| 00:10:09 | webguest87 | Hello all |
| 00:10:17 | Bagder | hi |
| 00:11:08 | webguest87 | a quick question for the Bagder administrator :) |
| 00:12:04 | webguest87 | why in the CVS buil table, the 2 colums of the Gmini port still apear ? |
| 00:12:19 | Bagder | because the columns are based on more data than what is shown |
| 00:12:21 | webguest87 | i know it's not important |
| 00:12:52 | webguest87 | are will always here? |
| 00:12:56 | Bagder | no |
| 00:13:19 | webguest87 | i know this port is in "stand by" |
| 00:14:25 | Bagder | I would call it abandoned |
| 00:14:48 | webguest87 | :) anyone worked on it since long time? |
| 00:14:55 | Bagder | nope |
| 00:15:00 | Bagder | been months since |
| 00:15:10 | webguest87 | ok |
| 00:15:31 | webguest87 | there was just one dev worked on it? |
| 00:15:38 | Bagder | yes |
| 00:16:08 | webguest87 | difficult to port Rockbox alone, no? |
| 00:16:20 | Bagder | his computer broke down |
| 00:16:28 | webguest87 | :( |
| 00:16:31 | Bagder | and he couldn't afford a new one |
| 00:16:48 | webguest87 | not good for him |
| 00:17:09 | webguest87 | personaly i'm iriver user |
| 00:17:21 | webguest87 | one very happy user :) |
| 00:17:25 | Bagder | :-) |
| 00:18:18 | webguest87 | i read in the logs of today maybe Slasheri'll go to imlement paek meter things |
| 00:18:27 | webguest87 | it's very good |
| 00:18:44 | webguest87 | *peak |
| 00:19:31 | webguest87 | i love your Rockbox fw :) |
| 00:19:40 | Bagder | thanks |
| 00:20:25 | webguest87 | and i love his "association" with the GPL concept |
| 00:20:45 | webguest87 | not money way |
| 00:20:54 | webguest87 | and free to code |
| 00:22:39 | webguest87 | Bagder: think you in the futur (soon i hope), it'll be possible to have got a beep option like the original fw or most of music players? |
| 00:22:52 | webguest87 | it's not a request just question :) |
| 00:23:00 | Bagder | what would that do? |
| 00:23:17 | Bagder | I mean, when would it beep? |
| 00:23:28 | Bagder | but yes, surely we can make it beep |
| 00:23:39 | webguest87 | when pushed a key |
| 00:23:57 | Bagder | oh |
| 00:24:08 | Bagder | I always disable such stuff |
| 00:24:13 | webguest87 | like mostly player music |
| 00:24:14 | Bagder | on every device I own |
| 00:24:44 | webguest87 | you don't like it? |
| 00:25:03 | Bagder | I hate it |
| 00:25:22 | webguest87 | :), scuse for this evocation in your brain :) |
| 00:25:26 | Bagder | hehe |
| 00:25:35 | Bagder | well, that's what options are for |
| 00:25:52 | webguest87 | but it be very usual for lot of people i assume |
| 00:26:01 | webguest87 | true |
| 00:26:24 | webguest87 | think you it'll be dificult to add to options? |
| 00:27:08 | Bagder | I would guess that the most difficult part is to find someone who'll write the code for the feature |
| 00:27:58 | webguest87 | yes i assume, just if one dev work on it, needed lot of codes? |
| 00:28:08 | webguest87 | lot of time? |
| 00:28:16 | webguest87 | for him |
| 00:28:31 | Bagder | that would depend on the coder of course |
| 00:28:40 | webguest87 | :) of course |
| 00:29:24 | webguest87 | for example, you, you are an experimented hackers |
| 00:29:37 | Bagder | no, it would not take very long |
| 00:30:45 | Bagder | sleep time |
| 00:30:58 | webguest87 | have a good night |
| 00:31:40 | webguest87 | thanks for your answers |

