close! clj/s

(close! self)

Closes this object

export! clj/s

(export! port)

format-raw-digital clj/s multimethod

Formats the raw values received from digital reads of pin state, or digital events.

The type specified is a keyword.

GpioChannelProvider clj/s protocol

create-edge-channel clj/s

(create-edge-channel port)

Returns a core.async channel on which events will be put

release-edge-channel! clj/s

(release-edge-channel! port channel)

set-edge! clj/s

(set-edge! providor setting)

GpioPort clj/s protocol

read-value clj/s

(read-value port)

Return the value of the port

set-active-low! clj/s

(set-active-low! port active-low?)

Invert the logic of the value pin for both reading and writing so that a high == 0 and low == 1.

set-direction! clj/s

(set-direction! port direction)

Sets the direction of this port: in or out.

toggle! clj/s

(toggle! port)

Flips the value of the port

write-value! clj/s

(write-value! port value)

Writes the value to the port. The value may be specified as :high, :low (and symbol or string variations), , �, or 1, 0

high-low-value clj/s

(high-low-value value)

open-channel-port clj/s

(open-channel-port port & opts)

Opens a port which can be used for listening to value changes. In addition to the options map for open-port, the following are available:

• :event-buffer-size - the size of the change events buffer. Defaults to 1
• :timeout - sets a timeout for the OS polling wait time. Defaults to -1, which waits indefinitely
• :edge - sets the edge value- :rising, :falling, or :both

open-port clj/s

(open-port port & opts)

Opens a port from which values may be read or written. Args:

• port - the gpio pin number
• opts: optional keyword args
  • :direction - sets the initial direction
  • :active-low? - sets the port as "active low", value true or false
  • :initial-value - sets the intitial value of the pin.
  • :digital-result-format - describes the format for digital values on read This can be one of #{:keyword :symbol :integer :boolean :char}
  • :from-raw-fn - a converter function, which takes the char value ( or �) read and converts it into a meaningful value. Overrides the default formatter

unexport! clj/s

(unexport! port)
