2.5.2
CALIBRATION
The default input pulse width times should be compatible with most controllers. However, if a different mapping is
desired, the SPARK can be calibrated as follows:
The SPARK must be receiving a signal to begin calibration. It is recommended that the motor be disconnected while
calibrating to prevent unexpected movement.
1.
Press and hold the MODE button for 3 seconds. The STATUS LED will start to blink white.
2.
Sweep the input signal through the entire desired range.
3.
Return the signal to the desired neutral value.
4.
Release the MODE button.
If the calibration routine was successful, the status LED will blink white and green for several seconds while the SPARK
immediately begins responding to the new signal range.
If the calibration routine was unsuccessful, the Status LED will blink white and red and the previous values are restored.
Check that the signal didn't violate the timing constraints and/or the neutral value wasn't too close to the full forward or
full reverse values. See section 2.6 STATUS LED for more information.
Calibration values are saved to memory and persist through a power cycle.
2.5.3
FACTORY RESET
The SPARK can be reset to its factory default settings with the following procedure:
1.
Disconnect power to the SPARK
2.
Press and hold the MODE button
3.
Reconnect power while still holding the button
4.
The Status LED will illuminate white
5.
Release the button
The Status LED will blink white and green indicating that the factory defaults have been restored. See section 2.6
STATUS LED for more information.