| 11:37:34 | Slasheri | Hmm, my current implementation of the peak meter looks more like a spectrum meter.. |
| 11:38:28 | Lear | Too fast? |
| 11:39:38 | Slasheri | nope, it meters one fixed frequency.. Maybe something like 4 kHz |
| 11:39:50 | Slasheri | i will try to fix that |
| 11:40:01 | Slasheri | for example it igrones bass totally |
| 11:40:34 | Lear | Aren't you just looking at peak sample values? |
| 11:41:10 | Slasheri | hmm, we dont have peak values but we have to calculate tehm? |
| 11:41:54 | | Quit cYmen (Read error: 104 (Connection reset by peer)) |
| 11:41:54 | Lear | How else would you do it? |
| 11:43:19 | Slasheri | Hmm.. currently i try to find min and max sample values between a specified period and then calculate average peak value for a longer period |
| 11:45:39 | Lear | Doesn't the peak meter do some averaging as well? |
| 11:45:51 | Slasheri | maybe i should first find the bias value and then base the peak readings on that |
| 11:46:00 | Slasheri | then it might work better |
| 11:46:39 | Slasheri | maybe, but it takes samples only ~20 times per second |
| 11:46:53 | Slasheri | so we have to calculate some average also |
| 11:49:42 | Slasheri | current implementation works well for higher frequencies but its more an eq analyzer than a peak meter |

| 17:23:44 | Slasheri | Lear: that was easy to fix, i will commit soon :) |
| 17:26:52 | Coldtoast | about 3 days ago I was listenign to tracks and instead of tracks crossfading, I got the start of the next song, a burst of the last song then the rest of the next song. Ithink it was after buffering then changing to a different dir, listening for a few secs then skipping to the next track |
| 17:27:29 | Coldtoast | so kind of a "worst case scenario" for playback |
| 17:27:50 | Moos | i experimented this too few days ago :( |
| 17:28:02 | crwl | i've got stuff like that too, and i don't use crossfading |
| 17:28:03 | Coldtoast | once it buffered again tho, it was fine |
| 17:28:33 | crwl | not buffering enough initially or something (this only happens sometimes when changing tracks to something that isn't buffered yet) |

