Sansa Fuze+

[evemir]

Is it be possible to disable click sound when keys are locked? This is pain in the *** because the touchpad is so sensible that it activates even inside a pocket...

[metaphys]

oups right I'm going a bit too quick on this one!

click sound should'nt be activated by default

On a (vaguely) similar note to evemir's post, I find that, due to the high sensitivity of the touchpad on the fuze+, it does indeed register touch inside one's pocket fairly consistently, and that does not do delightful things to its battery life, thanks to the activation of the backlight repeatedly, often on intervals shorter than the timeout.

My current imperfect workaround is just to have a very short timeout and a low brightness setting, but this can be inconvenient in its own right when I'm interested in doing something in brighter environments and/or taking my time perusing music.

Is there any other workaround? Though I don't recall any such function, is there a way to set a separate time-out and/or brightness when the keys are locked? Or perhaps the unit should simply not respond to anything but the lock function, even in terms of the backlight?

I'm not opposed to poking at the source, but as I'm utterly unfamiliar with it and am not much of a coder, I have doubts as to my ability to accomplish anything....so I figured I might as well ask first.

[metaphys]

hum!!  Very good point! I have no Idea but that definitively worth a try! I too busy with the manual/plugin keymaps right now but I find the idea really interressant

[Eridyne]

Tis just a thought - I know it's more of a general feature, but out of all the players I've used rockbox on, this one alone has issues with burning up way too much battery life with constantly detecting touches and turning the screen on.

I rather think it's quite low priority, though. Would be convenient, but isn't a serious issue.

I am a bit surprized by what you say since the fuze+ has a capacitive touchpad so it's not sensitive to pressure. The only way I could think about false activation in a pocket would be that it detect your skin.
Unfortunately I can't think of a perfect solution. Making the device inactive while locked is not an option, reducing the touchpad sensitivity while locked seem feasible although I'm unaware of such a mechanism in rockbox so it would specific to this target.

The battery life is something complicated, it's not only related to backlight and touchpad. Furthermore, we are not that bad with approximately 16h of playback. It's just that there is still some work to do to reduce power consumption when possible but that requires time.

[Eridyne]

I was a bit surprised as well that it activated, as I'm aware it's not sensitive to pressure. It does seem, however, to be sensitive enough to detect skin through any thin material - including your average jeans pocket or thin knit gloves. It wouldn't be a problem if I had other pockets, or put the fuze in a jacket pocket, I suppose, but it seems to always get dropped in my jeans pocket, out of habit, and I don't always have a jacket on.
Reducing the sensitivity when locked would be a good idea, I think, better than any of my suggestions, but I imagine it would be quite a pain to implement.

Battery life is always complicated, I agree. I was merely pointing out, in my earlier post, that having the backlight on much of the time doesn't help the battery life, not trying to imply that it was the primary deciding factor.

EDIT: Out of sheer curiosity, just tried using the touchpad with a bit of my t-shirt wrapped around my finger. Works...surprisingly well.

Meta: I can now say I definitely do not like 13 as the sensi value it fells way to sensitive, mostly I've been using 10 sometimes 11 so I for one would like a permanent setting for sensi somehow (if that's possible).

[metaphys]

possible certainly but for the moment I have to much to do with other stuff (keymaps, manuals...) those are pretty easy stuff to  do but take a lot of time, and as no one is helping well... this is going to take a lot of time...

[alienkid10]

No problem simply reporting in like you wanted. Thank you both for doing this! Unfortunately I don't have time to learn to help with the manual since I'm wrapped up in my school and Boy Scout stuff.
Thanks to you both again!

Hey all
I'd like to contribute, but I'm not sure about how much detail I need to provide.
I got hold of a Fuze+ 8gb and rockboxed it, but it's extremely buggy.
(I'm not moaning, I want to help if I can)

Among the issues found are:

• Recording doesn't work (not implemented, known)
• FM Radio doesn't work (Debug reports no hardware or depending on RB build. Image is from current setup) Freezes when attempting to start the radio
• MicroSD card doesn't show up in Windows, but does show up in Linux regardless of settings related to hiding internal drive and HID mode. (Formatted as FAT16)
• Garbage on music playback (sometimes) Restart usually fixes it, haven't been able to pinpoint steps to reproduce. Music plays up to 50% faster when this happens, so it sounds like samples are being missed. Looks as though buffer is full when this happens, but don't have confirmation. Will create recording upon request.
• MPEG Player says "Cannot create buffering thread" upon attempt to playback video, including known supported files

Will update when I have more specific details on other problems.

Question: How difficult would it be to change the mouse HID mode to use the touchpad as an actual touchpad? Support for gestures is already implemented in the firmware.
All that needs to be done is for the relative cursor position to change depending on position on touchpad as opposed to button presses, or at least my limited knowledge leads me to think...

RE touchpad sensitivity, the touchpad works even with the cover which comes with the device. I can even make it work with my finger 1 or 2mm away.

Is the Fuze+ destined to be amongst the stable builds, or was buying one instead of the Clip Zip a stupid decision?

Hello,

Recording doesn't work
FM Radio doesn't work

Those are not bug - just not fully implemented yet.

Please do read the port's page on the avancement

MicroSD card doesn't show up in Windows

If you want to help on this go there this has been reported: http://www.rockbox.org/tracker/task/12458

MPEG Player says "Cannot create buffering thread" upon attempt to playback video, including known supported files

This has already been reported in this thread but it would be good to have a bug report as a reminder - feel free to open one there: http://www.rockbox.org/tracker/index.php (don't forget the field player)

this has been reported by rarog, I do also experience it but this is very rare on my device (pehraps because I use special codec) Feel free to add a new bug report on Flyspray, I don't think that there is already one.

For what I know (not much  ) it is a little more complicated but some work has started in this direction in order to have a proper way to test/debug gesture

All player are destined to be stable. I t just depend on the work you want to do on it...

FM RADIO
I have read the port status page, but I assumed that the FM radio simply wouldn't tune, not that it would freeze the player.

MOUNTING IN WINDOWS
The MicroSD card issue I think is different to the one in 12458. It is Windows specific and occurs both from the bootloader as well as from within Rockbox. Accessing the SD card is only possible if you hide the internal drive, it won't see both otherwise.
Both the internal memory as well as the card show up using my Clip+ on the same computer.

Task opened here

GARBAGE AUDIO
Will look into this and open a task if necessary. Any suggestions on technical debug info to look for while experiencing this behaviour?

HID
On the HWInfo screen, one of the pages shows you exactly where your finger is on the touchpad and recognises gestures. So the information is already there, it's just a case of interpreting it correctly and sending it to a computer.

Code: [Select]

while (finger down)
cursorPos = value relative to measured coords upon finger down

That's how it works in my head, reality might differ...

This can't be stable soon enough

Yes but actually hid implementation works with button. So the way it work's now is: touchpad driver convert absolut value into virtual button, button are passed to hid. hid control mouse. For what you are talking about to work, hid need to be rewrited... and this is clearly something not that urgent because the main point of hid is for device with remote control: you plug your device and use remote to control the computer. So except to piss off your friends saying: "hey look what my rockboxed device can do!"  (mandatory! ) I can't see no high priority in this.

MOUNTING IN WINDOWS

If you think this is something different then please open a new bug report

no idea, pamaury is doing the core implementation on the fuze+ you might find people on the IRC that could help

[metaphys]

new change today:
- pamaury add a thread that should solves the mpeg-plugin (videos)
- he also commited 2 patchs I made:  1) consistent and usuable keymaps on all plugin game
                                                           2) correct a little bug that was leading volume up key to be interpreted as power key
