+| //channel//  | StepPulse channel (StepAccel supports only 0)  |
+| //port//     | Output port                                    |
+| //freq//     | Output frequency (Up to 15000)                 |

+This command outputs a set number of pulses at a set frequency (up to
+kHz). [[:cubloc:freqout:|FreqOut]] and [[:cubloc:pwm:|Pwm]] can also output pulses, but the number of pulses
+cannot be controlled and only the dedicated PWM ports can be used. With
+''StepPulse'', any output port can be used, and the number of pulses and
+pulse frequency can be controlled.
+Depending on the Cubloc module used, the number of available channels
+may change. Please refer to the following table for module specific
+information.
+^Module ^Channels ^Channel ^PWM Channels that cannot be used during use of the command^
+|CB2XX, CB3XX, CT1721C| 1 |0 |Channel 0: PWM 3, 4, 5|
+|CB400, CB405, CB405RT | 2 |0 or 1 |Channel 0: PWM 3, 4, 5 \\ Channel 1: PWM 6, 7, 8|
+''StepPulse'' uses the Cubloc processor’s PWM counters. When using this
+command, PWM3, PWM4, and PWM5 cannot be used.
+For the CB400/CB405/CB405RT, when using channel 1, PWM6, PWM7, and PWM8
+cannot be used. With the CB2XX and CB3XX series, only channel 0 may be used. With
+the the CB400/CB405/CB405RT, StepPulse can be used on 2 different channels
+simultaneously.
+You can use any of the available I/O ports on the Cubloc. When the
+''StepPulse'' command is executed, the specified port's I/O mode is
+automatically set to output. Even after the command has finished
+generating pulses, the port's I/O mode remains output.
+The output frequency can be set from 1hz to 15kHz.
+This command will run in the background independently, so system
+resources can be used for other tasks.
+''StepPulse'' should not be used simultaneously with ''StepAccel'' command.
+===== Example =====
+<code xbasic>
+Const Device = CB280
+Do
+  Do While In(0) = 1
+  Loop
+  StepPulse 0, 5, 5000, 300
+  Do While In(0) = 0
+  Loop
+Loop
+</code>
+When the port 0 switch is pressed, port 5 will output 300 pulses at the
+speed of 5kHz. The following is a circuit diagram for the code above:

+A stepper motor controller can be created using a stepper motor and
+stepper motor driver as shown below.
+{{ :cubloc:steppulse:steppermotor.png?nolink |}}
+Connect 3 Cubloc I/O ports to the stepper motor driver. The DISABLE and
+DIRECTION pins are only to enable and set the direction of the stepper
+motor.
+Please refer to your stepper motor specifications for how many pulses are
+required to move the stepper motor one rotation.
