Remap buttons?

[GGGGGG]

Is there any easy way to do this?

The reason I'm asking is because my old Sansa e280's scroll wheel broke, so now I can only select songs in the OF anymore, because Rockbox uses the wheel for everything. I left the player alone for a long time and got myself a Fuze instead, but recently I thought I might be able to remap the buttons so that I can select files in Rockbox by using the Play and the Menu key as up and down keys respectively, and in the WPS, use them as VolumeUp and VolumeDown. (Yeah, I know some other keys would have to be remapped as well, but I'm still thinking of the best way to do that.) I wouldn't need the keys in any other section though, as I'd only still use the e280 to listen to music.

So, is it possible, and if so, what do I need to do? Or is there perhaps a custom build that already has the keys mapped in a way similar to this?

Grab the source and edit apps/keymaps/keymap-e200.c, then compile a modified build.

The BUTTON_SCROLL_FWD and BUTTON_SCROLL_BACK instances will probably be need to changed to BUTTON_UP, BUTTON_DOWN, etc.  Though I expect you'll need to experiment to figure out combinations that work well for different screens.

Alright, thank you very much, but how would I go to 'compile' a build?

Great! Thanks!

Is it possible to do simpler mappings without modifying code?

For instance, my Sansa Fuze has no dedicated volume button, so volume adjustment is only accessible on the WPS or in settings.  I'd like a simple, sure fire way to quickly get to the WPS so that I can quickly adjust the volume.

What would be ideal would be to have the 'Home' button always pull up the main menu no matter where you are (never unmapped), except that when in the main menu I'd like to have it pull up the WPS.  That way the WPS is never more than two button presses away.  Is that doable?

Aside from the hotkey option, you have to edit code to change buttons.

Carson Dyle,

You could assign Volume Up and Volume Down to either Left/Right or Up/Down quickscreen slots.

That way, you have a way to quickly access the volume from almost anywhere.

I'm having the exact same problem with my Sansa e280v2, and I must admit I cannot pull the "edit source/compile" option. But I still want to keep using my Sansa, I treat it terribly but it's solid like a rock and never failed me for over 3 years, I broke a philips in less than a week just recently.

Can I assume that you could assign hotkeys offline? If so, how would I do it? Could I make it a combination of two buttons? It would save me a great deal of trouble.

Overlord Nadrian, if I may ask, did you go ahead and compile a custom build? If you did, would you be so kind to share it with me?

I'm not sure you're fully understanding my post...

You don't have to compile a new build at all to achieve this, the manual will tell you all you need to know about the quickscreen and assigning objects to it.

My bad, I totally forgot about quickscreen and wasn't paying attention to the question you were referring to in your previous post. The quick screen suggestion doesnt apply to me anyway, as I am stuck without a scroll wheel to to perform any tasks on player. Even if I was able to assign volume controls to the quickscreen, it wouldn't be much of a help. What I need is to assign the functions of the wheel to two other buttons or button combinations, which seems beyond my skills. Thanks for the help anyway.

edit: I'm actually experimenting with the keymap-e200.c, thanks to "The Simple Guide To Compiling In Linux" it's quite easy to compile a build. What I'm trying to do is kill record function and replace "BUTTON_SCROLL_FWD&BACK" with "BUTTON_REC|BUTTON_DOWN&UP".
My question is, how would I kill all other functions of the Record button? Replacing it with the broken button in the keymap-e200.c doesn't seem to work. What else do I need to do?
Thanks in advance.

Sorry for stealing the thread,Overlord Nadrian. I will try to keep this as short as possible.
OK, I now realize "replacing all" was a stupid idea. I'm looking into the keymap and trying to solve conflicts, it doesn't seem so hard. I gave up some functions such as quickscreen, pitchscreen, scanning through songs, etc. I sorted out some tasks assigned to two buttons like "BUTTON_SELECT" and "BUTTON_RIGHT".  Releasing BUTTON_RIGHT&LEFT from default mapping, I assigned them to ACTION_WPS_VOLUP&DOWN in the WPS like this: BUTTON_RIGHT|BUTTON_REPEAT (which was formerly assign to scanning through songs) so now I can adjust the volume. The player is operational, with the ##Music# being on top and "Power button+right&left" combo, I can open files and switch through albums(folders). However I would like to access the database. Main problem is I can't browse "up & down" in any of the list views. I am stuck on the top. I can't see an option in the keymap either. Where am I doing wrong? What action code or option defines up&down in list views and main menu? Is it independent of the mappings? If you guys take the time to answer please keep in mind that I am not a power user or a native English speaker. Thanks.

Would it be possible to remap the power-on button? Unfortunately the little switch inside the unit broke and I don't have a replacement. (Maybe Frys has one? It is *tiny*!!)

You could remap it inside rockbox, but you'd still need to use it for anything else other then rockbox (like turning on the player).

posfan12, if the power button is broken i think the only way to turn on the player is to connect it to PC. If you turn off auto-shut down you may not even need it. As for remapping buttons, it's not that hard. I'm attaching the original keymap for e200 (open it with any text editor other than notepad, it makes a mess), you might want to take a look, I can share a few tips if you decide to compile your own build.

That being said, I'd like to repeat my question. I pretty much sorted out everything except up and down function in any of the menus(my scroll wheel is broken). Are there action codes for that? I looked through the keymap but cannot find anything useful for me. What I want to do is replace the default tasks assigned UP and DOWN buttons and with those of scroll wheel.
