qi-bot[commit] Adam Wang: pwr.lib: fixed pin name (master) http://qi-hw.com/p/kicad-libs/514047602:44
qi-bot[commit] Adam Wang: js28f256j3f105.lib: removed duplicated pin22 (master) http://qi-hw.com/p/kicad-libs/f0ec97a03:02
cladamw(KiCad BZR 3494) it CANT detect an err about duplicated pin when ERC. It's bad. (i.e. I cant reply on the ERC in eeschema) Must do ERC in Library Editor prior to schematic editor.03:07
wpwrakyeah, i think it only detects duplicate pins in schematics if they cause some other problem. e.g., if two outputs drive the same net03:10
cladamwyeah. eeschema could detect some wrong while verifying electrical types, but i was amazing that it cant detect that Pin22's in flash chip even we got 0 err before. so i just finished all board-m1's symbols checked by "Test for duplicate and off grid pins". man!03:17
cladamwwpwrak, i just summaried some contents of your mails for http://en.qi-hardware.com/wiki/Rules_on_Editing_Schematics03:19
cladamwsome sub-tiltle names may be not good. few are I've not filled in. If you have new idea once, lemme know then we put idea in there.03:20
cladamwneed more worse/bad, better/good pictures to show each rules. i'll keep working on this while i make sch better, the gta-02 pdf link is a nice example though. thanks.03:22

qi-bot[commit] Maarten ter Huurne: fbcon: Add 6x10 font (jz-3.3) http://qi-hw.com/p/qi-kernel/b13e7eb14:50
qi-bot[commit] Werner Almesberger: components/EXPAND: trace AVR-M1005C080MTACB to VARISTOR name change (master) http://qi-hw.com/p/kicad-libs/541e54315:11
qi-bot[commit] Maarten ter Huurne: fbcon: Tweaked menuconfig help for 6x10 font (jz-3.3) http://qi-hw.com/p/qi-kernel/aa23d3a15:33
qi-bot[commit] Maarten ter Huurne: MIPS: A320: defconfig: Switch to 6x10 font (jz-3.3) http://qi-hw.com/p/qi-kernel/6f86cc915:33
Aylamaybe Nanonote users want it too15:34
mththe NanoNote font uses special colored glyphs to get the best result on the alternating subpixel positions on its screen, afaik15:46
mthnot sure if a generic font can beat that15:46
qi-bot[commit] Paul Cercueil: Read the credits from the "about.txt" file. (master) http://qi-hw.com/p/gmenu2x/c2576d415:58
qi-bot[commit] Paul Cercueil: dingux: added a link to disable the graphic mode of the framebuffer (master) http://qi-hw.com/p/gmenu2x/45595e215:58
kyakmth: not using it by default anymore due to a popular request16:06
kyakdefault is 6x1116:06
kyakwhich i would really like to replace with terminus by default16:06
Aylaah, then you should switch to 6x10 too16:08
kyakthe font you talking about is greta, but has no colors.. so we provide a special shortcut for that16:08
kyakin gmenu16:08
Aylayou can write in color, using escape codes16:08
kyaknope16:09
kyakit just doesn,t have colors.. 16:09
kyakas mth said, it IS colored16:09
Aylawhat is the value of $TERM ?16:09
kyakbut special placement of ben,s pixels makes it look like it,s not colored16:10
kyakyou dont, quite understand, sorry :)16:10
Aylano I don't16:10
kyakthere is an article in qi wiki , search for setfont216:10
kyaki cant,t give you the link right now16:11
kyakwe can dispaly colors, but with other fonts16:11
kyakliks 6x11 or terminus or any other16:11
kyakjust not that special font from setfont216:12
kyakirrelevant of TERM env var16:12
Aylaif TERM=vt100 you won't have color at all16:13
kyakdid you read the article?16:14
AylaI'm looking for it :)16:14
kyakit,s linux btw, but again, it doesn,t matter16:14
mthkyak: if you're using 6x11 now, then the 6x10 font I just committed is probably an improvement16:14
mth3 more lines and more distinct characters16:15
kyakthat,s for sure16:15
kyakdoes it have ascii onky?16:15
kyakonly16:15
mthit's forked off the 6x11 font, same chars16:15
kyakah ok16:16
kyakyou should make it global then, ben users won,t mind :)16:16
mththe 6x11 font had a very large line spacing, so it was easy to remove one line from each char16:16
mthit's in the qi-kernel git; I don't know how to get it from there to NN users16:17
kyakwe have this font in userspace, it,s loaded by startup scrapts16:18
kyaki guess we just don,t load it and then we will get 6x1116:18
kyak6x10 sorry16:19
