| 00:02:54 | [Saint] | Ugggh, I just re-read your question, and the massive list of comparators required for your use case are not trivial. |
| 00:03:56 | [Saint] | Though...it isn't /impossible/. Sec. |
| 00:05:40 | [Saint] | Hmmm, no, it's not as ugly as I thought...assuming this works. |
| 00:06:49 | [Saint] | %?if(%pp,<=,9)<0%pp|%pp> should work to zero-pad, which IMO is nicer than space-padding. |
| 00:09:10 | [Saint] | there's also %?and() for using logical comparators against multiple tags without nesting. |
| 00:09:17 | | Quit lebellium (Quit: ChatZilla 0.9.93 [Firefox 51.0.1/20170125094131]) |
| 00:10:54 | [Saint] | From memory the syntax is: |
| 00:10:54 | [Saint] | %?and(tag,tag,...,tag,tag,comparator,operator)<true|false> |
| 00:11:34 | [Saint] | %?and() will only fire if _all_ tags compared against the operator are true. |
| 00:12:19 | [Saint] | you can use %?or() to for comparisons you want to fire if _any_ of them are true. |
| 00:14:13 | [Saint] | There's also several other approaches that spring to mind. Mostly because I'm a lunatic. |
| 00:15:41 | [Saint] | Defining a separate viewport for this value and then using the text alignment tags is the most flexible case as it allows for both RTL text and values of arbitrary length. |
| 00:15:41 | amazoniantoad | [Saint], hey man the bluetooth module project worked! |
| 00:15:43 | amazoniantoad | thanks for your help |
| 00:15:58 | [Saint] | amazoniantoad: Not a problem, what route did you end up taking? |

| 00:21:34 | amazoniantoad | [Saint], I soldered to the aux input |
| 00:21:49 | amazoniantoad | Then soldered the power supply to the pcb board of the ipod |
| 00:22:05 | amazoniantoad | Next I just need to drill some holds or something in the back of the ipod |
| 00:22:15 | amazoniantoad | So I can turn the bluetooth on and get a signal out |
| 00:22:20 | amazoniantoad | It's crystal clear too |
| 00:23:59 | amazoniantoad | How can I add a list of artists to rockbox? I want to be able to have the option of searching by album v artist v playlists |
| 00:24:09 | amazoniantoad | All I can seem to do is add playlists though |
| 00:26:25 | [Saint] | This is precisely what the Database function is for. |

| 00:34:41 | chrisjj | [Saint], that didn't work, but this adjusted version |
| 00:34:55 | chrisjj | %?if(%pp,<,10)< %pp|%pp> |
| 00:35:11 | chrisjj | did, and gives a good result: http://i.imgur.com/iR0v7Wg.png |

| 00:36:01 | chrisjj | "That" being your 22:58. |
| 00:36:12 | chrisjj | I've just seen your 23:06. Thanks. |
| 00:36:48 | [Saint] | The "right" way to do this is to give this value its own viewport and use the alignment tags. |
| 00:37:35 | [Saint] | then it'll work with values of arbitrary length whether they're space padded, zero-padded, or otherwise. |
| 00:38:15 | chrisjj | This value is embedded in a line, so the viewport coordinates would be font-size dependent. |
| 00:38:47 | [Saint] | correct. but you should be specifying a specific font anyway. |
| 00:39:05 | [Saint] | allowing the user to use userfont makes for a very easily broken theme. |
| 00:39:23 | [Saint] | if a user loads a 40pt font it screws up the entire theme. |

| 00:41:04 | chrisjj | I was following the lead of the default theme cabbiev2, which uses the user's font choice. |
| 00:42:01 | chrisjj | However I take your point and if I release this, I'll switch to a known font size. Shame that can't allow the users choice of font family, though. |

| 00:43:53 | [Saint] | cabbie does somewhat of a compromise by allowing the use of userfont, but forcing a specific font when cabbiev2.cfg is loaded. |
| 00:44:16 | [Saint] | it allows for users to break the display at their discretion, which I'll admit isn't ideal. |
| 00:44:23 | [Saint] | I struggled with how exactly to handle that. |
| 00:46:45 | [Saint] | Another concern was size of the end binary, as including a font that doesn't make the users eyes bleed, which also has wide unicode glyph coverage, balloons the size of the shipped archive quite a lot. |

