bpi-gpio

A minimal package to control the GPIO pins for BananaPi using node.

Description

As mentioned this package will help you to easily control the GPIO pins for BPI boards, but it is tested just on BPI m2 berry

Dependencies

This Library uses (gpio) utility from wiringPi . To make sure that wiringPi is installed, run the following command on the Terminal

gpio -v

If there are no errors, you are good to go :)

Usage

This package has just three functions.

1.mode(pin, mode) This function takes two arguments the first one is the GPIO number and the second is the mode, until now we have just two modes(OUTPUT or INPUT)

Example:

const GPIO = require('bpi-gpio') const LED = 17 GPIO.mode(LED, GPIO.OUTPUT)

2.read(pin) This function takes just one argument which is the GPIO pin number.

Example:

const GPIO = require('bpi-gpio') const LED = 17 GPIO.read(LED)

3.write(pin, value) This function takes two arguments the first one is the GPIO pin number and the second is the value you want to write hint: you should change the pin mode to OUTPUT before using this function.

Example:

const GPIO = require('bpi-gpio') const LED = 17 GPIO.mode(LED, GPIO.OUTPUT) GPIO.write(LED, GPIO.HIGH)