| 17:55:26 | Tangleding | slasheri sorry |
| 17:55:52 | Tangleding | ? |
| 17:56:24 | Slasheri | Tangleding: hi, yes i am :) |
| 17:56:31 | Tangleding | Hello |
| 17:56:33 | Tangleding | :) |
| 17:56:36 | Tangleding | How are you? |
| 17:56:38 | Tangleding | :) |
| 17:57:22 | Slasheri | fine thx ;) just trying to catch the last bugs before i leave for few weeks :) |
| 17:57:28 | Tangleding | :) |
| 17:57:29 | Tangleding | nice |
| 17:57:37 | Tangleding | about the gapless fix |
| 17:57:40 | Tangleding | precisely |
| 17:57:48 | Tangleding | it's conceerning ogg i guess? |
| 17:57:56 | Tangleding | no lame? |
| 17:59:24 | Slasheri | all codecs had the problem, but it doesn't mean lame would be totally gapless now |
| 17:59:50 | Slasheri | at least other codecs should be true gapless |
| 18:00 |
| 18:00:01 | Tangleding | ah okay |
| 18:00:26 | Tangleding | lame is really diffrent from others concerning gapless issue? |
| 18:00:55 | Slasheri | yes it's because mp3s are not designe to be gapless.. |
| 18:01:58 | Tangleding | in fact i've discussed with Gabriel Bouvigne |
| 18:02:09 | Tangleding | (a Lame developer) |
| 18:02:19 | Tangleding | and according to him |
| 18:02:33 | Tangleding | the mainly différence was a "standadisation" one |
| 18:02:36 | Lear | LAME-encoded stuff can be gapless, but it is something tacked on later. |
| 18:02:48 | Tangleding | since there are many encoders |
| 18:02:58 | Tangleding | unlike Vorbis for exemple |
| 18:03:38 | Tangleding | he told me that thje vorbis gapless feature was using same method thanrecent lame (with fixed delay) |
| 18:03:43 | XavierGr | so its pretty much impossible to see gapless to non-lame mp3s right? |
| 18:03:56 | Tangleding | i guess so |
| 18:04:01 | Tangleding | would be necessary |
| 18:04:23 | Tangleding | to set the delay according to each encoder |
| 18:04:27 | Slasheri | XavierGr: we may have the dsp to detect and cut silence in future |
| 18:04:36 | XavierGr | :) |
| 18:04:39 | Lear | Yes, because the decoder doesn't know how much the source was padded. Encoder delay isn't fixed either. |
| 18:05:01 | Tangleding | oit's fixed for lame anyway |
| 18:05:20 | Tangleding | have you got contact with some of the lame developers? |
| 18:06:02 | Lear | Problem is, how to not detect/cut silence not at the very end... |
| 18:08:00 | XavierGr | LinusN: Do you happen to from where the tree.c code is executed? I found the tree_init function called by main.c but this isnt most likely |
| 18:08:13 | XavierGr | ^happen to know |
| 18:08:17 | Tangleding | A cool feature about silence remover |
| 18:08:38 | Tangleding | should allow to detect long silence not only at the file end |
| 18:08:49 | Tangleding | (for kinda bonus track ;) ) |
| 18:09:00 | LinusN | XavierGr: app_main() calls init() and then browse_root() |
| 18:09:30 | XavierGr | thanks |
| 18:11:28 | XavierGr | so if I make a remote-tree.c identical to tree.c (cahnged lcd_ functions to remote_lcd) and call remote_tree_init() and remote_browse_root() (changed respectively) I can get the remote working right? (then toss up the clutter code) |
| 18:12:56 | Lear | Except having two browsers active at the same time sounds like a bad idea... The remote should mirror a clipped version of the main display, IMO. |
| 18:13:37 | LinusN | Lear: agreed |
| 18:14:24 | | Quit CBM-away (Read error: 54 (Connection reset by peer)) |
| 18:14:27 | XavierGr | Well amiconn suggested that we use a saperate thread for each. Like creating remote-tree.c remote-wps-display.c e.t.c |
| 18:14:39 | Tangleding | how do the iRiver fw proceeds? |
| 18:15:28 | Lear | That might work, but it could also be confusing (for the user), and wouldn't there be synchronization issues? |
| 18:18:11 | XavierGr | well I started a quick hack by replicating every lcd_ function to lcd_remote in the tree.c but encountered a dead end. Where a a function returns the height of the screen. I cant find a way to return 2 values, 1 for the main unit and for the remote. So I thought a different .c file would be better. |
| 18:18:59 | XavierGr | what do you suggest? |
| 18:19:38 | Lear | what functions do you refer to? |
| 18:19:58 | XavierGr | you mean the lcd_ ones? |
| 18:20:15 | XavierGr | or the replicate_height()? |
| 18:20:42 | Lear | the ones you had problems with |
| 18:23:13 | XavierGr | in tree.c line 239 recalc_screen_height. int height, is returned with the height value of the screen (LCD_HEIGHT) but then the remote screen isnt displayed correctly (text is hidden in the bottom part) |
| 18:23:14 | Lear | hm... separating tree into a model and a view sounds like one way of doing it. I.e., tree (and also the wps) maintains a model over what to display, then call on functions to draw that model, once for the main display, and once for the remote, if present. |
| 18:24:28 | XavierGr | so if I change height = REMOTE_LCD_SCREEN the remote is displayed correctly but the main is not |
