npm i adafruit-i2c-pwm-driver
const makePwmDriver = require('adafruit-i2c-pwm-driver')
const pwmDriver = makePwmDriver({address: 0x40, device: '/dev/i2c-1'})
pwmDriver.setPWMFreq(50)
pwmDriver.setPWM(2) // channel, on , offTo configure I2c on your Raspberry-pi / Beaglebone please see here
you can find a simple example here
makePwmDriver({address:Number,device:String,debug:Bool})
Setting up a new PwmDriver
- address: Address of the i2c panel, e.g. 0x20
- device: Device name, e.g. '/dev/i2c-1' (defaults to /dev/i2c-1)
- debug: flag used to display debug messages
pwmDriver.setPWMFreq(frequency:Number)
Set the PWM frequency to the provided value (in hertz).
pwmDriver.setPWM(channel:Number, on:Number, off:Number)
Sets a single PWM channel.
pwmDriver.setALLPWM(channel:Number, on:Number, off:Number)
Sets all PWM channels.