kyakonce we catch up with qi-kernel git, of course16:23
kyakmth: did you try that terminus font to see how it looks?16:23
mthno, but I don't have a NanoNote and the Dingoo has an ordinary LCD panel16:24
kyakif not, you should try; it,s really a nice looking font16:24
kyakeven better16:24
kyakit,s not nanonote specific16:24
mthah, terminus is not the colored font?16:25
kyaknope, it,s a regular font16:25
kyakbut has more glyphs16:25
kyaki use it by default on my laptop as well16:26
kyakvery popular in a cyrillic world16:26
mthit looks rather similar to the 6x11 font though16:28
kyakwell, it looks much better.. but all fonts are similar anyway )16:28
mththis is the 6x10 font: http://www.treewalker.org/temp/font_6x10.png16:29
kyakindeed very nice and has more than ascii glyphs16:31
mthit's the IBM PC character set, I think16:31
kyaki,ll try it on ben,s screen as soon as i can16:31
mthif you want to change character, here are the tools: http://www.treewalker.org/temp/font2png.py http://www.treewalker.org/temp/png2font.py16:32
kyakoh great16:32
kyakkick out something useless, add in cyrillic :)16:33
mth"font" format here is C source for inclusion in the kernel16:34
mthnot sure what kind of format the user space tool wants16:34
mthbut it shouldn't be hard to adapt the scripts16:34
mththey need the Python Imaging Library installed, by the way16:34
mthI didn't feel like writing an image decoder16:35
kyakit,s easy to convert between kernel c and usespace font16:35
kyakplease kill the links yet, i,ll get to it in couple of days16:36
kyakdont,t kil)16:36
mthit's called "temp" because it won't be around forever, but probably it will take a few years before I remove them16:36
kyakgood :)16:37
kyakwhere did you find the fork btw?16:37
mthI forked it myself16:38
mthI wrote the tools this morning16:38
kyakhehe, pretty awesome!16:38
mthand edited the PNG version in GIMP16:38
mth1x1 square tip pencil, "x" to swap black and white16:38
mthat 400% zoom16:39
kyakit,s similar to what we do with setfont216:39
kyaksetfont2 is a code name for that colored font if you wonder16:40
mthah, I thought it was a package for changing fonts16:40
kyakyou can have a look at according repo in qi git..16:40
kyakit,s a package too :)16:41
kyakplus kernel  patch16:41
kyakthe utility, kernel patch, the font and utils to create such fonts16:41
mthyou're using a 32x8 grid as well :)16:42
kyakyeah16:42
kyakso we get the same terminal size 16:43
mthand using pygame for image loading, instead of PIL16:43
kyakbtw setfont2 provides a 4x6 font16:43
kyakwhich it damn tiny as you can imagine16:44
mthwe were using a 4x6 font from the kernel source tree, but it was very hard to read16:44
mththen Ayla switched to 8x8, which was an improvement but 40 chars per line isn't much16:44
kyakthe regulat 4x6 font is not readable, but 4x6 from setfont2 is readable, though not for a very long time16:45
mthso we tried 6x11 which looked OK but 11 matches very poorly with a height of 24016:45
kyakthen your eyes start bleeding16:45
mthof course, as a prime number, 11 matches poorly with almost anything16:45
kyakyeah..16:45
mthbut 1 or 2 leftover pixels would have been OK, but it was over half a character16:46
kyakwhat a werid number to choose for whoever created that font16:46
mthit says it was intended for Macs, maybe they had hardware 6x11 chars?16:46
kyakthey have a weird?resolution, which divides by 11?16:47
mthI don't know16:48
mthI was never interested in Macs until they started running unix16:49
kyakhm. weren,t they running unix from the beginning?16:50
mthnope, only since OS X16:50
mthOS X has almost nothing in common with OS 9, at the code level16:50
mthit was a rebranded Next Step16:51
kyakinteresting! what was it before?16:51
mthhorrible ;)16:51
mthsome kind of cooperative multitasking16:51
mthwikipedia says 512 × 384 display; 384 % 11 == 1, so it's possible they used 11-high fonts on it16:51
kyakhehe16:52
mthI'm not sure if Macs even have a console-only mode though16:53
mthif it's only GUI, then the font height and screen res don't have to be connected16:53
kyakdo you know if their licensing had changed since they switched to unix?16:53
