Apr 21, 2009 Hi, I would like to make my own Parallel port to I2C adapter which can be used to read and write I2C devices. Any one has reference schematics for it. This is my last project, a dual USB converter to serial and I2C. Wendell Willkie One World Pdf. With this tool, you can listen TX and RX lines at the same time on serial communications. Fortigate Vm Software Austin on this page. PCA9564 Parallel bus to I2C-bus controller. •Parallel-bus to I2C-bus protocol converter and interface. High-speed parallel buses and the serial I 2C-bus. The NJU3730 is a serial-to-parallel converter IC,which converts I2C serial data into 3 bits parallel data.

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.

Cyberlink Powerdirector 7 Full Version. 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Down here you can find the original LM_Sensors packages (they are a little outdated, I'm trying to install a newer version soon) and the patches against them.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.

The 74HC595 is a very handy IC used in many microcontroller projects. You clock in 8 bits of data (like, on/off settings for 8 LEDs) via two lines, and when you toggle a third line, it pops these settings out on 8 outputs on the IC. So you trade 3 valuable lines on your microcontroller for 8 outputs - a pretty good deal, eh?
