Cowon D2

[crashdebug]

shotofadds: I've tried the touchscreen patch just after you posted it - I think I can confirm what stel said about the jumpy behavior, for me it seems to register a "left" press when repeatedly touching the "up" or "down" area to scroll a long list (the list of games e.g.). Apart from that it works pretty well and is very useful for playing with the plugins.

Even though this is my first post, I've followed this thread from it's beginning - I'd love to contribute to the D2 rockbox porting efforts, but I'm awfully short of free time at the moment. Need to have a good look at the datasheets if I get some time.

[shotofadds]

I think what I'll do is commit the patch as it stands, then at some point in the future "someone" can write a test_touchscreen plugin (or suitably extend the debug menu) so that these issues can be debugged more easily.

The mis-placed "clicks" are annoying, but not really my priority at the moment. Of course everyone is welcome to take a look ;-)

I am done with replacing the button definitions, at least 
It was a little bit more than I thought. I had to think what I'm doing. I mean the mappings should be somewhat usefull 
So a few more plugins are usable, for example blackjack, chessbox, calc and possibly some more. Tested only with sim.
One of the problems is if you control a plugin, the fingers hide some part of the screen

Much appreciated, I'll take a look later today.

This is actually a real problem - try playing brickmania (arkanoid) for example. It certainly adds another element to the gameplay! (Although that specific example could probably more easily be mapped to the physical buttons)

The D2 is never going to be much of a gaming platform...

could this problem not be fixed by shrinking the screen size of the game itself?  Leaving the outside to be used for buttons.  Great work btw!

Hello, I have bought a Cowon D2, 1 year ago...
The original firmware is ok, but there is little bugs, and it's not free, so I tried Rockbox.
It's quite impressive to see it working!
The navigation is somewhat strange, but I hope it'll come with the touchscreen support
Of course, it'll better with sound output and write access to the flash memory, but it's nice to play some games (those which don't need too many buttons) and watch the demos
Unfortunatly I don't think I can help much, but I'll try Rockbox from times to times.

[shotofadds]

Wait a few days and you'll be able to use the touchscreen - then many more of the games will be playable. (Referring to the above posts, of course plugins can be adapted for the touchscreen, but that needs interested people to implement those changes).

[ThibG]

ok, nice!
And will the main UI be adapted for the touchscreen?
I'll read some source code and see if I can understand how it works
One other thing, doom didn't work at all (I've put rockdoom.wad and freedoom as doomf.wad): stuck at "Starting Graphics engine".

Eventually, maybe. Right now you can use the touchscreen for up/down/left/right/select in the menus, but that's just about all.

Not everything can be expected to work right away!

Have troubles applying the d2-touchpad-v2.diff, getting while building the bootloader  :

telechips.c:67 error: too few arguments to function 'button_read_device'
telechips.c:195 error: too few arguments to function 'button_read_device'

normal build is ok

[shotofadds]

The touchpad patch defines HAVE_BUTTON_DATA, which means button_read_device() now takes an output parameter. But I forgot to include the necessary bootloader change in the patch...

Anyway, I've committed that patch to SVN now, so there should be no more trouble with that. I'll commit your keymap changes later, too.

[andiator]

Please wait with commitiing my patch for half an hour, I made some changes to get one or two plugins working

Edit: so I'm done with patch. It's nice to see the plugins working with touchpad 

Sidenode: HOLD-Button doesn't really hold the touchpad, but changes the behaviour of the plugins, so it is not possible to start brickmania in it's menu  if the HOLD-button is on.

(Updated bynaries on FTP (touchpad-stuff), but again, it's only for testing!)

andiator, can you change button mappings for pacbox plugin? Because it's gamescreen is turned 90 degrees CW, so UP should be LEFT, LEFT -DOWN, DOWN - RIGHT and RIGHT - UP. Its hard to play the game with current key mappings

[andiator]

Hi Shady,
of course I can, but I can't commit the source, would new rockbox.zip be ok?
(Ok, rockbox.zip is updated)

[Shady]

of course it'll be ok, andiator, thanks! Gotta play more with the plugins
