Device::SMBus - Perl interface for smbus using libi2c-dev library.
version 0.10
use Device::SMBus; $dev = Device::SMBus->new( I2CBusDevicePath => '/dev/i2c-1', I2CDeviceAddress => 0x1e, ); print $dev->readByteData(0x20);
This is a perl interface to smbus interface using libi2c-dev library.
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.
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'
returns IO::Handle->error() for the device handle since the last clearerr
