Sansa Fuze+

[[Saint]]

<snip>...I had the feeling it was finished and close to being issued 2 months ago, but nothing has happened since then...<snip>

Fact of the matter is, as I'm sure you are at least partially aware, the developers work on what they want to work on when they want to work on it. The nature of this project allows you to contribute yourself if you feel that development is going slower than you would like it to.

Please don't read this as: "If you don't like it, go and do it yourself", but please do read it as "The maintainers of new ports are more often than not working largely alone, doing a job that has the potential to consume many hundreds of man hours, and those that would like to see a particular feature implemented or a particular bug squashed should seriously consider taking a crash course in C, setting up a development environment, checking out the source, and contributing to those areas themselves."

I am sorry if it seemed that I am complaining. 

I am very happy that someone took the tedious task to make Fuze+ usable when SanDisk didn't do the job. It is just perfect, as it is now.

I was just curious what happened, as it seemed to me, that it was prepared for release. I can live without recording ability, if it is not implemented at all...

any of you notice strange charging behaviour ?
what i mean is i plug in charge mode starts.. i leave it for a while
and when i come back after a while it stopped and says connected.
and when i pull out the cord and check the battery level its only partly charged.

I've noticed this, too. My player never charges past 96% or so. This behavior started appearing after Pamaury did some battery calibration (then I had problems with internal storage). The OF show 100%, so perhaps the battery need a little more calibration. I can't say about your player, though.

Also, you should try getting a portable battery charger. I have one from Duracell, and I tend to bring it whenever I think I will be away from my computer and will be listening to a lot of music. It's a bit more of a pain, but its cheaper than buying a new player. You should be able to get one form Amazon.

notice the first sentence you quoted ?
and buddy we have been talking back and forth over at Sansa long before i came over here
so you already know my name lol
I brought this up because like everyone else is saying normal behaviour is normal
and what i'm seeing is *obviously NOT.
a) The charging behaviour is weird. (It doesn't get fully charged)
b) The charge doesn't last.. (even when device is off / as reported many times at Sansa forums)

so YES it's related.. think about it
or should i explain ?

Not to seem rude, but please don't. At least not here.

Once again, this is a SOFTWARE DEVOLOPEMENT THREAD. There's a hardware section of this forum you can use if you wish. If  you wish to permanently upgrade your battery, there's also a "Repairing and Upgrading Rockbox capable Players" thread with people who could help you with that. Otherwise, I guess you're out of luck. :'(

Hi all,
to reply to the few complains about battery life, I would like to state again that 1) the battery life will naturally decrease over time, this is not related to rockbox 2) rockbox on the fuze+ still lacks some power optimisations with explains the lesser lasting battery but we do our best to improve this.

On the good side, I would like to point out that I (hopefully) solved the audio pop on startup in the current HEAD so I would greatly appreciate feedback on this. I also made a RMAA test to compare the fuze+ OF with rockbox and the results can be seen here: http://amaury.pouly.free.fr/Images/Comparison.htm. The results are encouraging but there is a lot of distortion compared to the OF so I still need to improve this.

[RipCurl]

hmm, THD and  intermodulation distortion seem to be A LOT worse than OF and Intel Onboard Soundcard(?).... looks like the rockboxed fuze+ sounds (at current state of development) not as good as the OF fuze+...

E: maybe some eq involved?

E: now the audio pop is lot more gentle/almost unhearable. the white noise before playing the first track after booting is gone also....

Hi Pamaury,
thanks a lot for your work on Sansa Fuze+. OF was almost unusable with more music loaded in....

Thanks for audio quality comparison. Are the high values of low frequency "noise" related to a problem that I started discuss in this thread?
http://forums.rockbox.org/index.php/topic,41608.0.html

I noticed it first in Fuze+ (but it seems to me that it was not always like that....) and after RockBoxing iRiver H120 also in iRiver, which was quite surprise for me. In iRiver, there is no "noise", if optical digital output is used. So I guess, it must be related to D/A conversion in both devices.

I hope, it helps.

noise beep on startup much better here too

EDIT:
What about RDS I'am on the impression that it is working much better now. Wiki port's page still mention problem should I correct it?

[fsclavo]

Thanks again for your work pamaury!
The startup pop sound is almost unhearable.

[pamaury]

Yes the RDS is working much better because we relaxed and improved the parsing a few months ago.
@metaphys: go ahead and fix the wiki

[metaphys]

ok wiki corrected.

what about my touchpad sensitivity patch?

I don't know if you guy are still having issue with clock, but you might want to have a lock here:

[pamaury]

I recall to everyone that this thread is *not* meant to fix problems, it's about development only. If you have problems with your device, please first have a look first on the wiki  http://www.rockbox.org/wiki/SansaFuzePlusPort and then  ask on IRC http://www.rockbox.org/irc/. There is known problem about the clock/date which might stop, please see here http://forums.rockbox.org/index.php/topic,41766.0.html and there is some noise while playing sound which is still to be fixed. It is also known that keypress while backlight is off behave strangely.

[pamaury]

I changed some audio code to try to improve the audio quality, here is the result: http://amaury.pouly.free.fr/Images/Comparison3.htm. As one can see, with a correct bias this is much better but the frequency response suffered a bit.

[xpmule]

Not sure i can wrap my head around what you said pamaury lol
did you commit your new changes ?

I looked in this topic because i have been having strange key press behavior for a while
and i have been randomly dropping by and updating to newer builds.. so i dunno
Hard to explain but the navigation is just going to hell and any problem i can think of has been happening
some times stuck key presses sometimes skipping drastically through menus etc
So i cam here to see if anyone was seeing the same.. doesn't look like it

I think i'll try and reformat and reset all settings etc and see if that helps ad maybe clean it too
although its already pretty clean (touchpad area) it does get finger prints on it though cause well you press it lol

Thanks for your continued efforts
Reading the recent activity occasionally i see your coding skills dwarfs mine so much i doubt there would
be much point in trying to contribute anything with you guys lol
You got some serious skills and the technical understanding of some advanced stuff for sure !

Last minute question..
Is there a future goal to get Rockbox to charge the device or should we just get used to booting orig firmware for that ?

Thanks also to the other contributors too for example J.Gordon
He's been working endlessly over time to improve a lot such as GUI related stuff i noticed. (experiments / fixs etc)

Not a lot i can do to support the project but its of such high quality that i have a perm interest..
Even if i don't post comments i'm happy to see the recent activity page HAS recent activity. lol
Rockbox is a project in its own league and deserves my butt kissing lol
