2011-03-29 00:03 latest milkymist gui screenshot: http://www.milkymist.org/flickernoise/darkblue.png 2011-03-29 00:06 very nice ! 2011-03-29 02:38 that milkymist screen shot is ultra cool 2011-03-29 12:19 autocrap travesty of the day: seems that they discovered "quiet" builds. of course, unlike everyone else who adds a means to enable verbosity (V=1 or such), they had to hard-code the quietness in the makefile. as if a build under the auspices of autocrap could possibly ever fail ... 2011-03-29 12:20 :D :D :D 2011-03-29 12:20 I usually patch the quiet patch out 2011-03-29 12:20 erm quiet stuff 2011-03-29 12:26 i like it for making warnings and such more visible. but there has to be a quick way to see the whole truth when debugging ... 2011-03-29 13:01 [commit] Werner Almesberger: install/: kernel and system utilities build instructions (preliminary) http://qi-hw.com/p/ben-wpan/fb5bb5a 2011-03-29 13:01 [commit] Werner Almesberger: atben/README-PCB, atusb/README-PCB: clarifications regarding holes http://qi-hw.com/p/ben-wpan/6487c32 2011-03-29 13:01 [commit] Werner Almesberger: install/: updated and corrected build instructions http://qi-hw.com/p/ben-wpan/16dcc30 2011-03-29 13:28 tuxbrain: yesterday, we heard about russian postal snails. how are the spanish smt snails doing ? :) 2011-03-29 13:54 wpwrak: the snails said this afternoon they will make a "sprint" and send the quote.... I want a world with the efficiency of germany, patience of Japanese , Chinese production, Hindu spirituality, Netherlands legislation sense, EEUU entrepreneur spirit, Spanish  improvisation skill and (ok some French cheese ,bread and pastry can pass the filter too)  , Russian maths toughness,  Nordic mythology and metal, Swiss economical skills... (add/remove you 2011-03-29 13:54 own receipt to the ideal world)... until then let's wait the spanish efficiency with EEUU patience :P 2011-03-29 13:56 heh, let's hope for the best then :) 2011-03-29 16:50 and the snails have made the sprint :) 2011-03-29 16:52 :O 2011-03-29 17:01 wpwrak: I have send you a email with the quoting , no info about the usb connector apart of the warning on the paneling , I have requested for the ref/vendor and/or datasheet of it. 2011-03-29 17:25 tuxbrain: "Pantalla Serigrafia Niquel" is the stencil ? 2011-03-29 17:28 tuxbrain: prices look so-so to me. not excessive, but i also don't know if they couldn't be substantially lower. maybe ask adam for his opinion. 2011-03-29 17:34 tuxbrain: (usb conn) great. 2011-03-29 17:34 tuxbrain: i'll be afk for a few hours. let's see of more data arrives :) 2011-03-29 18:49 he, a C structure is very cool :-) 2011-03-29 18:49 usefull 2011-03-29 18:49 reading about tcp/ip 2011-03-29 19:19 kristianpaul, C structure allows OO in C 2011-03-29 19:22 but you should pass structure pointer to object functions directly then :) 2011-03-29 19:22 is using some kind of such things.. 2011-03-29 19:22 has anyone managed to get qt running on ben? 2011-03-29 19:23 fb->plot_pixel(fb, x, y, color); 2011-03-29 19:24 per my experience, 32mb is too little for it, but maybe i'm compiling qt the wrong way 2011-03-29 19:26 methril_work: he, i was thiking same actually 2011-03-29 19:26 whitequark: it is 2011-03-29 19:26 check nanomap for example 2011-03-29 19:26 and others games i think 2011-03-29 19:26 qdict too 2011-03-29 19:26 kristianpaul, it`s used like that in kernel VFS 2011-03-29 19:27 i did some serialization of "objects" -> C structs 2011-03-29 19:28 and sent over the net 2011-03-29 19:28 it works nice :) 2011-03-29 19:31 "object functions" :o 2011-03-29 19:36 