| 18:24:32 | Lear | yes, you need to maintain two values (using arguments to return the value or indicate what you want, different functions,etc) |
| 18:26:03 | XavierGr | so what to do. 1.replicate and adjust 2.make another file for the remote |
| 18:26:40 | Lear | 3. split out the rendering code into two cases, main and remote |
| 18:27:15 | XavierGr | in the same tree.c? |
| 18:27:40 | Lear | could be, but that isn't a requirement... |
| 18:28:03 | Lear | the point is to logically separate the rendering from the rest. |
| 18:28:54 | XavierGr | a complete rewrite as I see it... I will have to understand each and every line of the code... and I am newb. nevertheless i will try. |
| 18:30:01 | Lear | no, not a complete rewrite. Lots of restructuring, yes... |
| 18:30:57 | XavierGr | to rewrite tree.c for the screen height is tricky though. I tried many times but the rendering functions must be run twice for every display. |
| 18:32:11 | Lear | no, once per display should be enough. :) |
| 18:32:38 | XavierGr | yeah my bad I meant twice, once for each display |
| 18:33:21 | Lear | but there is no other way, because the screens need to be rendered differently. |
| 18:34:06 | Lear | and the easy way to handle that is to put the rendering in separate functions. |
| 18:34:52 | XavierGr | though amiconn said clearly to me to make a different thread, not just a quick replicate hack, but then I will have to make a huge restructural work in order not to duplicate unnecessary code... |
| 18:35:53 | XavierGr | so I could make a remote-tree.c which has the rendering functions for the remote and then call them from the tree.c if there is a remote? |
| 18:35:59 | Lear | personally, I don't see the need for a separate thread... I guess the restructuring needed is why nobody has cared enough just yet. :) |
| 18:36:38 | XavierGr | LinusN: What do you think? |
| 18:36:55 | Lear | yes, something like that. Only I'd always call them, and let them return immediately if there is no remote. |
| 18:37:43 | LinusN | XavierGr: i agree with Lear |
| 18:38:32 | XavierGr | but what if the code in tree.c is not saperated with rendering/setup functions. It is most likely that they are mixed up. |
| 18:39:08 | XavierGr | I will have to dig up a little to be sure |
| 18:39:18 | Lear | the code sure isn't separated today, but it needs to be... |
| 18:40:43 | XavierGr | Pitty because I quite sure that I will have troubles to saperate them or even likely to understand them... |
| 18:41:06 | Lear | to a large degree, I think what is needed is a "render list" function, that based on the loaded directory, cursor position and an internal state (the top line) draws that list. |
| 18:42:51 | XavierGr | god the remote thing is the only thing that keeps me away from using rockbox. I am dying to make something for it. |
| 18:44:03 | Lear | A few additional things are needed though,e.g., the "create playlist" splash. Some could problably be made with splash() (which perhaps also should know how to handle an additional display). |
| 18:44:57 | XavierGr | another question: a static is seen without change in a single .c file, right? What if I want to use a static variable from another file? |
| 18:45:28 | Lear | I'd start by going through all rendering (lcd calls) and try to group them logically. As in, render tree, create playlist... |
| 18:46:56 | XavierGr | truth is that not all functions in tree.c has and lcd rendering function. |
| 18:46:59 | Lear | A static is only visible within that module, yes. If you want access from another file, use accessor functions. dsp_stereo_mode() is a good example. It returns the current stereo mode, which is maintained within dsp.c. |
| 18:47:28 | Lear | well, then perhaps they don't need to be changed at all? |
| 18:47:44 | XavierGr | but it has some huge ones that do many things. |
| 18:47:50 | Lear | i.e., there's no rendering to break out. |
| 18:48:10 | XavierGr | also they counter react with other files for various tasks. |
| 18:48:43 | Lear | but those things can be grouped into a limited number of "functions"... |
| 18:49:57 | XavierGr | 7 functions have at least one lcd rendering function |
| 18:50:33 | XavierGr | and dirbrowse is HUGE also there are alot of ifdes which need to be removed for the remote. |
| 18:52:42 | Lear | But most of that is non-render logic, afaict. The "model" part I mentioned before. |
| 18:54:28 | XavierGr | how can I return 2 values from a function? Maybe as a void functions which alters 2 static values? |
| 18:55:48 | Lear | on a tangent, shouldn't the lcd_puts_scroll code be common to all targets? And wasn't it, once upon a time... :) |
| 18:56:14 | Lear | pass in a pointer, and set the value through that pointer, |
| 18:57:40 | Lear | see e.g. get_tag, it sets flags that way |
| 18:57:51 | Lear | (in wps-display.c, that is) |
| 18:59:15 | XavierGr | ok thanks. I will think of this a little bit and I will see what I can do... |