| 08:14:40 | amazoniantoad | IO spent the past 5 hours trying to get it to take again |
| 08:14:54 | amazoniantoad | Just got it, but now the bluetooth powers but the ipod doesn't. Could the battery just be low? |
| 08:15:05 | amazoniantoad | Should I charge it? I mean the screen wont turn on |
| 08:15:28 | Bilgus | which wire was it? |
| 08:15:45 | amazoniantoad | Black one |

| 08:16:25 | amazoniantoad | But if the bluetooth is turning on, my ipod should be okay right? |
| 08:16:36 | amazoniantoad | I'm kinda worried now because the screen wont turn on. |
| 08:17:32 | Bilgus | how long did you hold the soldering iron there? |
| 08:18:04 | amazoniantoad | Want to see a picture of the state of things? |
| 08:18:08 | Bilgus | 1st thing i'd do is disconnect the battery |
| 08:18:18 | Bilgus | sure |
| 08:18:31 | Bilgus | second thing i'd do is look for solder bridges |
| 08:19:17 | amazoniantoad | what are those? |
| 08:19:53 | Bilgus | and the 3rd is take your meter and set it to the diode function ->|- lower right and check across each diode |
| 08:20:29 | Bilgus | put one lead on the blue circle and the other on the other side of those black boxes top to bottom in that pic |
| 08:20:41 | Bilgus | then flip the leads and do it again |
| 08:21:03 | amazoniantoad | Bilgus, http://i.imgsafe.org/ee8cdb8a94.jpg |
| 08:21:03 | Bilgus | you should get a reading 100-300 one way and a reading of -1 or 0 the other |

| 08:22:40 | Bilgus | but i do see what looks like a solder bridge above them too |
| 08:23:08 | Bilgus | well what a diode does is block flow one way but not the other kinda like a one way valve |
| 08:23:19 | amazoniantoad | okay |
| 08:23:24 | amazoniantoad | ohhh |
| 08:23:25 | amazoniantoad | I see |
| 08:23:31 | amazoniantoad | So I need to move the wire to the left? |
| 08:24:02 | Bilgus | wire to the left? |
| 08:24:25 | Bilgus | I see right now that you have a solder bridge just above the blob in that pic |
| 08:24:36 | Bilgus | up and to the right |
| 08:24:54 | amazoniantoad | yeah |
| 08:25:00 | Bilgus | add some flux there and heat it up with your iron and it should cling to each pad |
| 08:25:04 | amazoniantoad | both of those black chips give me power |
| 08:25:23 | Bilgus | be sure to wipe your iron first though you don't want to add any more sodler |
| 08:25:24 | amazoniantoad | so am I trying to break the bridge? |
| 08:25:27 | Bilgus | solder* |
| 08:25:57 | Bilgus | to test diodes you need to d/c the battery and put meter on ->|- |
| 08:26:29 | Bilgus | and put one lead on your blob and the other on the grey side of those black rectangles |
| 08:26:37 | Bilgus | then flip and note the readings |
| 08:27:40 | Bilgus | should always have the power disconnected when doing things unless there is no way around it or you need to actually test for power |

| 08:45:11 | Bilgus | good blob of flux and touching your iron will make it separate |
| 08:45:18 | amazoniantoad | okay |
| 08:45:59 | Bilgus | now as for the diodes assuming you kep your leads the same way when you tested both diodes the one on the left is bad |
| 08:46:27 | Bilgus | but you need to test both like I said above |
| 08:46:38 | amazoniantoad | Well the one on the left is .04 |
| 08:46:44 | amazoniantoad | and the one on the right reads 3.84 |
| 08:46:57 | Bilgus | and when you flip your meter leads? |
| 08:47:07 | amazoniantoad | You mean switch black and red? |
| 08:47:11 | Bilgus | yes |
| 08:47:15 | amazoniantoad | let me try that now |
| 08:48:20 | amazoniantoad | one on left jumps from .03 to 1.59 |

