<p>
 | 
						|
Discrete input for the Beaglebone Black. Sends a message with payload 0 or 1 on the
 | 
						|
first output when the pin changes state, and logs the total time in the active state.
 | 
						|
</p>
 | 
						|
<p>
 | 
						|
Sends a message with a payload of the current total active time
 | 
						|
(in seconds) on the second output at selectable intervals. An input message with topic 'load'
 | 
						|
and a numeric payload will set the total active time to that value: any other input message
 | 
						|
will reset it to zero.
 | 
						|
</p>
 | 
						|
<p>
 | 
						|
The active state may be set to be high or low: this only affects the calculation
 | 
						|
of the active time, not the pin state value sent on the first output.
 | 
						|
</p>
 | 
						|
<p>
 | 
						|
The pin state messages may be generated for both directions of change, or for just 0 to 1
 | 
						|
or just 1 to 0 changes. This is useful to generate a single message from a button
 | 
						|
press. When using buttons or switches, enable debouncing to improve reliability.

Sets the output pin high or low depending on the payload of the input message. Numeric

payloads > 0.5 are 'high' (1), payloads <= 0.5 are 'low' (0). Other payloads which

evaluate to true are 'high', if not then 'low'. Selecting the Inverting checkbox will

switch the sense of the pin output.

</p>

If the Toggle state checkbox is checked, the message content is ignored: successive

messages cause the pin to toggle between 0 and 1.

The pin will be initially set to the given Startup state until the first message arrives:

Pulse an output pin on the Beaglebone Black.

<p>

						|
Pulses the output pin for the set time after receiving an input message, unless the
 | 
						|
message has a topic including the text 'time' and a numeric payload. In this case, the
 | 
						|
the pulse time will be the value of the payload in seconds. If the time from either
 | 
						|
source is < 0.001 seconds, no pulse is generated.
 | 
						|
</p>
 | 
						|
<p>
 | 
						|
In retriggerable mode, a second message within the pulse period will extend the duration
 |

of the pulse by the time value: in non-retriggerable mode, input messages arriving during

the duration of the pulse are ignored.

</p>

The pin state of the pulse may be set to either 0 or 1: the output pin will switch
 | 
						|
back to the other state after the pulse time. An output message is generated each time
 | 
						|
the pin changes state: its payload is the new state (0 or 1).
