Description

In order to support the user for integration of own ASIC module with I²C-
Interface, we have developed this easy to handle PC interface. The probe 
can be operated with a PC to test the functionality and capture the measured 
values of sensors.
In principle it is an USB on a I²C-converter, which is addressed by a simple 
ASCII sequence. The USB-driver software emulates a serial COMinterface.
The ASCII protocol of data communication is well documented. Hence,
integration into own programs through standard communication routines of all 
the modern programming languages is possible.
The interface adapter is also suitable for accessing the ASIC, for example, to 
program another I²C address.
Further information on ASIC and programming can be obtained on request.
