A RS232 serial port driver for the I2C bus / LM_Sensors package Like all other pages here, even this page is always under construction. The page layout still needs some work, whereas the content is in a usable state. What you currently find here are two patches against an older Version of the LM_Sensors package () and a drawing of the hardware adapter.

A RS232 serial port driver for the I2C bus The I2C bus is a bus system formerly designed by Phillips for different ICs inside a Device to communicate to each other. It is today found (at least in a mod ified way, the SMBus) on every up-to-date Mainboard to controll all these temperature- fan- and voltage gimmics and much other things. It is also used as a low-cost way to connect single ICs or devices to a PC with low hardware requirements. The LM_Sensors package is a set of modules that drive a number of i2c bus devices. It is split in two packages. The i2c packages provides a set of 'bus drivers', that is drivers for certain hardware (Interface ICs or self-made adapters) to get to a general software interface to the I2C bus. The lm_sensors package contains modules that can communicate to different chips that are connected to a present I2C bus, like LM75 thermometers.

Because there was only an interface for the parallel port existing but none for the serial port, and my parallel port was already used for the printer, I wrote a new module i2c-ser.c that drives an I2C bus over the RS232 serial port (in principle I took the i2c-elv.c module and modified it without really knowing what I was doing). It only needs few Hardware (i.e. An RS232 converter and a quad driver IC) to get to a working I2C bus outside your PC. Down here you can find the original LM_Sensors packages (they are a little outdated, I'm trying to install a newer version soon) and the patches against them. The real module i2c-ser.c is content of the i2c package, the lm_sensors contains only minor changes in the autodetect routines.
