USB I2C Adapter (Master)                                

USB I2C Adapter (Master)

This Adapter is still available but NOT RECOMMENDED FOR NEW DESIGN please see the new Adapter.

 

The USB I2C Adapter is a universally applicable USB to I2C converter with a SCL-frequency up to 400 kHz. With the USB-I2C-Adapter as masters numerous bus participants can be addressed purposefully via a USB such as IO-Expander, sensors, LCDs, 7-segment display, stepping motors, AD/DA converters, real time clocks, tone generators, RAM, EEPROM, etc.

 

The Tool does not need any additional drivers under Windows. The adapter uses the standard HID driver offered by Windows (WIN98SE, ME, 2000, XP).

 

The SCL-frequency is adjustable by software from 1kHz up to 400kHz. The duty cycle SCL-High/SCL-Low can be also individually adjusted.

 

The adapter has an interrupt input. Thus it is possible to react to external events. This interrupt input can be activated (rising o. falling edge) or deactivated by software.

 

No separate power packs for voltage supply are needed. 3,3V and 5V outputs are available. The total current consumed the adapter and the target system must be limited to 100mA by the user when using these power outputs. Thus e.g. an EEPROM Programm or a temperatue measuring- station can be realized.

 

A 32-bit DLL is also included in delivery. This makes the integration of the adapter into own applications possible. A detailed description and some examples to the DLL are also included. e.g. you as developer could immediately begin with the actual work without dealing with troublesome drivers.

 

Some of the software Tools e.g. the "USB-I2C-Expert" are for the developer very helpfully. Thus it is possible to test immediately I2C devices. The "USB I2C EEPROM" supports EEPROMS of 1kbit (128 bytes) to 512kbit (64k byte).
