The Interrupts block monitors a GPIO pin for interrupts.

• pin: The GPIO BCM pin to monitor for interrupts.
• pull_up_down: Value of pin when it's logic level is neither high nor low.

• default: Any list of signals.

• default: At an interupt, the 'pin' is added to the signal.

None

• RPi.GPIO

{
  'input_attr': 'I was already here',
  'pin': 'pin_property'
}

The Read block reads from a variety of gpio interfaces. A 'pin' read is triggered by any incoming signal.

• pin: The GPIO BCM pin to read.
• pull_up_down: Value of pin when it's logic level is neither high nor low.

• default: Any list of signals.

• default: Each input signal triggers a pin read. The boolean pin value is added to the signal.

None

• RPi.GPIO

Any list of signals.

{
  'input_attr': 'I was already here',
  'value': True
}

The Write block emits a signal containing a boolean value to a specified GPIO pin.

• pin: The GPIO BCM pin to write.
• value: Boolean value to write to pin.

• default: Any list of signals.

• default: Each input signal triggers a pin write. The boolean pin value is added to the signal.

None

• RPi.GPIO

Any list of signals.
