YH8xx,YH9xx: Keymap improvement

2015-11-15T22:46:39+00:00

The main "innovation" in this patch are two "virtual buttons"
for the record switch on YH92x targets. When the switch state
changes, a single BUTTON_REC_SW_ON or .._OFF button event will
be generated. Thus keymap code can react on switching, but
not on the actual state of the switch.

Wherever sensible, the following user scheme is applied:
- use PLAY as confirm button
- use REW button or Long REW to exit
- use REC (YH820) or FFWD (YH92X) as modifier key for button combos

Enhancement of the metronome plugin:

2015-02-03T21:41:40+00:00

- square sine tick and tock sounds (more annoying, more useful;-)
- optical indication of tics on display
- unification of mode of operation for SWCODEC and HWCODEC (tested on simulator)
  Both playback and display drawing happen in main loop, always.
- operating in two modes now:
-- 1. classic dumb metronome
--- active when openened as application without file to open
--- the usual functionality with tapping and bpm change
--- controls indicated on display
-- 2. track mode with programmable series of parts
--- active when started as viewer for a .tempo file
--- differing meters (4/4, 3/4, 6/8, etc.)
--- patterns (tick/tock/silence on each beat)
--- smooth tempo changes in those tracks

This version had lots of testing regarding metronome accuracy,
resulting in the realization that PLL A and PLL B differ
on the Clip+, causing drift. There is still drift when the timer
intervall is too small, so I settled on 2 ms as compromise.

This is the final version, after adding documentation and extensive
help from Sebastian Leonhardt testing it on slower hardware (YH820),
where it works up to 650 actual bpm with display indication.

Latest change: Documentation nitpicks.

Separate keymaps for YH-820 and YH-920/925

2014-05-23T22:50:11+00:00

Although both players basically have the same keys, the
differences in the layout is rather big, so I think both
deserve their own keymaps.

(On the yh820 the FFWD/PLAY/REW buttons are located above the
direction keys, on the yh920 at the side of the player.
Furthermore the yh920/925 has a REC switch, whereas
yh820 has a push button.)

Tweak paramters of mp3_play_data and callback.

2012-03-04T19:50:47+00:00

Use generic void * and size_t and make mp3_play_data and its callback
agree on types. Use mp3_play_callback_t instead of prototyping
right in the function call (so it's not so messy to look at). Change
doesn't appear to require plugin API version increment.

Revise the PCM callback system after adding multichannel audio.

2012-03-03T06:23:38+00:00

Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

plugins: another round of making local things static and adding missing #includes

2011-12-28T11:32:13+00:00

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31453 a1c6a512-1295-4272-9138-f99709370657

Changed the FOR_NB_SCREENS macro to always be a for loop that declares its own loop variable. This removes the need to declare this variable in the outer scope.

Second try: Introduce plugin_crt0.c that every plugin links.

2010-08-24T14:30:46+00:00

It handles exit() properly, calling the handler also when the plugin returns
normally (also make exit() more standard compliant while at it).
It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore.

To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it.
In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit().

In future plugin_crt0.c could also handle clearing bss, initializing iram and more.
