NAME
Device::PCA9685 - I2C interface to PCA9685 16 channel 12 bit PWM
Generator
VERSION
version 0.003
SYNOPSIS
use Device::PWMGenerator::PCA9685;
my $dev = Device::PWMGenerator::PCA9685->new(
I2CBusDevicePath => '/dev/i2c-1', # this would be '//dev/i2c-dev-0 for Model A Pi
debug => 1,
frequency => 400, #Hz
);
$dev->enable();
$dev->setChannelPWM(4,0,$dutycycle); # Duty cycle values between 0 and 4096 channel 4
DESCRIPTION
This module provides a Object oriented interface to Adafruit 16
channel 12 bit PWM Generator(PCA9685). Before you use this module
make sure you follow install Prerequisites for Device::SMBus
ATTRIBUTES
I2CBusDevicePath
this is the device file path for your I2CBus that the PCA9685 is
connected on e.g. /dev/i2c-1 This must be provided during object
creation.
PWMGenerator
$self->PWMGenerator->enable();
$self->PWMGenerator->setChannelPWM($channel,$pulseOnPoint,$pulseOffPoint);
The PCA9685 offers a 12 bit resolution which means across a duty
cycle you may set and unset the PWM at 4096 different point. Range of
values for $pulseOnPoint and $pulseOffPoint is 0 to 4095 Range of
values of $channel is 0 to 15
This is a object of Device::PWMGenerator::PCA9685