| 13:01:10 | pamaury | wodz: no luck :( I found the proper sequence of enable sound, so at least I can always play sound, but it's still distorted |
| 13:02:05 | wodz | pamaury: What about mtp program? You said it produces undistorted sound (what kind of btw. beeps?) |
| 13:02:14 | pamaury | beep |
| 13:02:42 | wodz | pamaury: alright. beeps are generated in hardware by loading proper program into dsp |
| 13:03:13 | pamaury | well in the case of mpt I'm not so sure |
| 13:03:39 | wodz | pamaury: seems like sony has proprietary ioctl for this |
| 13:03:45 | pamaury | I disassembled the code and as far as I can tell, the only way it interacts with alsa is though the mptapp_mixer.sh and and aplay |
| 13:04:20 | pamaury | and if you look at the mixer script, it uses amixer to tweak controls and aplay to play some audio files in /usr/local/share |
| 13:05:38 | pamaury | I also disassembled the OF and the audio code is really complicated. But I found the "Builtin" audio startup sequence and it matches what I came up with, basically: |
| 13:05:38 | pamaury | amixer set cname='CODEC Power Switch' 1 |
| 13:05:46 | pamaury | amixer set cname='CODEC Mute Switch' 0 |
| 13:06:16 | pamaury | amixer set cname='Playback Src Switch' 1 # can't remember the exact name, 1 is for 'Music' |
| 13:06:30 | pamaury | and then the regular alsa stuff |
| 13:07:58 | wodz | pamaury: but then mptapp_mixer.sh implies you could simpy play wav |
| 13:08:25 | pamaury | yeah, and when I do it doesn't work, sound is distorted |
| 13:14:09 | wodz | pamaury: Is noican == noise canceling HP? |

| 13:31:32 | pamaury | I'm wondering if it's possible that the pcm is broken and only expects 32-bit samples |
| 13:31:53 | pamaury_ | I will test this theory tonight |
| 13:32:21 | wodz | pamaury_: silence32.wav is the only wav on device |
| 13:32:43 | pamaury_ | yes I know |
| 13:35:26 | pamaury_ | I'm still studying the code of mtpapp and OF to see what they do with the dsp stuff |

| 13:36:15 | wodz | pamaury_: This file is not silence it is a noise :P |

| 13:37:17 | pamaury_ | I mean in mptapp |
| 13:37:25 | wodz | pamaury_: you mean by aplay? |

| 13:45:32 | pamaury_ | I left my player at home so I don't have the exact code but you should be able to figure it out ;) |
| 13:46:13 | pamaury_ | also the dsp stuff is very confusing, the OF opens two devives: /dev/dsp and /dev/sound/dsp and I can't figure out from the sony headers which ioctl applies to what |
| 13:52:28 | | Join Senji [0] (~Senji@85.187.103.250) |
| 13:52:37 | * | pamaury_ remembers that /dev/dsp is the old OSS stuff |
| 13:55:44 | wodz | pamaury_: aplay outputs noise for this file. I can't tell for sure but sounds similar enough to my PC so I can't tell the difference. |
| 14:00 |
| 14:00:11 | pamaury_ | wodz: you could try to convert an audio file to wav in 16-bit signed stereo and also in 32-bit signed stereo and try both with aplay ? |
| 14:00:26 | * | wodz just trying |
| 14:02:51 | wodz | pamaury_: 16bit wav plays just fine (minus fact that bitrate is wrong. I bet sony expects 48kHz and I dumped 44.1kHz one) |
| 14:04:05 | wodz | hmm, maybe I screwed conversion |
| 14:05:22 | pamaury_ | wodz: apaly is supposed to tell the pcm driver the sample rate and all |
| 14:05:46 | pamaury_ | but now I'm quite convinced that the driver is now following orders correctly |
| 14:05:49 | pamaury_ | *not |
| 14:05:55 | wodz | pamaury_: What kind of distortion it was? |
| 14:06:28 | wodz | pamaury_: No I screwed export to wav apparently. The file advertised itself as 32kHz despite being 44.1kHz |
| 14:07:10 | pamaury_ | wodz: I can't tell exactly |
| 14:07:16 | pamaury_ | it's just...wrong |
| 14:07:40 | wodz | pamaury_: Sonding like overdrived? Or totally scrambled or what? |
| 14:09:38 | wodz | BTW. working for me init sequence: amixer cset iface=MIXER,name='CODEC Power Switch' 1; amixer cset iface=MIXER,name='CODEC Mute Switch' 0; amixer cset iface=MIXER,name='Playback Src Switch' 1 |
| 14:10:42 | pamaury_ | not you can recognize the sound but something is not right, it sound saturated and I'm not sure the sampling rate is correct. But it might just be a problem with the sampling rate |
| 14:11:49 | wodz | pamaury_: The sound could be distorted here as well, I just don't know very well rockbox test tune to tell. |
| 14:12:56 | wodz | pamaury_: Do you have a clue what is 'CODEC Acoustic Switch' ? |
| 14:13:26 | pamaury | wodz: try with a music you know |
| 14:13:31 | pamaury | no clue |
| 14:13:46 | wodz | pamaury: I don't have here any file I know well enough |
| 14:16:22 | wodz | pamaury: amixer cset iface=MIXER,name='CODEC Acoustic Switch' 1 seems to make difference. The sound is clearer without saturation |
| 14:16:49 | wodz | hell, I don't have cable to record it back and compare :/ |
| 14:18:28 | pamaury_ | the acoustic setting is directly forwarded to the codec driver, you'll have to RE it to find out |
| 14:19:34 | wodz | pamaury_: I think it will be easier to record samples and compare to originals |
| 14:19:40 | pamaury_ | yeah |
| 14:20:06 | wodz | it very well might be some funky switch with wrong name |

