Kernel driver i2c-parport-light

Author: Jean Delvare <>

This driver is a light version of i2c-parport. It doesn’t depend on the parport driver, and uses direct I/O access instead. This might be preferred on embedded systems where wasting memory for the clean but heavy parport handling is not an option. The drawback is a reduced portability and the impossibility to daisy-chain other parallel port devices.

Please see i2c-parport for documentation.

Module parameters:

  • type: type of adapter (see i2c-parport or modinfo)
  • base: base I/O address Default is 0x378 which is fairly common for parallel ports, at least on PC.
  • irq: optional IRQ This must be passed if you want SMBus alert support, assuming your adapter actually supports this.