| 19:12:44 | Slasheri | XavierGr: no.. i have to go to the mandatory (civil) military service.. :D |
| 19:15:03 | XavierGr | for how long? |
| 19:16:30 | Slasheri | 13 months and one month (3 weeks in fact) without net access |
| 19:17:02 | Slasheri | but i can do other things during that 12 month period too :) |
| 19:17:30 | XavierGr | so we will see you again after 13 months!!!!! |
| 19:17:43 | Slasheri | hehe :D |
| 19:17:52 | XavierGr | we will surely miss you.... :( |
| 19:18:00 | Slasheri | after one month could be more realistic i hope ;) |
| 19:18:28 | XavierGr | but you said 12 months? |
| 19:18:41 | Slasheri | yes, the service lasts 13 months |
| 19:19:01 | XavierGr | you will have some breaks? |
| 19:19:06 | Slasheri | but during that last 12 month period i have the net access and can do other things too if i have time :) |
| 19:19:09 | XavierGr | ^brakes |
| 19:19:22 | thegeek | do as I did |
| 19:19:24 | thegeek | get lucky |
| 19:19:29 | thegeek | and get out after 7 months |
| 19:19:33 | Slasheri | hmm :D |
| 19:19:40 | thegeek | because of bad economy |
| 19:19:47 | thegeek | they just had to dump some of us |
| 19:19:47 | Slasheri | hehe, nice ;D |
| 19:19:50 | XavierGr | how old are Slasheri? |
| 19:19:51 | thegeek | indeed:) |
| 19:19:55 | Slasheri | XavierGr: 20 :) |
| 19:20:24 | XavierGr | and going to military so soon? I am 21 and I will go in 2011! |
| 19:20:48 | Slasheri | oh :) i just wanted to go there as soon as possible.. then i don't need to worry about it later :) |
| 19:20:49 | Ismo | Slasheri: inspired by your latest commit I browsed the playback.c a bit. Is the line 1349 correct or should there be some if statement before that? |
| 19:21:04 | Slasheri | Ismo: Hmm, i will check that |
| 19:21:59 | Ismo | I haven't looked how the pcm stuff works, but that line looks like a bit too alone :) |
| 19:22:01 | Slasheri | Ismo: yes, that's correct. If we were filling the buffer, AUDIO_PLAY event will start the crossfade |
| 19:22:08 | Slasheri | and if not, then it's started there |
| 19:22:16 | Slasheri | :D |
| 19:22:19 | Ismo | ok |
| 19:22:21 | Ismo | :) |
| 19:23:03 | Slasheri | in fact codec_track_changed() could be on that statement too but it's outside it because in every case we want to update the wps immediately |
| 19:23:33 | XavierGr | and what country are you from Slasheri? |
| 19:23:41 | Slasheri | XavierGr: from Finland :) |
| 19:24:00 | XavierGr | I thought that is was voluntarily there. |
| 19:24:19 | Slasheri | this is the about only EU country that still has mandatory mil service.. :/ |
| 19:24:36 | thegeek | hey! |
| 19:24:37 | XavierGr | well count Greece in that too |
| 19:24:39 | thegeek | dont forget norway |
| 19:24:42 | thegeek | or sweden |
| 19:24:45 | XavierGr | haha |
| 19:24:45 | thegeek | oh |

