____________________________________________________________
- WiiYourself! - native C++ Wiimote library v1.15
(c) gl.tter 2007-10 - http://gl.tter.org
____________________________________________________________
History:
What's new since 1.01a? - Main Features (see ReadMe & full history for details)
+ Balance Board support with automatic offset removal.
+ Seemingly solid MotionPlus support.
+ Library no longer includes project files - just add wiimote.cpp &
header to your project (avoids all build-settings releated issues)
+ better MinGW support: (thanks Elmo)
adds functional _ASSERT/TRACE/WARN/DEEP_TRACE macros
non-MSYS dependent build option via 'make_mingw.bat'.
Demo builds & works under MinGW.
+ new Python wrapper (by Robert Xiao, see 'Python' folder for details)
+ library now compiles on Borland (thanks Griff - demo not tested).
+ many fixes, connections should be more reliable.
+ join my mailing list to give feedback, share ideas & stay informed:
http://gl.tter.org/mailman/listinfo/wiiyourself_gl.tter.org
1.15 Final:
+ fixed MotionPlus detection on stacks that require HID writes!
+ Balance Board corner weight values have been quartered (.Total remains
unchanged). The non-raw corner weight incorrectly reported 4x their
real value.
+ Wiimote calibration info is more reliably received (it may not have
arrived in many instances)
+ exposed a partially-unique device ID (wiimote::UniqueID). This 64bit
number is set during the Connect() call, and is derived from the
device-specific calibration values. It's therefore not guaranteed to
be truly unique (several devices may conceivably hold the same calibration
values). However in practice it is likely to be unique between a
few wiimotes, so it can be used to eg. assign a particular wiimote to the
same player every time.
+ internal: made the HID report output queue fixed-size to remove any
glitches from frequent dynamic memory allocation (thanks
Steve). The old STL-queue based code can still be reenabled
by defining USE_DYNAMIC_HIDQUEUE.
1.15 RC2:
+ added Python wrapper by Robert Xiao - you can now use WiiYourself! with
Python! (thanks Robert)
+ hopefully fixed MotionPlus connection problems! (send report to my
mailing list)
+ added virtual event-change notifier to the wiimote object (thanks Robert
Xio) - works the same as external callbacks. To use, derive your own
class from the wiimote object and override ChangedNotifier()
+ changed the way callbacks work:
in previous versions, it was OK to access the wiimote object's state
from callbacks. This required an internal RefreshState() call just
before the callback function is executed - but this could then change
the internal state unexpectedly, so values could change in polling
loops even between the app's own RefreshState() calls.
to correct this, the callback functions now get a read-only copy
of the newest state passed in, you should only access this copy as
state in the wiimote object is likely out-of-date.
In short, the wiimote object's exposed state is now _only_ refreshed
by the application, not by callbacks.
(this also solved Motion+ connection and disabling failures).
+ added new change event 'CONNECTED'
the demo previously used callbacks to set most of its report types, but
it also set them once shortly after connecting the wiimote, and this could
cause it to set the wrong one, breaking extension data. Instead it now
uses the CONNECTED event in the callback. It's best to only set these
in one place.
1.15 RC:
+ fixed missing Balance Board calibration values for the 34kg category
(thanks Benjamin Lassort).
+ fixed Wiimote disconnecting in certain scenarios (ReportType wasn't
initialised, and this could sometimes be sent to the 'mote, causing
it to disconnect - thanks Robert Xiao).
+ minor changes to support Robert Xiao's WiiYourself! Python Wrapper!
(next release).
1.14 BETA:
- added new state & callback event: bBatteryDrained / BATTERY_DRAINED
this is sent went the wiimote signals that the batteries are nearly
empty.
- added MotionPlus extension events (ie. for extensions plugged into it):
MOTIONPLUS_EXTENSION_CONNECTED
MOTIONPLUS_EXTENSION_DISCONNECTED
wiimote::MotionPlusHasExtension()
wiimote::DisableMotionPlus()
wiimote::EnableMotionPlus()
(apps can now decide if they want to disable the MotionPlus to read the
extension instead, see demo for an example)
** however **, MotionPlus disabling isn't reliable at the moment (it
rarely works), and so extension connected to an already enabled plus
rarely are activated. Could use some help on this one.
1.13 BETA:
+ ** BALANCE BOARDS no longer require setting a report type! **
there is only one type for it, and this is now set automatically.
+ 'At Rest' offset removal added (currently only for Balance Boards).
this reads the current analogue sensor values after a Connect() call,
and then subtracts them from future values, to remove any unwanted
offsets (currently ~ +- 0-2.5kg with Balance Boards). 'raw' values
are not affected.
If the device was not at rest during Connect(), then the app can
remove the current offsets manually via CalibrateAtRest().
+ ** PRELIMINARY MOTION PLUS SUPPORT! **
Motion Plus does not report itself until queried, so it's currently
queried every second. If detected, it is activated and is reported
like any other extension. Note that extensions plugged into the
MotionPlus itself can't currently be used at the same time (it's not
known if this is even possible). Right now you need to unplug the
MotionPlus to use another extension (I will add some way to toggle
the MotionPlus so that another extensions becomes available again)
in the next release.
According to this interview with the MotionPlus designers
there are two gyro sensitivity modes, but this has not been reverse
engineered yet. Also I'm not 100% certain of the correctness of the
values (although they seem right), or their actual scale (ie. how many
degrees rotations per second do the float values actually represent)?
+ the Demo has been updated for both devices.
+ ReadMe has been updated with new relevant info.