methril: in VFs and a gazillion other places :) 2011-03-29 19:46 tuxbrain: regarding the component substitutions: the 1 uF can is in fact the one i specified. the others are okay as well. 2011-03-29 19:56 nods wpwrak words 2011-03-29 20:41 http://www.milkymist.org/flickernoise/pdf.png 2011-03-29 20:47 lekernel: that's your upcoming book ? :) 2011-03-29 21:01 whitequark: you have to be some restrictive (example I'm getting problems if I use large fonts) but with starndard ones I was able to compile on pc and run some demos on NN and I'm developing a code editor app for arduino on QT creator 2011-03-29 21:01 yeah 2011-03-29 21:03 gn8 dudes, today I'm tired and need to rest. and there is no caffeine arround to make me change of opinion. c u 2011-03-29 22:58 so, what graphical environment may be used on ben? I've tried gmenu2x, and it works perfectly (of course), but is not very feature-rich and the code is somewhat crappy 2011-03-29 22:59 http://projects.qi-hardware.com/index.php/p/mmone-jtag-serial-cable/ You are not authorized to view this page. 2011-03-29 22:59 mhh 2011-03-29 23:00 wpwrak: since I can't take a look at the mmone-jtag, can you tell me how to add a SMD mini usb jack with KiCad? 2011-03-29 23:00 is there some special library I need? 2011-03-29 23:00 whitequark: jlime is using kdrive+matchbox iirc 2011-03-29 23:01 or may be xorg+matchbox 2011-03-29 23:34 Jay7: looking at their screenshots, matchbox requires touchscreen, am I right? 2011-03-29 23:35 whitequark: no, jlime's one is driven by keyboard 2011-03-29 23:36 hmm, that's not very easy when you have maybe 8 keys 2011-03-29 23:36 nanonote have lot of keys :) 2011-03-29 23:38 the particular thing I'm searching an environment for has much less, but otherwise has very similar hardware 2011-03-29 23:38 well, of course I may attach a keyboard on i2c, but I do not want to do that 2011-03-29 23:39 minimal keys requirement is 2 :) 2011-03-29 23:39 down and select :) 2011-03-29 23:39 better with 3 - up/down/select :) 2011-03-29 23:40 you should be happy with 5 :) 2011-03-29 23:40 hm. 2011-03-29 23:40 are you looking for a toolkit, menu, desktop? 2011-03-29 23:40 ah, yes, some key for closing window and changing between 2011-03-29 23:40 one modified should be enough :) 2011-03-29 23:41 *modifier 2011-03-29 23:42 mth: if I've had 64mb of memory, I'd just use qt for everything and be happy. I'm looking for everything I need to build an usable media player on top of Linux, of course FOSS 2011-03-29 23:42 but qt is too fat to run simultaneously with mplayer, and gtk is not something I'm happy with, too 2011-03-29 23:42 whitequark: opie? :) 2011-03-29 23:43 qtopia is dead 2011-03-29 23:43 but still working :) 2011-03-29 23:44 for an one-time project it would work (iirc it has used only ~7mb of memory by itself, through on arm), but I'd like to make something which may be reused 2011-03-29 23:44 whitequark: DirectFB is pretty light and was designed for use on set-top boxes 2011-03-29 23:44 you can run wxWidgets on top of it if you need a widget toolkit 2011-03-29 23:44 hm, wxwidgets 2011-03-29 23:44 i'll look into that, thanks 2011-03-29 23:45 Jay7: opie.handhelds.org is down too 2011-03-29 23:45 wxWidgets is highly modular, so you can disable widgets you don't need 2011-03-29 23:45 whitequark: opie.sf.net 2011-03-29 23:45 opie is moved from hh.org long time ago 2011-03-29 23:45 although I ran into compile errors when I did that, but they weren't hard to fix 2011-03-29 23:45 and all my patches from back then were integrated by the maintainers 2011-03-29 23:47 mth: looking at their