Firmata Digital Input Pulse Channel¶
Description¶
Digital input pulse channel on a Firmata Device.
A digital input pulse channel measures the duration of input “pulses” on its associated pin. Whenever the pin transitions to high/true, the Firmata device records the pulse start time (as measured by its onboard clock). When the pin transitions back to low/false, the device subtracts the start time from the current time and reports the elapsed duration to MWorks.
Note: Firmata devices always report pulse durations in milliseconds. MWorks converts these to microseconds before assigning them to value.
