Device::SMBus - Perl interface for smbus using libi2c-dev library.

VERSION

version 0.04

SYNOPSIS

use Device::SMBus;
$dev = Device::SMBus->new(
  I2CBusDevicePath => '/dev/i2c-1',
  I2CDeviceAddress => 0x1e,
);
print $dev->readByteData(0x20);

DESCRIPTION

This is a perl interface to smbus interface using libi2c-dev library.

ATTRIBUTES

I2CBusDevicePath

Device path of the I2C Device.

* On Raspberry Pi Model A this would usually be /dev/i2c-0 if you are using the default pins.
* On Raspberry Pi Model B this would usually be /dev/i2c-1 if you are using the default pins.

I2CDeviceAddress

This is the Address of the device on the I2C bus, this is usually available in the device Datasheet.

* for /dev/i2c-0 look at output of `sudo i2cdetect -y 0' 
* for /dev/i2c-1 look at output of `sudo i2cdetect -y 1'

METHODS

readByteData

$self->readByteData($register_address)

writeByteData

$self->writeByteData($register_address,$value)

USAGE

  • This module provides a simplified object oriented interface to the libi2c-dev library for accessing electronic peripherals connected on the I2C bus. It uses Mo, a scaled down version of Moose without any data checks to improve speed.
