[commit] Werner Almesberger: Generate commit entry and show diffs also for the first commit. Plus cleanup. http://qi-hw.com/p/ben-wpan/56a9504
<wpwrak>
my superpowers have met their match: "You are not authorized to view this page." :)
<wpwrak>
to piece things together, maybe you can use those mysterious "grafts". jan luebbe would be the expert for these critters.
<wolfspraul>
try again
<wolfspraul>
I'm not even sure it's worth stitching the history back together
<wolfspraul>
it's just 4 days and quite a few commits are labeled 'just a kicad test' and similar
<wolfspraul>
if the mostly empty chie columns in the diffsch view would go away that's 95% of the value
<wpwrak>
yes, the sheets i see as "starting point" don't look overly exciting. most of the time, you only care about relatively recent things anyway.
<wpwrak>
now the access works
<wpwrak>
here's a quick cheat for the empty columns: just scroll to the right :) they're now all nicely bunched on the left side. the others are now populated.
<wolfspraul>
true
<wolfspraul>
it's very nice already, no doubt
<wpwrak>
still a few more things on the to do list ...i also want to get rid of the "commit" line and put the date there instead. small stuff.
<wpwrak>
i think they had a bit of an edit war at commits 9202afdec7dd4d8ea292fcd28611032cecc70dba 263badf95fc8844f891b1ab9d9d072bc05abf7dc and 16026245e7eb4ad70b623f25616fb27e278f71f1 :-)
<wpwrak>
i should make a new project with all those gadgets. there are also fpd2pdf and the new and improved dsv system. and then we have things like symbols and footprints that could also be shared.
<wolfspraul>
yes agreed, new project
<wpwrak>
i wonder if it should all go into one, or separate projects for scripts and symbols/footprints ? of course, the latter tend to have some small scripts as well, e.g., to turn fped footprints into kicad modules
<wpwrak>
ah, and then there's the question whether it's possible to migrate the git history along with the files
<wpwrak>
wolfspraul: "stripped". i think he means "gcc -s" or "strip some_executable" :)
<wpwrak>
dist.ro ... nice domain use :)
<wolfspraul>
I don't have overview over the scripts right now, their complexity, dependencies. so don't know about 1 project or multiple.
<wpwrak>
i would put the scripts into a single project. the question is whether this project should also host symbols and footprints or whether they should go elsewhere.
<wpwrak>
i.e., "one-stop-shopping eda stuff" vs. ("eda tools" plus "symbols/footprints")
<wpwrak>
the latter would be cleaner. the former would remove one step from the setup procedure. (you still need to get kicad, fped, etc. so the list of dependencies still has a certain size)
<wolfspraul>
with "symbols/footprints" you mean stuff shared between multiple kicad projects?
<wolfspraul>
then I would rather make 2 projects. you never know how things continue, who picks up what (also outside of qi).
<wpwrak>
(sym/fp) yes. e.g., xue and ben-wpan both reused stdpass.fpd from gta02-core (so there are now three copies of that file. hopefully all still identical ;-)
<wpwrak>
ok. soon we'll need a hierarchical project tree instead of a list ;-)
<wpwrak>
but first some food ...
<wolfspraul>
enjoy
<wpwrak>
thanks :)
<wpwrak>
cool. ftdi have a new series, the ft232r, where they now finally learned how to get rid of the crystal, too. in order to do more than basic serial conversion, e.g., to bit-bang, you need to use their binary-only library, though. no documentation to find about the protocol. do they never tire of that sort of shit ?
<kristianpaul>
dall i have one of those chips :/
<kristianpaul>
n/dall/damm
<kristianpaul>
two of then... :(
<wpwrak>
kristianpaul: so, really no free driver for the gpios ? i searched all their documents and came back empty-handed.
<kristianpaul>
seems there is for windows
<kristianpaul>
let me check again
<wpwrak>
silabs, on the other hand, have some usb-to-serial chips, where they provide a gpl'ed kernel driver for linux. so the protocol is implicitly documented :)
<kristianpaul>
ohh
<wpwrak>
what i'm after is a usb-to-a-bunch-of-gpios chip that doesn't need any firmware bootstrap, so that i can use it for a firmware bootstrap programmer for the c8051f32x.
