NAME Device::SMBus - Perl interface for smbus using libi2c-dev library. VERSION version 0.05 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 writeQuick $self->writeQuick($value) readByte $self->readByte() writeByte $self->writeByte() readByteData $self->readByteData($register_address) writeByteData $self->writeByteData($register_address,$value) readWordData $self->readWordData($register_address) writeWordData $self->writeWordData($register_address,$value) processCall $self->processCall($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 Moo, a scaled down version of Moose without any data checks to improve speed. see ALSO * Moo * IO::File * Fcntl SUPPORT Bugs / Feature Requests Please report any bugs or feature requests through github at .
