js_gpio
GPIO module
let eventLoop = require("event_loop");
let gpio = require("gpio");
This module depends on the event_loop module, so it must only be imported
after event_loop is imported.
Example
let eventLoop = require("event_loop");
let gpio = require("gpio");
let led = gpio.get("pc3");
led.init({ direction: "out", outMode: "push_pull" });
led.write(true);
delay(1000);
led.write(false);
delay(1000);
API reference
get
Gets a Pin object that can be used to manage a pin.
Parameters
pin: pin identifier (examples:"pc3",7,"pa6",3)
Returns
A Pin object
Pin object
Pin.init()
Configures a pin
Parameters
mode:Modeobject:direction(required): either"in"or"out"outMode(required fordirection: "out"): either"open_drain"or"push_pull"inMode(required fordirection: "in"): either"analog","plain_digital","interrupt"or"event"edge(required forinMode: "interrupt"or"event"): either"rising","falling"or"both"pull(optional): either"up","down"or unset
Pin.write()
Writes a digital value to a pin configured with direction: "out"
Parameters
value: boolean logic level to write
Pin.read()
Reads a digital value from a pin configured with direction: "in" and any
inMode except "analog"
Returns
Boolean logic level
Pin.read_analog()
Reads an analog voltage level in millivolts from a pin configured with
direction: "in" and inMode: "analog"
Returns
Voltage on pin in millivolts
Pin.interrupt()
Attaches an interrupt to a pin configured with direction: "in" and
inMode: "interrupt" or "event"
Returns
An event loop Contract object that identifies the interrupt event source. The
event does not produce any extra data.
