Bindings for the cwiid library, a working userspace driver along with various applications implementing event drivers, multiple Wiimote connectivity, gesture recognition, and other Wiimote-based functionality.
The current implementation is rather incomplete. In particular:
- Some Haskell functions (those related to rpt mode, rumble, leds) had hard-coded values in them. Therefore, they implemented only a very partial interface to their C counterparts. The new versions should be tested and, if any other function is like this, then exported properly.
- Not all functions/wiimote fields are accessible. In particular, acceleromoter and IR is in testing stage. Nunchuck, calibration, wiimote plus are not handled at all (but will be in the future).
All in all, the code works quite well and is currently being used to implement several real games.

Initialization
cwiidOpen :: IO (Maybe CWiidWiimote)Source
Try to establish a connection to any existing Wiimote using any existing bluetooth interface.
The function returns Nothing
if there is no bluetooth interface
or if no wiimote can be located. If the connection succeeds,
a CWiidWiimote
is returned (inside a Just
), which can be used to
poll the wiimote using other functions.
There is a default timeout of 5 seconds.
- TODO: export cwiid_open_time and cwiid_close as well.
data CWiidWiimote Source
A connection to an existing wiimote. Use cwiidOpen
to
connect to a wiimote and obtain one of these.
State
data CWiidState Source
The state of the wiimote. Use cwiidSetRptMode
to enable/disable
sensors.
- FIXME: incomplete state * FIXME: export get_state
Reception mode
cwiidSetRptMode :: CWiidWiimote -> CUChar -> IO CIntSource
Enable/disable reception of certain sensors. Use 2 to enable buttons.
Leds
cwiidLed1 :: CWiidLedFlagSource
Flag with exactly led 1 enabled. Use combineCwiidLedFlag
to create flags with several leds enabled.
cwiidLed2 :: CWiidLedFlagSource
Flag with exactly led 2 enabled. Use combineCwiidLedFlag
to create flags with several leds enabled.
cwiidLed3 :: CWiidLedFlagSource
Flag with exactly led 2 enabled. Use combineCwiidLedFlag
to create flags with several leds enabled.
cwiidLed4 :: CWiidLedFlagSource
Flag with exactly led 4 enabled. Use combineCwiidLedFlag
to create flags with several leds enabled.
Led operations
cwiidSetLed :: CWiidWiimote -> CWiidLedFlag -> IO CIntSource
Enable/disable certain leds.
Use cwiidLed1
.. cwiidLed4
together with combineCwiidLedFlag
to create a flag with just the leds you want enabled and change
all at once with one operation.
combineCwiidLedFlag :: [CWiidLedFlag] -> CWiidLedFlagSource
Combine several led flags into one led flag with those leds enabled and all other leds disabled.
Rumble
cwiidSetRumble :: CWiidWiimote -> CUChar -> IO CIntSource
Buttons
cwiidGetBtnState :: CWiidWiimote -> IO CWiidBtnFlagSource
Returns a mask with the buttons that are currently pushed.
:: CWiidBtnFlag | The button flags as returned by |
-> CWiidBtnFlag | A mask that flags the button/s that we want to check. |
-> Bool |
Returns True
if the button indicated by the flag is pushed,
False
otherwise.
This is a pure function, so the first argument must be the
button flags as returned by cwiidGetBtnState
.
Accelerometers
cwiidGetAcc :: CWiidWiimote -> IO CWiidAccSource
Obtain accelerometer information. FIXME: read wmgui/main.c:cwiid_acc(1119) to understand how to use this information, what else might need to be exported, and how to calibrate the accelerometers.
Array of accelerometer information. It will always contain exactly three elements.
- TODO: provide a more informative and restrictive interface with exactly three named Int (byte?) fields.

Infra-red
data CWiidIRSrc Source
Internal representation of an infrared point. You should no use it
unless you know what you are doing; use CWiidIR
instead.

cwiidGetIR :: CWiidWiimote -> IO [CWiidIRSrc]Source
