USB-to-I2C Elite, USB-to-I2C Professional, and LPT-to-I2C SE Professional products are powerful I2C hardware and software packages which allows you to begin sending I2C messages within minutes of installation.

USB-to-I2C Professional is a general purpose I2C and SPI tool that allows a user to communicate with I2C and SPI devices. USB-to-I2C includes USB-based hardware and Windows software, compatible with 32-bit and 64-bit versions of XP, Vista, Windows 7, and Windows 8.
A DLL is included allowing you to create your own I2C and SPI applications.
Examples using Visual C++, Visual Basic, C#, Delphi, and C++ Builder are provided.

USB-to-I2C Elite has a similar user interface to the Professional version, but the hardware uses a 60MHz ARM7 processor for unrivaled performance. The USB-to-I2C family of products are the most complete USB-based I2C and SPI development tools available.

LPT-to-I2C SE Professional is a wide operating voltage (down to 0.9V) I2C hardware and Windows software tool for communicating with I2C and SMBus hardware. A DLL is included that can be used to create your own custom i2c applications. Examples using Visual C++, Visual Basic, Delphi, and C++ Builder are provided. The LPT-to-I2C SE host adapter with serial EEPROM is shipped with this product. The I2C host adapter includes an on-board socket for programming.

I2C & SPI Isolator and Voltage Level Shifter offers features that are important in many applications. First, it provides 3.75kV of isolation between the USB-to-I2C hardware and the user's target hardware. This can protect both the USB-to-I2C hardware, as well as your PC from damage in the event of an over-voltage occurence. It also provides level shifting for both the I2C and SPI signals. While the USB-to-I2C side operates at 3.3V, the isolated side is capable of operating between 2.5 and 5.5V.

February, 2013
February has been a busy month for i2ctools! We have now released the v6 software upgrades for USB-to-I2C Professional and Elite. Of course, software updates are always free.

USB-to-I2C v6 software for Professional hardware released.

The 32-bit and 64-bit version 6 software includes the following updates and improvements:
1. Support for Windows 8 operating system
2. Improved Expert Mode user interface. Completely rewritten for speed optimization.
3. More I2C devices supported. There are now 72 of the most common I2C devices supported, as well as the EEPROM, and general purpose interfaces.
The installation file can be found on the Downloads page.
