#          Wiimote State message containing one complete Wiimote state

# Note: For ease of manipulation this message often uses
#       int8[] when a bit vector would work. One might
#       wish to use uint8[], but then Python takes
#       the respective structure as a string and disallows
#       item assignment.

# Gyro reading
#-----------------------------
# In radians/sec. If reading is invalid,
# for instance b/c no gyro is attached to the Wii, then
# set first element of covariance to -1 (same as imu_data.msg):
# Covariance matrix (roll, pitch, yaw) in radians^2/sec^2.

# IR Light sensor (Camera)
#-----------------------------
# The Wiimote handles up to four light sources, 
# and the wiimote_controller software is written to
# that limit as well. For future expansion
# we make the following array extensible, rather
# than locking its length down to four:

# Wiimote battery
#-----------------------------
# A battery reading consists of two numbers: 
# the battery percentage, and the raw reading.
# Maximum battery is 208 units (unknown how this
# relates to electrical properties):

# Value of zero means all is well. (Currently NOT used).