| 19:24:47 | thegeek | oh well |
| 19:24:48 | Slasheri | :D |
| 19:24:50 | thegeek | sweden then |
| 19:25:26 | XavierGr | its 12 months (i think) mandatory here too. |

| 21:20:53 | Slasheri | i think the scaling might not be right and for some reason i have to "invert" the calculated average to get the right reading. You will find more from the code :) |

| 22:24:41 | ep0ch_ | the peakmeter is wierd... even quiet parts of the music show full peak |

| 22:28:56 | ep0ch_ | nah i dont think it was changing the peakmeter that broke the sound.. did it again and it worked... |
| 22:29:46 | Slasheri | if you have logf enabled, take a dump and try to see what happened |

| 22:30:54 | ep0ch_ | heh |
| 22:30:59 | Slasheri | :D |
| 22:35:33 | stripwax | Slasheri - yes, that was my approach too but I remember Linus saying it was quite strange so I guess I thought an approved approach would have to be different ;-) |
| 22:36:01 | Slasheri | ah, interesting :) |
| 22:36:55 | stripwax | Slasheri - how do you work around something like SAR0 changing while you're reading the buffers? or the remaining buffer size being less than your averaging window? |
| 22:37:31 | stripwax | Slasheri - i think my patch was here http://www.beermex.com/@spc/vu.patch |
| 22:38:26 | ep0ch_ | so basically you average a block of samples, divide by the bit depth and mutiply by the number of pixels wide the peak meter is, or something? |
| 22:39:20 | stripwax | ep0ch_ - sort of, the recorder/peakmeter.c code just expects a number between 0 and 0x7fff |
| 22:39:41 | ep0ch_ | ok |
| 22:40:02 | stripwax | so yeah, we average a bunch of sample data, and obtain a left and right 'volume' value between 0 and 32767 |
| 22:40:32 | ep0ch_ | sample data is signed? |
| 22:41:20 | stripwax | ep0ch_ - would that make any difference? volume would still be between and 0 and 32767 |
| 22:41:54 | ep0ch_ | if you have sample values, -255 and 255 average is 0 |
| 22:42:01 | ep0ch_ | when it should really be 255 for the peakmeter |
| 22:42:11 | ep0ch_ | i.e. the average of 255 and 255 |
| 22:43:01 | ep0ch_ | so you should ignore the sign if sample data uses it? |
| 22:43:16 | ep0ch_ | bah i'll look at some C code and see if i understand it :) |
| 22:43:21 | stripwax | ep0ch_ - ah, understood. yes, to derive the sample data obviously we need to know what 'zero value' means. |
| 22:43:45 | stripwax | I think I assumed sample data was 16 bit signed in my code, dunno what Slasheri does |
| 22:44:45 | stripwax | Hmm - interesting, he's assuming sample data is unsigned, but only deriving a volume value from samples with value > 32768. weird? |
| 22:45:51 | ep0ch_ | well half the values wont be calculated then |
| 22:46:15 | stripwax | well, they'll be calculated but wrong ;-) |
| 22:46:43 | ep0ch_ | should average the whole lot and add 32768 to the total maybe |

| 22:56:28 | ep0ch_ | :) |
| 22:59:54 | ep0ch_ | stripwax: back to peakmeter, if the data is unsigned taking the average of absolute values is pointless |
| 23:00 |
| 23:01:11 | stripwax | ep0ch_ - audio data is 16 bit.... if data is unsigned then 'zero' is 32768. so subtract 32768. and then it becomes signed. so you need to take absolute values... |
| 23:01:12 | Lear | epoch_: pcm data is signed. |
| 23:01:31 | Lear | at least in the iRiver... :) |
| 23:01:32 | stripwax | (or, equivalently, invert data if sample is > 32768) |
| 23:02:23 | memmem | No, the result of inverting will be off by one. |

| 23:05:08 | stripwax | and not unsigned shorts, which is what Slasheri's pcm vu meter code seems to use.. |

| 23:07:05 | Bagder | I didn't even know it could do that ;-) |
| 23:07:14 | stripwax | BBub the original firmware loads the entire directory structure on startup, which is time and battery consuming ;-) |

| 23:14:46 | Bagder | memmem: we have no good mp3 encoder that runs fast |
| 23:15:22 | Bagder | so currently we don't see that coming any time soon |
| 23:15:34 | memmem | Ditto for OGG? |
| 23:15:43 | Bagder | yes afaik |
| 23:15:44 | BBub | better chances for recording in flac/wavpack ? |

| 23:15:54 | Bagder | BBub: yes indeed |
| 23:16:01 | BBub | oh, that sounds nice |

| 23:38:24 | amiconn | Yes, way less flicker than on archos |
| 23:38:32 | Bagder | cool indeed |
| 23:38:44 | amiconn | ...because it flicks between 2 adjacent native grey levels, not black & white |
| 23:39:03 | stripwax | amiconn - that doesn't require constant CPU boost or anything silly does it? |
| 23:39:25 | amiconn | The experimental thing is without random pixel pattern shift, so more levels would flicker |
| 23:39:41 | amiconn | I hope to support 97 levels of grey in the actual lib |
| 23:40:13 | amiconn | stripwax: Yes it requires constant boost, unfortunately. That's why it will be plugin only, like on the archos |

| 23:41:51 | amiconn | The method quickly switches between several bitplanes. The maximum number is limited to 32 to allow storing the pattern in a longword for quick access |
| 23:42:20 | amiconn | On archos, this allows 33 shades of grey, with the lcd being b&w only |
| 23:42:37 | amiconn | ((2-1) * 32 + 1) |
| 23:42:53 | amiconn | The iriver lcd already provides 4 shades natively, so |
| 23:43:01 | Rick | yummy yummy :) |
| 23:43:04 | amiconn | (4-1) * 32 + 1 = 97 |
| 23:43:55 | memmem | The X5 display supports 2^18 colors (and I confirmed that the firmware transfers 2^18 bits per pixel to the LCD controller). |

