" video game consoles
<rjeffries>
LunaVox_mini that is what I am thinking. iT DOES NOT HAVE TO BE A CONSUMER ELECTRONICS DEVICE TO FIND A MARKET
<LunaVorax_mini>
Wow
<LunaVorax_mini>
Caps lock troubles ?
<rjeffries>
sorry for all caps mistake. d'oh
<LunaVorax_mini>
hahaha
<rjeffries>
yup
<LunaVorax_mini>
At least I got it right
<LunaVorax_mini>
I wasn't thinking in a "find a market" way
<LunaVorax_mini>
Only in a "hack it" way
<LunaVorax_mini>
The Ben is hardly hackable, unless you go into the schematics and build your own, right ?
<LunaVorax_mini>
I feel bad for giving my opinion but not having the required knowledge to give a real hand.
<rjeffries>
the board Carlos started (SIE, earlier called swiss army knife card) that married Ben SOC with an on-board FPGA and dumped the keybaord, but allowed for Ben LCD display and had USB host and Ethernet is close to what we could envision, but implmented with new Ingeninc SOC 4760 one assumes
<LunaVorax_mini>
Hum
<rjeffries>
oh and with werner's radio stuff naturally
<LunaVorax_mini>
What is this ?
<LunaVorax_mini>
Radio ?
<LunaVorax_mini>
Like FM Radio ?
<rjeffries>
ATben ATUSB 802.15.4 which has reach of 10 meters or more, about 1 Megabit per secone, 6LoWpan protocol
<LunaVorax_mini>
Ok
<LunaVorax_mini>
I'm not really sure I know what this protocol is
<LunaVorax_mini>
Oh right ipv6
<LunaVorax_mini>
Man I still live in 1989
<LunaVorax_mini>
I forgot ipv4 ended
<LunaVorax_mini>
I mean
<LunaVorax_mini>
Well you understood
<wpwrak>
rjeffries: (ben as wpan console) sure, it can do that. but is plain 6lowpan enough ? or are there more stacks that need supporting ? i.e., what exactly do the things you envision it to talk to talk ?
<wpwrak>
rjeffries: (ether) i think it's slowly dying. i'm a luddite myself, but i see less and less reason for putting up with wires. and outside the near confines of my lair, it's a wifi world anyway
<wpwrak>
LunaVorax_mini: (video out) i wonder if you couldn't bitbang, say, CGA ;)
<wpwrak>
hmm, would be nice to have something like this for ben+ubb: http://ucontroller.com/Propeller Protoboard Designs for the Beginner.pdf
