When the THE MOST COMMONLY ASKED I2C QUESTIONS
General Questions
Question
I get corrupted transfers why is this?
Answer
The most likely reason for corrupted transfers is either incorrect bus termination or
excessive capacitance - see the manual for details.
Question
Do you have software to talk to my........?
Answer
Unfortunately there are too many I2C devices for us to be able to offer complete
solutions - although we can supply a windows based application called WINI2C which is
designed for those just starting I2C or wishing to perform simple I2C tasks, please
contact our sales team or look on our web site,or further
information.
Question
I am trying to read from a device, the first time my software works fine but when I
try again I can't get anything what's wrong?
Answer
Please check that you are changing the value of Setnack in accordance with the
manual, it is likely that you have not made Setnack 1 for the last byte being read.
Windows Questions
Question
I have read the manual and still cannot get the communications to run. What do I
do next?
Answer
Check that you have fully implemented the protocol between the Adapter and the other
I2C devices see the device manufacturers data sheet for details.
Check that the software you have written is logically and syntactically correct - this is
probably the most common cause of software faults we have to deal with.
Send us the following details:-
1)The link settings of the Adapter.
2)A sketch of the relevant I2C hardware including the location of bus termination.
3)The type and speed of processor within your PC and which operating system, you are
running.
4)Brief software listings, or which Calibre software you are running.
5)The serial number of your I2C Adapter, or when you purchased it.
