USB-to-I2C Professional

USB-to-I2C Professional is a general purpose I2C and SPI interface tool that allows a user to communicate with any I2C or SPI slave devices. USB-to-I2C includes the USB-based hardware and Windows software and driver that is compatible with Windows XP, Vista, and Windows 7. Support for both 32-bit and 64-bit operating systems are included.

The USB-to-I2C software has the capability to program I2C and SPI serial eeproms, ram, and fram from 16 bytes (128 bit) to 512k bits (64k bytes). Universal modes provide the flexibility to communicate with any I2C slave device.

The hardware is capable of transmitting I2C up to 1 Mb/s (note the I2C spec limits the speed to 400 Kb/s) and SPI up to 4Mb/s. There are 3.3V and 5V switchable power outputs on the USB-to-I2C hardware allowing you to supply low-power target systems.

USB-to-I2C Professional includes:

- the USB-to-I2C hardware

- 3 ft USB 2.0 cable

- USB DLL allowing you to create your own I2C and SPI applications

- DLL examples for Visual C++, Visual C#, Visual Basic, Delphi, and C++ Builder

- compatible with LabView

- USB-to-SPI Windows software

- USB-to-I2C Windows application with universal I2C support and a custom interface for the following popular I2C devices:
