<adiamas> boo.
|
|
<adiamas> Bagder you around?
|
|
<Bagder> yeps
|
|
<adiamas> wanna test something for me witht he uisim?
|
|
<Bagder> sure
|
|
<adiamas> okay... remove your archos dir under x11
|
|
<adiamas> and then run the sim...
|
|
<adiamas> go to browse
|
|
<adiamas> and try to browse.. tell me what happens
|
|
<Bagder> Segmentation fault (core dumped)
|
|
<Bagder> looks like my fault
|
|
<adiamas> okay.. i have a fix for it.. just no sure you gonna like it.
|
|
<Bagder> x11_opendir() should be fixed
|
|
<adiamas> you need to do a check and make sure your opendir succeeds.. let me get you the line
|
|
<Bagder> right
|
|
<adiamas> want i should toss up my fix?
|
|
<Bagder> I'll fix it
|
|
<adiamas> k
|
|
<Bagder> committed
|
|
<adiamas> i ment to ask.. why arent we using stdlib so we can have NULL
|
|
<adiamas> or define our own NULL
|
|
<adiamas> ?
|
|
<Bagder> we should
|
|
<Bagder> just me being lazy

|
|
<Linus> Moo!
|
|
<Bagder> boo
|
|
<Bagder> you digging mp3s now? ;-)
|
|
<Linus> Well, almost
|
|
<Linus> I have some issues with the MP3 bit swapping performancs , but it rocks!
|
|
<Bagder> I can imagine that
|
|
<Linus> I don't like having to bitswap every f**king byte of an MP3 song
|
|
<Linus> It takes time
|
|
<Bagder> no shit? ;-)
|
|
<Bagder> perhaps we can make second read() or something that bitswaps right away when reading
|
|
<Bagder> but perhaps it makes no diff
|
|
<Linus> We should. Or even at ATA level, so we don't even have to store the unswapped bytes.
|
|
<Bagder> yes, that's my thought
|
|
<Bagder> an ata_read_shift() function
|
|
<Linus> And prehaps swap at a word level. That saves us half the time.
|
|
<Linus> ...with a 64K table... :-(
|
|
<Bagder> yeah
|
|
<Bagder> but we can generate the table in runtime at least
|
|
<Linus> Yup
|
|
<Bagder> do you know if the recorder will need this swapping too?
|
|
<Linus> I don't think so. It has a parallel interface
|
|
<Bagder> ah, right
|
|
<Linus> Still, the loop I am using today is far from optimal. If we hand-assemble the bitswap loop it shouldn't take much time.
|
|
<Bagder> have you been able to load new parts of the mp3 while one part is playing?
|
|
<Linus> I haven't tried yet. That's my project for tuday.
|
|
<Bagder> you rock
|
|
<Linus> I do my best
|
|
<Linus> Luckily, this is what I'm best at :-)
|
|
<Bagder> :-)
|
|
<Linus> It took me some time to discover that the FAT driver didn't swap the words in the FAT...
|
|
<Linus> And not that much time to doscover that the SWAB32 macro was braindead.
|
|
<PsycoXul> btw, i had a thought the other day.. how does the firmware on the HD effect the charging and how/when it claims to be charged
|
|
<Linus> I don't know. I guess it measures the voltage using the A/D converter.
|
|
<Linus> But it must be somewhat complicated to get a good A/D reference voltage...
|
|
<Linus> Someone with good knowledge of electronics will have to look into this
|
|
<adiamas> icon wise.. i was thinking.. the char maps we have on the website... should those all be mapped?
|
|
<Linus> In the simulator?
|
|
<Bagder> we should get the player ones in for the simulator to look more like a Player
|
|
<adiamas> umm.. by 'player' you mean recorder icons?
|
|
<Bagder> no
|
|
<Bagder> we simulate the player
|
|
<Bagder> but we do that using our own defined charset
|
|
<Bagder> which happens to be the same as we use on the Recorder
|
|
<adiamas> okay, so i should do the player icons first?
|
|
--> wavey (~wavey@dlan1431.dircon.co.uk) has joined #rockbox
|
|
<Bagder> they are the only ones we more or less need to make a good simulator, yes
|
|
<adiamas> okay...
|
|
<Bagder> the recorder-ones aren't needed, since the Recorder doesn't have them "built-in"
|
|
<Bagder> although some of them might be useful anyway
|
|
<Bagder> it looks as if they made the battery meter using chars...
|
|
<Linus> hi wavey
|
|
<adiamas> um.. okay. now im confused again...
|
|
<adiamas> 1. what do you mean by 'built-in'
|
|
<Bagder> the Player has those characters built-in into the LCD stuff, we can't change them
|
|
<adiamas> okay.. then how do we reference them?
|
|
<Linus> Bagder: The battery icon is not character based. It's specially made on the LCD.
|
|
<Linus> Like the USB icon and a load of others
|
|
<Bagder> adiamas: we send ascii strings to the LCD
|
|
<Bagder> Linus: oh, ok, but there are chartacters looking very much as if made for that purpose
|
|
<Linus> ah. in the recorder?
|
|
<Bagder> Linus: yes
|
|
<Linus> IC. I'm a player guy. :-)
|
|
* adiamas is way lost
|
|
<adiamas> have we worke don those 'char strings' at all?
|
|
<Bagder> adiamas: check out lcd_puts() for the Player LCD
|
|
<Bagder> we just send a plain string to that LCD
|
|
<Bagder> it isn't graphical at all
|
|
* adiamas shrugs
|
|
<Bagder> they player LCD is simply two lines with 11 letters on each
|
|
<adiamas> nod
|
|
<adiamas> i just don' get how char strings give you the output.
|
|
<adiamas> namely, how we know what string does what
|
|
<Bagder> we pass a string like "abcde"
|
|
* adiamas feels progressively dumber
|
|
<Bagder> the LCD shows that on screen
|
|
<adiamas> well that i get...
|
|
<adiamas> what about file icons
|
|
<adiamas> or battery indicators
|
|
<Bagder> eeh
|
|
<Bagder> there are some fixed "icons" on the LCD
|
|
<PsycoXul> heh
|
|
<PsycoXul> adiamas: those are pre-defined in the LCD
|
|
<PsycoXul> adiamas: we only turn them on or off
|
|
<adiamas> okay.. then with all of this.. will we be defining our own icons at all...
|
|
<adiamas> and if not, why did we start to for the recorder?
|
|
<Bagder> the Recorder supports them very well
|
|
<PsycoXul> icons are just whats defined in the LCD already for the player
|
|
<PsycoXul> then we've got CGROM which contains all char set mapped out already, and CGRAM where we can draw 8 of our own chars
|
|
<PsycoXul> for display on the 2 lines
|
|
<Bagder> ... but we don't simulate those Player icons at all yet
|
|
<adiamas> okay.. so for player everything is done...
|
|
<adiamas> now.. what about the recorder?
|
|
<PsycoXul> for the player everything is done on target, but not much simulated
|
|
<Bagder> we should introduce an API for the Player LCD "icons"
|
|
--> calpefrosch (~calpefros@62.52.174.30) has joined #rockbox
|
|
<Bagder> adiamas: actually, I think we should think through how we want the icons and images present on the recorder screen
|
|
<adiamas> presented you mean?
|
|
<Bagder> adiamas: like how the built-in sw always have a number of icons on the screen, whatever screen we view
|
|
<adiamas> well, thats going to be a factor of how we work the menuing
|
|
<Bagder> yes
|
|
<Bagder> hey calpefrosch
|
|
<adiamas> another factor to consider is, if we are going to 'zoom' in on items... ie: increase font size, for the user..
|
|
<adiamas> what happens to the icons then
|
|
<Bagder> right
|
|
<Bagder> there are a few "usability issues" to sort out

<wavey> howdy :)
|
|
<adiamas> we now have the file on that was there, plus folder, open box, filled box, the triangle selector and some other stuff...
|
|
<Linus> Bagder: I looked at their FTP. Loads of newlib releases. Where are you looking?
|
|
<Bagder> "Source snapshots are available as gzipped tar files via anonymous FTP from the newlib ftp directory."
|
|
<Bagder> yes there're there
|
|
<Linus> Well, that is not entirely true. The have release archives as well.
|
|
<Bagder> the CVS still doesn't work ;-)
|
|
<Bagder> and their ftp server is full
|
|
<Linus> Actually, that is only what they have. They don't have snapshots. :-)
|
|
<Linus> How large is your mailbox?
|
|
<Bagder> they don't actually say that they are releases anywhere
|
|
<Bagder> therefor, I assumed they are the snapshots they mentioned

<Linus> ftp://sources.redhat.com/pub/newlib/newlib-1.10.0.tar.gz

|
<Zagor> (in the simulator, I mean)
|
|
<Bagder> I was hoping we'd get the the one the other guy was working on... but...
|
|
<Bagder> Zagor: edit the Makefile to build a Player simulator
|
|
<Zagor> I did. but nothing happens when I start it
|
|
<Bagder> no window with silly text in it?
|
|
<Zagor> no, just empty. I only redefined $(DISPLAY), but that should be enough right?
|
|
<Bagder> yes
|
|
<Bagder> lemme see
|
|
<Zagor> umm, wai
|
|
<Zagor> t
|
|
<Zagor> it's the x11/Makefile I need to change, nothing else?
|
|
<Bagder> yes
|
|
<Bagder> make clean and make
|
|
<Zagor> yup
|
|
<Bagder> I get text in my window
|
|
<Zagor> I don't
|
|
<Bagder> move it then, or put a window over it a while or something to get an event
|
|
<Zagor> ahh
|
|
<Zagor> now I got the text
|
|
<Bagder> :-)
|
|
<Bagder> I've seen that happen before, I'm not sure why this happens though
|
|
<Bagder> X11 magic stuff
|
|
<Zagor> ok, I'll add player support to tree.c
|
|
<Bagder> goodie
|
|
<Bagder> "<wannabeuihacker> I added the menu functions and got a menu system for the player"
|
|
<Zagor> ok, good
|
|
<Bagder> but I never got any
|
|
<Zagor> ok
|
|
<Zagor> hmm, maybe we should have a lcd_setfont() call instead of a font parameter to lcd_puts(). as it is now, I have to #ifdef all puts() calls just because of this
|
|
<Bagder> the coordinates are different too
|
|
<Zagor> uh, right. I'm a fool :)
|
|
<Bagder> :-)
|
|
<Bagder> setfont() might be good anyway
|
|
<Zagor> the bad thing is it introduces "state information"
|
|
<Bagder> yes, but it would reduce a large amount of passed zeroes...

|
|
<Zagor> hmmm, idea: we make a lcd_setfont() and a lcd_setmargins() call. then lcd_puts() can use x,y "char position" for both player and recorder
|
|
--> alkorr (alkorr@srs02m-7-99.n.club-internet.fr) has joined #rockbox
|
|
<Zagor> that would make much code identical

|
|
<Bagder> would even make "zooming" work
|
|
<Zagor> yeah
|
|
<Bagder> when setfont()ing a larger font
|
|
<Zagor> good point
|
|
<Zagor> we should have both "charpos" and "bitpos" calls. what do we call the "bitpos" call? putsxy is not very obvious...

<adi|home> linus you around?
|
|
<Linus> Now I am
|
|
<adi|home> k...
|
|
<adi|home> umm.. not sure, but you may want to talk with linuxstb
|
|
<adi|home> <linuxstb> I've started implementing a mpeg playing thread in the x11 simulator
|
|
<adi|home> <linuxstb> Someone should try and mirror my development in the win32 simulator!
|
|
<adi|home> <calpefrosch> yes, I have seen some code. Do you use the libmad code ?
|
|
<adi|home> <linuxstb> Yes. I have also started to use pthreads - I'm not sure if that is good or bad
|
|
<adi|home> he wants to add the libmad to the source tree, but hasn't gotten an answer from anyone...
|
|
<adi|home> he says its appx 900k
|
|
<Linus> Well. What is this libmad thing?
|
|
<Linus> Gotta sleep. Night!
