end-point calibration is not required unless the flight board outputs different
ranges.
First, remove all propellers! Check to see if there are calibration steps
documented for your flight controller board. KK2 boards have a two-button
procedure that performs automatical calibration. With KK boards, the Yaw
pot must be set to the minimum position in order to enable pass-through
mode from the receiver input to the ESC output, and the ESCs are then
calibrated to the radio's throttle throw. With the Naze32, try the console
settings “set minthrottle=1064” and “set maxthrottle=1864”. The same
settings may be used for AutoQuad or other boards that allow the
endpoints to be specified.
If none of the above options are available, calibration may be performed
manually. First, remove all propellers! Disconnect the power to the ESCs.
Connect the ESC PWM input directly to the receiver's throttle channel, or
to a servo tester.
Set the radio throttle or servo tester to the highest position, then connect
power to the ESC. The motor should produce a series of initialization
beeps increasing in pitch, followed by another beep matching the pitch of
the last initialization beep. This indicates that the calibration mode has
been entered, and the pulse length has been learned.
Move the stick or knob to the lowest position. Two beeps of the same pitch
should be emitted. This indicates that the low pulse length has been
learned. If the RC Car-style reversible mode has been enabled
(RC_PULS_NEUTRAL), move the stick or knob to the center, and wait for
three beeps. This indicates that the neutral (center) pulse length has been
learned.
The ESC will then save the settings and exit calibration mode. If the input
is still at the same position, the ESC will arm (producing a higher pitched,
long beep), and function normally.
NOTE: Throttle calibration is disabled to avoid accidental calibration if the
ESC is reset by brown- out during previous operation. If the power is not
connected cleanly during the above steps, the power-up may also be
detected as a brown-out. If the rising beeps are not heard while attempting
to calibrate, disconnect the power for a few seconds, then try again.