screenshots, they use some underlying graphics library, win32 or gtk 2011-03-29 23:48 it can do that, but it can also use its own widgets on a low-level gfx lib like DirectFB 2011-03-29 23:48 we had a user interface for an embedded system running on it 2011-03-29 23:48 oh yes, I see it. looks like we're back in '95 2011-03-29 23:48 DirectFB + wxWidgets had a much smaller flash footprint than kdrive + wxWidgets 2011-03-29 23:49 wxwidgets is shit. dont use it. 2011-03-29 23:49 we did implement a custom theme to make it look good 2011-03-29 23:49 mth: do you have a repo of that? 2011-03-29 23:49 no, it was a proprietary app 2011-03-29 23:49 make stuff look ugly and breaks thing which worked before on all platforms 2011-03-29 23:50 which was also the reason we didn't use Qt 2011-03-29 23:50 they didn't want GPL licensing and the per-unit cost of Qt was also too high 2011-03-29 23:50 this was before Qt was LGPL-ed 2011-03-29 23:50 roh: any suggestions on your side? 2011-03-29 23:51 if you have enough resources, go for Qt instead of wxWidgets 2011-03-29 23:51 well.. directfb alone isnt a toolkit. its like gdk 2011-03-29 23:51 but in this particular restricted environment wxWidgets worked well for us 2011-03-29 23:51 mth: 32mb and a processor roughly like ben's 2011-03-29 23:51 its for drawing and windowing, but for a actual toolkit you need something more. usually people use wither gtk or something completely different. 2011-03-29 23:52 there is some very simple stuff.. i forgot the name. mompls 2011-03-29 23:52 roh: gtk looks nice and has not very big footprint, but its c interface makes me cry 2011-03-29 23:52 'lite' 2011-03-29 23:52 there was a framebuffer port of gtk, but it was unclear to me whether it was maintained 2011-03-29 23:52 whitequark: you can still code in different languages.. vala? 2011-03-29 23:53 and compile down to binary. 2011-03-29 23:53 c++ is nearly always much bigger in binary and memory footprint size 2011-03-29 23:53 http://directfb.org/index.php?path=Platform%2FLiTE 2011-03-29 23:53 mth: gtk on dfb is what debian used afaik for the installer. 2011-03-29 23:54 I've always installed Debian with a text mode installer :) 2011-03-29 23:54 dfb can also run on dumb framebuffers. its 'abstracting' the hw of the fbdev so you can use accel if available. 2011-03-29 23:54 roh: back when I've looked at it, it was looking like in very early stage, is it stable now? 2011-03-29 23:55 roh: yes, deb's graphical installer uses dfb. I'm thinking about implementing some graphical acceleration with DMA, through I don't know how efficient that would be 2011-03-29 23:55 lite? dunno. i havent worked with that stuff for years. but i know that directfb is still maintained and used in real products.. tv's and such 2011-03-29 23:56 roh: no, vala 2011-03-29 23:56 whitequark: dfb does abstract that for you (accel) 2011-03-29 23:56 roh: sure, but it would fall back to slow way like naive memcpy 2011-03-29 23:56 instead of e.g. a userspace x11 driver one has a userspace dfb driver and (usually) a kernel component (the fbdev) which allows mapping/access to registers and dies modesetting. 2011-03-29 23:57 well I use jz4740-fb just in NN 2011-03-29 23:57 so accel is usually in userspace, and modesetting in kernelspace. sometimes even simple blitting (for scrolling) 2011-03-29 23:58 I particularily like some features of dma like striding and descriptors, it may be possible to implement acceleration for simple ops (like blt) with these 2011-03-29 23:59 nah. usually not 2011-03-29 23:59 with 320x240 resolution, often software rendering is fast enough
