Some news on the Fuze's Home button (very related to the recent e200v2 button findings).

The Home button is detectable on DBOP_DIN bit 15, but only if the higher bits in DBOP_DOUT are set.

This means, if the background color/backdrop needs to have at least 128/16 bits (RGB888/RGB565) red color values.
The other thing: GPIOB depends on the background color too.

Setting DBOP_DOUT before reading messes up the display, so this is not an option. We have to find a away to set the bits in DBOP_DOUT without affecting the display. We should also investigate how GPIOB is involved (IIUC it shares wires with DBOP).

Buttons & scrollwheel working great on e200v2 svn now.  Thank you Domonoky!!

ogg playback works fine as long as I leave the wps screen.  If I just stay at wps the music stops after 2-10 secs.  it will restart if I press the play button twice and then stop again unless I leave wps.  MP3 still reboots.

This wasn't possible without your findings about the background color. Thanks a lot for that! It'll also enable the Home button on the Fuze.

May I ask a question? Is the wheel jumpy or unreliable? I've noticed that no post to the button queue is skipped. That causes problems on my Fuze (jumpy wheel, randomly changes direction, wrapping lists (or rather not wrapping if wheel is turned more quickly) not working at all).

edit: Just saw the "if (++wheel_click_count < 2)" line, that seems to be the skipping I talked about. I guess it's fine then.

Chesteta:
On my e200v2 the wheel seems to move very smoothly; it does seem a bit slow; (like i'd like it to accelerate faster if i spin it fast instead of going what seems to be about a constant speed) but that probably can be changed in rockbox settings...

EDIT: also i should note, mp3's play back from the microsd chip (8gb) does work, if you touch the wheel or buttons things stop after ~10 sec.; when first playing an mp3 off the microsd chip, when the back light fades out, the audio does stutter a bit too.  I also noticed that the wheel light seems to 'chirp' on and off as the microsd chip is accessed (I set it to be off by default).  I can try to be more descriptive about the wheel light stuttering if anyone feels it could help :)

EDIT2: the hold button does not work; it can be on hold and the player will still turn on even...

sko:
Buttons working fine on my e200v2 now, but I can confirm I can turn the player on even if the HOLD-switch is set to hold.
Mp3-playback isn´t working at all, rockbox just freezes (my mp3 files have at least 192 kBits).
Ogg works with 128 kBits with staying in the wps and with 160 kBits if I leave the wps, with 256 kBits playback stops after 3 or 4 seconds.
But IIRC & IIUC this depends on the mmu (I read something about in the IRC-Log here). May I ask if there are any news about the mmu?

EDIT: forgot to write: wheel is working fine!