| 23:46:57 | amiconn | We should still try to find the type, complete with a datasheet |
| 23:47:12 | Rick | the x5 looks slick |
| 23:47:17 | memmem | Of course. There are probably also some I/O pins involved. |

| 23:47:35 | memmem | such as? |
| 23:47:38 | amiconn | ...like (simple example) the display flip |
| 23:47:47 | memmem | What's that? |
| 23:47:54 | Rick | flipping the display |
| 23:47:57 | Rick | so its upside down |
| 23:48:13 | amiconn | All pixel based units have a mode to use the unit upside down |
| 23:48:26 | memmem | That could also be done in software. It's used rotated 90 degrees anyway. |
| 23:48:35 | | Quit Coldtoast ("Peace and Protection 4.22") |
| 23:48:41 | Rick | wouldn't hardware be faster though? |
| 23:48:48 | amiconn | That's useful from time to time, and since it uses a hardware feature of the controller, it's simple... |
| 23:49:43 | amiconn | memmem: Doing it in software would be quite a bit more complex |

| 23:50:00 | memmem | If all drawing operations go through a display buffer there's no difference. Just subtract 160 instead of adding 160. |
| 23:50:28 | stripwax | memmem - does that mean an extra test for EVERY pixel operation? or does it mean two functions where one would suffice? :-p |
| 23:50:29 | amiconn | They go through a display buffer with the same layout as the internal buffer of the lcd |
| 23:50:44 | amiconn | ...and it's not as simple |
| 23:50:57 | Rick | right...because then you would have to rearrange data |
| 23:51:11 | amiconn | (1) Flipping the line blocks is simple, as ou said just invert the line sequence |
| 23:51:12 | stripwax | ok, just submitted another useless patch - this one for Cube plugin lets you rotate the cube manually when it's paused |
| 23:51:15 | memmem | The iAUDIO firmware's buffer has a different format than expected by the LCED controller. |
| 23:51:38 | amiconn | (2) Flipping the lines itself is also simple, just read from the end decrementing the pointer |
| 23:52:00 | amiconn | (3) BUT the hard thing is flipping the pixels within a line block |
| 23:52:06 | memmem | I think we don't want to use 2 9-bit words per pixel with one color channel split between two words... |
| 23:52:28 | memmem | Just use a 256-byte table. |
| 23:52:46 | memmem | ...for b/w graphics. |
| 23:53:08 | memmem | However, we need 18 bits per pixel unless we find out how to select a different mode. |
| 23:53:16 | amiconn | I wouldn't use a palette mode for high/truecolour displays |
| 23:53:33 | amiconn | I would just use 18 bit mode and use 3 bytes per pixel |
| 23:53:44 | memmem | I was talking about a table for flipping the bits inside a byte for b/w displays. |
| 23:53:57 | stripwax | amiconn - but think of the Plasma-style/color cycling effects you could do in a palettised mode! :-p |
| 23:54:11 | Rick | stripwax: that would be fun :) |
| 23:54:15 | stripwax | memmem right or just do it in hardware.. |
| 23:54:30 | memmem | The iAUDIO firmware uses 3 bytes per pixel in RAM and converts to the format expected by the LCD controller while copying the data to the LCD controller. |
| 23:54:32 | | Quit Harpy (Read error: 110 (Connection timed out)) |
| 23:54:39 | stripwax | memmem wow, that sounds hideous |
| 23:55:09 | amiconn | Maybe the controller does only allow that format, but I doubt it |
| 23:55:24 | Rick | have you identified what lcd it uses? |
| 23:55:53 | amiconn | A bit of conversion is probably necessary anyway for colour lcds |
| 23:56:57 | amiconn | memmem: There are more efficient ways to swap bits than using a table... |
| 23:57:29 | memmem | All the bits (7<->0, 6<->1, ...)? Pray tell me... |
| 23:58:05 | amiconn | You can use a 3-staged shift approach, and that can work on 4 bytes at once, i.e. longwords |
| 23:58:13 | amiconn | I tried it, it work nicely |
| 23:58:29 | memmem | For 8-bit bytes, a table is better. |
