Description

The RS232 I2C Adapter is an universal applicable I2C-tool with a 128 bytes of buffer and a SCL-frequency up to 100 kHz. With the RS232 I2C Adapter as master numerous bus participants can be adressed such as IOExpander, sensors, LCDs, 7-segment display, stepping motors, AD/DA converters, real time clocks, tone generators, RAM, EEProms, etc.

 

No separate power packs for voltage supply are needed. Power supply is provided from the RS232- Interface (DTR & RTS). Power consumption less than 5mA.

 

Labview VIs and a 32bit DLL (for Windows) are included in delivery. This makes the integration of the adapter into own applications possible.

 

It is possible to communicate with the adapter using Windows API functions such as CreateFile(), WriteFile() and ReadFile(). A simple software interface (ASCII commands) is available.

 

Some of the software Tools are for the developer very helpfully. Thus it is possible to test immediately I2C devices. The software “IIC Control” supports EEPROMS of 1kbit (128 bytes) to 1Mbit (128k byte).
