Watch a Raspberry pi GPIO pin (or pins) for changes.
Usage
rpi_monitor(pin_number, numEvents = 0, edge = "both")
Arguments
- pin_number
one or more pin numbers as found on the Raspberry pi GPIO. Use the actual pin numbers (i.e. 1:40)
- numEvents
a number of events to collect. Defaults to 10
- edge
rising|falling|both
Value
a list of events
raw text of each event
event: RISING EDGE|FALLING EDGE
line: the bcm line (not board pin) exhibiting change
timestamp: seconds component
timestamp: nanoseconds component
Examples
if (FALSE) { # is.rpi()
# \donttest{
rpi_monitor(21)
rpi_monitor(21, numEvents = 20)
# }
}
