Firmata Digital Output Pulse Channel

Description

Digital output pulse channel on a Firmata Device.

A digital output pulse channel triggers output “pulses” on its associated pin. Whenever a pulse duration is assigned to value, MWorks sends a pulse command to the Firmata device. Upon receiving the command, the device sets the pin to high/true. Once the requested interval (as measured by the device’s onboard clock) has elapsed, the device sets the pin back to low/false.

Note: Firmata devices require pulse durations to be specified in milliseconds. MWorks converts durations assigned to value from microseconds to milliseconds before sending them to the device.

Signature

iochannel/firmata_digital_output_pulse

Required Parameters

pin_number

Example

4

Output pin number

value

Variable from which to read pulse duration (in microseconds). Assigning a value to the variable causes the pulse to begin immediately.

Note: Pulse durations must be whole numbers of milliseconds.