<kristianpaul>
well i need sorft of that i think too for some coming boards too
<kristianpaul>
but with high speed bit bang (3Mhz)
<kristianpaul>
to usb
<wpwrak>
there are some larger ftdis that can do this and where the protocol is documented
<kristianpaul>
buit i think you can setup bit bang/gpio on the EEPROM just the provided sofware is avalaiable for windows only it seems
<kristianpaul>
i'm reading DS_FT232R.pdf page 13
<wpwrak>
silabs' c2102 goes up to 1 mbps. i think it's just a c8051f327
<wpwrak>
oh, that doesn't look too bad. i see sources :)
<kristianpaul>
compile, compile !
<kristianpaul>
i guess blobed sources..
<wpwrak>
ah no. that's just libusb
<kristianpaul>
shit
<kristianpaul>
oops
<wpwrak>
libftdi, however, seems to support he ft232r
<wpwrak>
okay, that's acceptable. phew. why make it easy if you can let people jump through hoops :-(
<kristianpaul>
i did :'(
<kristianpaul>
was cheap i i bought in a colombia electronic shop to avoid import more stuff
<kristianpaul>
s/colombia/colombian
<wpwrak>
yeah, they're very widespread. that's why i was considering it in the first place. the goal here is to make something that's easy to get.
<wpwrak>
hmm. small obstacle. i need to be able to create a pulse of 20...5000 ns
<kristianpaul>
thats not so small i think ;)
<wpwrak>
5 us is plenty of time in most cases. however, if you're on the other side of USB ...
<wpwrak>
but it seems that the ftdi can bundle multiple operations in a single usb transfer
<wpwrak>
one more item for my digi-key shopping list :)
<kristianpaul>
:)
<kristianpaul>
any one had take a look to the wikiriader summer update?
<wpwrak>
grmbl. x complains that i'm at the maximum number of clients :-( nonsense. only 316 in total.
<wolfspraul>
symlinks, X clients, ...
<wolfspraul>
kristianpaul: they keep hacking, but it's very tied to their own microkernel and embedded system. will be hard to reuse for anyone else.
<wolfspraul>
but of course it's good, if they continue and have a clean design maybe some things are reusable...don't know. I would probably start with those textual readers we found recently, and once I run into issues the wikireader project would be one to look for sources to cut & paste from.
<kristianpaul>
rafa__:Â Â did a great work about that
<kristianpaul>
at least is simple and works
<kristianpaul>
but getting the dump not sure how hard or update it is?..
<wolfspraul>
what reader did rafa__ work on? and what dump format does it need? I didn't follow in detail...
<kristianpaul>
is a dump from the humane project
<kristianpaul>
i think is not up to date
<kristianpaul>
arggg damm my processor is getting slow :/
<kristianpaul>
nv
<kristianpaul>
now i see whye two cores are important :)
<kristianpaul>
i think the script from humane have problems with the lastest wikipedia dumps
<kristianpaul>
so the guy from the porject sent and old already done dump wich already works
<wpwrak>
so all the cheap wifi antennas don't fit directly on a "standard" sma system. instead, they need some sort of adapter.
<wpwrak>
hmm, does anyone know if there's a reasonable way to move a file, along with its revision history, from one repository to another ? let's assume for simplicity that all the commits changing that file changed only that file.
<larsc>
hm
<larsc>
quick and dirty: cherry pick each commit that changes the file
<wpwrak>
larsc: hmm, but that doens't work across repositories. i could of course convert commits into patches, and apply these. hmm ...
<larsc>
well you can add the one as a remote to the other, cant you?
<wpwrak>
ah, that may be an option indeed. haven't used that yet.
<wpwrak>
yeah, i like the idea. thanks a lot !
<wpwrak>
and an EE question: i'm looking for a simple small shielded connector that plugs and unplugs easily. should interface well with rg-174. the usual barrel types are cheap but they're all on the large side. the best choices seem to be mcx and mmcx. which of these two is more future-proof ?
<he2>
hi
<he2>
has some one tried to install debian on the nn yet?
<wpwrak>
hmm, mmcx seems to be the choice. has nice board edge connectors.
<wolfspraul>
wpwrak: OK I understood the sma/rp-sma problem now. oh well. Wikipedia says it's to make it harder to connect antennas that would create a system the FCC doesn't like.
<wolfspraul>
I'll go read that section mentioned in the Wikipedia article now :-) (15.203 Antenna requirement)
<kristianpaul>
wolfspraul: that could be a problem with GPS Atenna too, at least about finding a small one sma-like compatible
<kristianpaul>
the GPS's i saw in the past have build in atenna i think
<wolfspraul>
or rather 'a hacker has to be really good' regulation
<wolfspraul>
interesting
<kristianpaul>
", but the use of a standard antenna jack or electrical connector is prohibited" !!!
