Project now lives here: WiringPi/WiringPi-Node.

Node.js bindings to WiringPi

> npm install wiring-pi

var wpi = require('wiring-pi');

wpi.setup();

wpi.setup('gpio');

Valid Modes:

• wpi: sets up pin numbering with wiringPiSetup
• gpio: sets up pin numbers with wiringPiSetupGpio
• sys: sets up pin numbers with wiringPiSetupSys

See WiringPi Pins for the differences in Pin numbering;

wpi.pinMode(0, wpi.modes.OUTPUT);

• pin: pin number
• mode: wpi.modes.INPUT, wpi.modes.OUTPUT, or wpi.modes.PWM_OUTPUT

wpi.digitalWrite(0, wpi.HIGH);

wpi.digitalWrite(0, wpi.LOW);

• pin: pin number
• value: 0 (wpi.LOW) or 1 (wpi.HIGH)

wpi.digitalRead(0);
//=> 1

• pin: pin number

These have the same arguments as their WiringPi counterparts

• piBoardRev
• pwmSetRange
• pwmSetClock
• pwmWrite
