The current documents are mostly API-oriented. It would be useful to have an overview of all the basic libraries one can (and should) link against (gtk, hildon, osso, gstreamer etc). The doc should explain every library in a few paragraphs:
+
-
* What the library is, what it does, why do you need it
+
-
* What Autoconf/Automake magic is needed to use it
+
-
* Possibly manual compiler switches for compiling and linking

* Various gotchas, initialization order, other funky stuff

What is the preferred way of doing audio on the device? (if ALSA will not get into the device). Think about games with background tracks and audio effects but without sucking all the battery.

It would be useful to have some documentation on compiling and porting this to another device. For example the Nokia 9500, which is a device that is crying out for a Nokia supported linux port... and a spell checker. This could also aid porting to palms and other PDA devices.

'''Comment''': If you want other devices ported in linux, should register these devices in [http://www.handhelds.org/moin/moin.cgi/PortingToOtherHandhelds handhelds.org wiki]. Post specs of the device, open it, take photos of its guts, identify the main chip, secondary chips and e.g. graphics, touchscreen. Ask the manufacturer about the specs. Porting linux into undocumented device will take forever. Hence, getting a maemo device is the way to go.

When explaining source code and/or techniques experience has shown that specifying the OS version and hardware can be very useful for users. Something like: "This procedure has been tested on a Nokia 770 with ITOS 3.2006.49-2" saves users time and energy.
-
I noticed /proc/bootreason - if you say "cat /proc/bootreason" at an xterm shell prompt, you can find out about the circumstances of the last reboot. It seems that if the power adapter was plugged in at boot time, you get "charger". Other options are "pwr_key" (boot via power key) and "sw_rst" (when I ran "/sbin/reboot" from the command line).

This page is for collecting desired documentation into a most wanted list. If you feel documentation is missing for something, please add it here and include a rough list of ideas on what that document should contain.

Contents

[edit] Common tasks and use-cases

Suggestions for APIs or common tasks which need to be documented with code samples, prerequisites, set-up & tear-down. Half way between tutorials and API docs.

Wish-list here - and link to docs when they're created in Documentation#Tasks_and_use-cases.

[edit] General software development

  • How to use the GStreamer *dspsinks

[edit] Audio support

  • How can I play a sound from withing an application?
  • How can I record audio from the microphone?
  • How can I play a backing track without affecting performance, power usage or blocking I/O?

[edit] Debugging aid

  • How to single-step an application on the device?
  • How to debug an application in Scratchbox?
  • How to profile a Maemo application on the device?

[edit] Style guidelines

When explaining source code and/or techniques experience has shown that specifying the OS version and hardware can be very useful for users. Something like: "This procedure has been tested on a Nokia 770 with ITOS 3.2006.49-2" saves users time and energy.

Suggestion: Use tagging & categories to tag documentation as verified with an OS release. --Dave Neary 16:49, 2 March 2010 (UTC)