<kristianpaul>
but thats stupid i saw phones with sma-looking connectors
<wolfspraul>
yes, that's where (if I understand things correctly) Werner's problem of finding a standard antenna comes from
<kristianpaul>
is the same thinfg i can attach other atenna anyway
<kristianpaul>
yes it seems
<kristianpaul>
thats just make all this propietary now each vendors have their own stuff to sell at high rates !
<wolfspraul>
I am wondering whether a device that has a standard connector behind plastic, but where you first need to drill a hole, would be considered sufficient.
<kristianpaul>
like the weird TNC connector in some Linksys wireless
<wolfspraul>
if we ever ran into this, we would need to find out what's 'hard enough' so it passes the FCC approved hacker standard
<kristianpaul>
may be easy attached/detach atenna with haker-like connector (of course not standard)
<kristianpaul>
damm i saw it before but i tought it was gps too
<wolfspraul>
wpwrak: have you solved the antenna problem you had? anything I can do to help?
<wpwrak>
wolfspraul: no need to add fcc-displeasing connectors. probably within the hours after they passed that regulation, the factories started producing adapters rp-sma to whatever you fancy ;-)
<wpwrak>
kristianpaul: (antenna) cute :)
<kristianpaul>
heh seems the GPS antenna was no big deal after allm whe you eliminate wthe word SMA from the search ;)
<kristianpaul>
wpwrak: why not atenna in PCB
<kristianpaul>
i saw mesh potatoe using
<kristianpaul>
that idea
<wpwrak>
kristianpaul: it's for the test equipment
<kristianpaul>
ah
<kristianpaul>
i toght was real solution
<kristianpaul>
tought*
<wpwrak>
my next order at digi-key will have a bunch of sma/mmcx/u.fl parts in it :)
<kristianpaul>
:)
<kristianpaul>
they should give you discount if you keep buying all that things ;)
<wpwrak>
it's a pity you need to many different sizes. bnc for scopes and the like, sma for rf, mmcx if it should be coax and resonably small (e.g., for my frequency counter), and then u.fl if it should go on the board.
<kristianpaul>
ouch
<wpwrak>
(discount) they found a good fede rate for argentina. down from usd 100+ to usd 40. that's already quite nice :)
<wpwrak>
fedeX
<kristianpaul>
where i can ceck rates to colombia btw?
<wpwrak>
i'll make the frequency counter a usb dongle. should be fun :)
<kristianpaul>
i need to move from sparkfun to a more serious provider
<wpwrak>
whee. usd 100 for you. that's because the plane has to stop so soon :)
<kristianpaul>
is just sparkfun shiping is cheap as i can choose from first class to next two fays deliver :)
<kristianpaul>
damm
<wpwrak>
digi-key are extremely well organized. and they're incredibly fast. you send them a 100+ items order before 7 pm their time and it's on the plane that same night.
<kristianpaul>
may be i can send it to miami then to colombia
<kristianpaul>
wow
<wpwrak>
ah, you can try usps. digi-key sometimes offer that, too. that may be cheaper.
<kristianpaul>
ok
<kristianpaul>
what some cuntries have 100+ free shipping??
<wpwrak>
andres-calderon: i saw that you have an A2 sheet among your schematics (for the FPGA). is this really pleasant to work with ?
<wpwrak>
wolfspraul, andres-calderon: btw, schematics are now properly scaled. i seem to have a number of false changes on the fpga sheet, though. still debugging that one. http://www.almesberger.net/misc/ben/demo2/
<andres-calderon>
not really, but the FPGA is composed of five big parts...  I do not know how to handle in differently way.
<wpwrak>
andres-calderon: just put them on different sheets ?
<wpwrak>
the big sheet must be difficult to read if you print it on A4. it also looks ugly in my bitmap images, that's why i care :)
<wolfspraul>
maybe the scale (pixel resolution) of the large image could be a bit larger still? I think some text is hard to read, especially when green and red are written over each other.
<wpwrak>
i could make it larger, yes. but then that becomes difficult to naviate ...
<wpwrak>
what i'm thinking of is to also generate pdfs (zoomable but without deltas). that way, one could go there for the details.
<andres-calderon>
wpwrak I do not know if a component can be split  through multiples sheets.
<wpwrak>
the workflow would then be to first pick an interesting change from the overview, have a look at the detail picture, and then go to the pdfs to see every last detail.
<wpwrak>
green and red overlays are virtually impossible to make readable.  i would have to make an animated gif or such.
<wpwrak>
of course, with pdf you could just flip back and forth. so that solves the problem as well. particularly if you know where to look.
