This page describes a mode of operation for a driver. See the Working with Drivers section of the FAST Serial Protocol documentation for details about how to use it.

Motor driver that uses two Drivers for Motor Control (Enable/Direction) e.g. Rudy’s mouth in Funhouse.



  • FAST Driver number, zero based.


  • Bit 0 Disabled/Enabled(1)

  • Bit 3 Standby/RunMotion(1)

  • Bit 4 Forward/Reverse(1)


Not Used

  • Amount of time in mS to run Motor.


See PWM Byte Sequence Table

Rudy FunHouse Driver example:

Setup the Linked driver first. The command below sets driver 0x15 to be a linked Driver (Motor Direction)


This sets the driver to be controlled by a main linked driver. Control is accomplished by the main driver writing to param1 and param2 of the linked driver to control output on/off. Once this command is issued, the driver does not need any further commands sent to it.

Close Mouth for 0x20ms Full Power


Open Mouth for 0x20ms Full Power


Open Mouth for 0x15ms 50% POWER


Issuing a new DL:14,xxxx command while the motor is in operation will cancel the prior action and start moving the motor based on the new instruction.