kyaklike.. they need to release the source code, don,t they?16:54
mthalmost everything they use is BSD licensed16:55
mthGCC is the exception, but they're moving away from that to clang16:55
mththey do release a lot of the sources, even if it's not required16:55
kyaki rememer their vertical resolution is something like 1440, which doesn,t divide by 11 )16:55
mthfor modern Macs, yes16:56
kyakwhy would linux kernel fonts support mac anyway?16:56
mthbut those render with subpixel positioning16:56
mthLinux runs on Mac hardware16:56
mthincluding old m68k ones16:56
kyakah..16:56
kyaksure..16:56
mthDebian has/had a m68k version, but the build machines could never keep up with new releases16:57
kyaknew releases of what?16:57
mthof upstream packages16:57
mthstill better then IA64, where we'd get build logs with internal compiler errors16:57
mths/then/than16:58
kyakso they had to reduce the number of supported archs? fuuny )16:58
mthI think they have a half-supported category, where they do the best they can but don't consider broken or unavailable packages a reason to delay Debian releases16:58
mth"we" == "openMSX team" here, by the way16:59
mthwe like to have our sources built on as wide a range of OS and hardware as possible17:00
kyakhave to google the openMSX thing )17:00
mthmost exotic combination we succeeded on was OpenBSD/Alpha, I think17:00
mthopenmsx.sf.net17:00
mthit's an emulator17:00
kyakmth: forgive me my ignorance, never heard of msx before17:05
kyaknow i read abot it)17:06
kyakso it,s an old school calculator, put it like that17:07
mthYamaha MSX machines were used in education in Russia in the 80's17:07
mtheven with a kind of network17:07
mthnot calculator, home computer17:07
mthlike C64, ZX Spectrum17:07
mthyou could connect it to a TV or to an RGB monitor17:08
mthand use it for games, for programming or for serious stuff17:09
kyaki read the hardware has been emulated on altera cyclone17:09
kyakthat, reallt cool17:09
mthand the sources for that are available, so it could be ported to Milkymist if the FPGA has enough gates17:10
kyakthats what i thought of17:11
kyakmth: so msx is really dead, it,s just a bunch of enthusiasts?17:11
mthit's been commercially dead since about 199017:13
mthbut still every year new games are released17:14
kyakreally amazing!17:14
mththis is the most popular competition for new games: http://msxdev.msxblue.com/?page_id=37817:14
mthI have to go now, talk to you later17:16
kyakbye, thanks for the talk!17:16
kyaki guess i can just install the emulator and go play these games.. pretty great, though im not of a gaming kind of guy17:19
Jay7ZX Spectrum is the best! :)18:18
Aylawhen I was a kid I had an Amstrad CPC18:20
Ayla... my father threw it away x_x18:21
kyakfirst time i saw a computer it was pentium I. When i was a kid a never had anything like that, not even a gaming console like NES18:22
kyakactauuly i still have this old peice of shit around18:25
kyakmy first computer18:25
kyakeven the fujitsu 611 Mb HDD18:26
kyakbut it,s still nothing like msx or zx spectrums which i completely misse18:27
kyakd18:27
Action: Jay7 had russian ZX clone (Delta 48k iirc)18:34
kyakdid you throw it away? :)18:41
Jay7kyak: it is broken :(18:52
Jay7so.. it was lost in time long ago :)18:52
kyakbut you have it for what matters.. fixing it is just finding a pair of straight arms :)18:53
Jay7yeah.. 18:54
Jay7btw, lot of people in zx.pp.ru are still making clones of ZX18:54
Jay7s/lot of// :)18:54
kyaki have dendy, the russian clone of nes as you defintely know.. but it,s unconnectable :)18:55
Jay7iirc, it was connecting to antenna18:55
kyaksome fucked up video out ..18:55
Jay7or to video input?18:55
Jay7ah..18:55
kyaki might wanna double check18:56
kyakdont remember for sure18:56
Jay7I've seen another dendy clone in local metro-cc.ru18:56
Jay7it have price about $20 :)18:57
kyakyep18:58
kyakit,s pretty much available now18:58
kyakand even the cartridges18:58
kyaki have sega as well.. but it,s all postfactum18:59
kyaki missed the era :)18:59
qi-botThe build was successful: http://fidelio.qi-hardware.com/~xiangfu/build-nanonote/openwrt-xburst.minimal-20120426-1605 22:01