1.12 BETA:
+ ** REMOVED ALL LIBRARY PROJECTS **
instead just add wiimote.cpp to your application and include the header
as before (this removes all build/project related-problems, like matching
the runtime/Unicode settings etc).
+ Balance Board is now working (thanks to Akihiko's donation of a board!)
+ added wiimote::IsBalanceBoard() (Balance Boards are detected as wiimotes
with a permanent BALANCE_BOARD extension).
NOTE: Balance Boards require the IN_BUTTONS_BALANCE_BOARD report type
(see demo).
+ changed some of the wiimote_state extension enums to ID a wider variety.
+ no more invalid acceleration values from devices that don't support it.
+ fixed some project settings.
1.11 BETA:
+ new way to detect extensions (supposedly works on all of them, including
wireless Nunchuks) - only tested on stock Nunchuk.
+ longer sleep after SetReportType (may help data not being reported).
1.1 BETA:
+ beta Balance Board support!
+ better MinGW support: (thanks Elmo)
adds functional _ASSERT/TRACE/WARN/DEEP_TRACE macros
non-MSYS dependent build option via 'make_mingw.bat'.
Demo builds & works under MinGW.
+ directory reorganisation:
- Each compiler has own project dir (VC2005/VC2005/MinGW),
and equivialent lib/ sudir.
+ now ships with working VC2005 SP1 / VC2008 / MinGW libraries
(and MinGW DLL).
+ library now compiles on Borland (thanks Griff) - demo may not.
1.01a: (1.01 had incorrect version defines)
+ extensions now work when already connected before Connect(),
& also when an EXT SetReportType() is used initially.
+ ** renamed wiimote_state::IR::dot::bVisible to 'bVisible'. **
+ Disconnect() now waits for its threads to exit.
+ made TRACE/WARN macros VC2005+ specific (as earlier VC versions don't
support variable arg macros).
+ corrected wiimote.h Connect() comments (wiimote selection is 1-based,
not 0-based)
1.00:
+ ** major bug fix, write buffer was abused. ** might have caused various
problems.
+ ** added delay to EnableIR(), fixed IR init problems for those that
had them (thanks Cameron) **. if you had to use your own delays
to get things to work, try removing them now.
+ wiimote_state::classic_controller::buttons::TriggerL() / R were reversed
(thanks Vico).
+ patch & Makefile for MSYS / MinGW (thanks Dario).
+ updated ReadMe.
0.99b:
+ added support for the Guitar Hero controller (thanks Morgan).
It's just a Classic Controller with a different ID and is read the same,
but can be differentiated via wiimote_state::extension_type::CLASSIC_GUITAR.
0.96b:
+ fix ClassicButtonNameFromBit[]
+ fix WIIYOURSELF_VERSION_MINOR2
0.95b:
+ Classic Controller button fixes (thanks Farshid).
+ sightly longer Sleep() in Reset() - hopefully fixes some reports of
wiimote acceleration values not working.
0.94b:
+ deadzones weren't working.
0.93b:
+ ** compiled libs are now stored in /libs **
+ ** up to 4 dots are now available in every IR mode **
+ some 'state_change_flags' weren't quite generated correctly.
- removed 'wiimote_state::polling' flags (redundant, flags are already
returned via RefreshState()).
+ various internal improvements
0.92b:
** Polling changes **
- now need to call RefreshState() once before each polling pass (see
header comments & demo). this was done to synchronise the threaded
state updates, so that data integrity is guaranteed.
** Callback changes **
- combined 'wiimote_state_changed' and 'extension_state_changed' flags
into 'state_change_flags
- removed 'ExtensionChangedCallback' (only a single callback is used now)
- added 'CallbackTriggerFlags' to minimize callback overhead
(see header comments & demo)
+ added Reset() (see header comments)
+ button mask TRIGGER is now _B
Demo: removed 'wiimote2' line (debug leftover)
0.82b:
** code/demo failed pre-XP (HID writes require XP+). code now detects
HID write support dynamically. **
+ tidied code & surpressed redundant warning (or just enable C++ exceptions).
+ Improved debug output (mainly DEEP_TRACE)
+ Connect() can now take (and defaults to) 'FIRST_AVAILABLE' as the wiimote
index (see header comments).
+ 'wiimote_sample' is now auto-cleared on construction
+ Adjusted max 'theoretical' raw IR coord values (1023x767) to largest
actually observed, to output full 0-1 float range.
+ **Inverted** IR X float coord to match traditional 'left = 0' convention
(raw coords unaffected for now).
+ Added state recording ability to aid state/motion analysis. See RecordState();
- removed RequestBatteryUpdate() (battery level is now periodically refreshed)
- disabled ...CALIBRATION_CHANGED flags (not useful)
Demo : should now work pre-XP.
ReadMe: added Wiimote/PC installation notes (MS stack is especially tricky).
0.81b:
+ connection loss is now detected (via failed writes)
+ ConnectionWasLost() added
+ report modes renamed for clarity.
+ Connect(): added 'force_hidwrites' (for testing only).
+ Extension connections now seem to be reliable.
+ Battery is now periodically refreshed (also used for loss detection)
+ 'BatteryRaw' was set incorrectly
+ added 'wiimote::ClassicButtonNameFromBit[]'
+ Demo : Classic Controller data shown.
+ Demo : IR dot sizes now reported when possible (only if extension
data isn't requested as they're not available then).
+ License: 'no harm' clause added.
+ ReadMe : added build notes etc.
0.1b:
First release.