| 22:23:03 | pamaury | It's still a hack for now, using system("amixer ..."); but at least I can reliably play sound and it's not distorted |
| 22:23:22 | wodz | pamaury: big step forward indeed |
| 22:23:46 | pamaury | there are few annoying things though: Sony exports the volume as a percent instead of dB |
| 22:23:59 | wodz | pamaury: How is this is done in amixer? some ioctl? |
| 22:24:06 | pamaury | amixer |
| 22:24:22 | pamaury | using the 'standard' playback volume |
| 22:24:43 | pamaury | there might be other ways, I don't know |
| 22:24:52 | pamaury | does the codec expose the registers to userspace ? |
| 22:25:17 | pamaury | also what the hell is acoustic mode ?? |
| 22:27:03 | wodz | pamaury: looking at cs47l01_d.ko I think it exposes codec registers somewhere in /proc. This is not very useful though as I can't find any documentation about cs47l01 |
| 22:29:45 | pamaury | it might be close enough to other codecs that with RE we figure some things out ? |
| 22:30:11 | pamaury | it's a bit strange that google does not seem to know *anything* about cs47L01 |

| 23:05:41 | wodz | __builtin: Extend this to more target is a matter with adding export symbol defines to target specific sources. But then problems starts - the next step would be to dynamically allocate plugin/codec buffer. I didn't reach that stage. |
| 23:06:59 | wodz | __builtin: And 'module symbol dependencies' are not touched - I mean it should be possible to load 'module' which exports some symbol needed by other module (just like dependent modules in linux kernel) |
| 23:08:58 | lebellium | pamaury: congrats! I knew you wouldn't need more than 24 hours to fix any issue :D |
| 23:10:13 | pamaury | we still don't understand why it works though... |
| 23:10:23 | pamaury | lebellium: does 'Acoustic mode' rings a bell ? |
| 23:10:50 | lebellium | There is no "acoustic mode" in OF |
| 23:10:59 | lebellium | or at least not called like that |

| 23:33:18 | Bilgus_ph | you know __builtin i didn't even think about it being a 64 bit sim maybe i should make it explicit with uint8 just to be sure. also im pretty sure rolling the buffer will break .pgn saving but since partial games weren't saved anyways it isn't too high on my list |
| 23:35:03 | [Saint] | I looked at the chessbox.rock source, and my God you weren't kidding were you Bilgus_ph... |
| 23:35:15 | [Saint] | I'm really surprised that ever worked. |
| 23:35:32 | [Saint] | Actually, I'm not confident it ever did. |
| 23:36:27 | __builtin | ideally the whole plugin needs a rewrite |
| 23:37:27 | __builtin | I looked at it and it is not something that facilitates easy debugging, or even reading |

| 23:39:29 | Bilgus_ph | Yeah I CALLS NOT IT |
| 23:40:43 | __builtin | maybe I'll find a good SDL chess program to port and replace it :D |
| 23:41:40 | __builtin | the current engine is very strong, though |
| 23:42:03 | __builtin | I've never managed to beat it, or even gain an advantage on it |
| 23:42:12 | Bilgus_ph | Agreed |
| 23:43:46 | __builtin | good, so it's not just me! :D |

| 23:55:13 | __builtin | Bilgus: one thing regarding uint8_t, though |
| 23:55:22 | __builtin | sizeof(char) is guaranteed by the standard to be 1 |
| 23:55:27 | __builtin | and char is almost always 8 bits |
| 23:56:35 | __builtin | and if it's not, we have bigger issues than that :P |
