Please first review
the
I2C2002-1A Quick Start Guide and
the
I2C2002-1A
Evaluation Board Appnote before
using your I2C2002-1A kit!
Q: What is included in
this kit?
A: The kit contains the
NXP (Philips) I2C2002-1A Evaluation Board (PCAxxx I2C devices), the
I2CPortv2.0 printer port
adapter, and the latest version of Win-I2CNT on CD.
Cables and a universal-input switching AC power adapter (USA plug) are
also included in the kit.
Q: What's the quickest
way to get the I2C2002-1A kit up and running?
A: See the
I2C2002-1A Quick Start Guide for recommended starting configuration
and testing your kit.
Q: Where do I get more
technical information for the Philips I2C devices and the I2C2002-1A Evaluation
Board?
A: Link to the NXP (Philips)Semiconductors'
website for I2C-2002-1A Evaluation Board:
http://www.standardics.nxp.com/support/boards/i2c20021/
Link to latest version of the I2C2002-1A evaluation
board appnote (instructions and examples):

Q: Is a full schematic
available for the I2C2002-1A Evaluation Board?
A: I2C2002-1A_Full-Sch.pdf
Q: What are the USB connectors
on the I2C2002-1A Evaluation Board and the small "USB Adapter Board" ?
A: These connections
are NOT for "USB", but allow using a common USB cable to connect buffered
I2C from the
I2C2002-1A Evaluation Board to the "USB Adapter Board" via the P82B96 I2C
bus buffer ICs.
These
connectors should NEVER be mistakenly connected to a
PC USB port or USB peripheral!
The
only possible I2C connection to your PC is through the I2CPortv2.0 parallel
(LPT) port adapter.
Q: "SDA Stuck Low" error
message results from Win-I2CNT menu when any I2C communication is attempted.
A: Make sure the 4-pin
I2C cable is properly connected between the I2CPortv2.0 adapter and the
I2C2002-1 board.
If the included I2C cable has guide keys on the 4-pin connectors, the guide
keys should be facing the opposite
side of the DB-25 plug on the I2CPortv2.0 adapter
Disconnect the I2C cable from the I2CPortv2.0 adapter and read the 256x8
EEProm to verify adapter & software
functionality. This error message may also result if the connected
I2C2002-1 eval board is not getting 9v power.
The green LED next to the Power connector should illuminate when power
is first applied to the I2C2002-1A board
(other green LEDs next to the PCA9561 device may also be lit).
The I2C2002-1A QuickStartGuide
outlines the recommended configuration and steps to get the kit running
qquickly.
Q: Reading the LM75A temperature
sensor(s) does not reflect any temperature changes in the Win-I2CNT display.
A: Make sure one of the
two channels of the PCA9543 (2:1 I2C Mux) has been programmed to select
the desired
LM75A temp sensor IC.
Q: Where do I find additional
information regarding the Win-I2CNT software and I2CPortv2.0 printer port
adapter?
A: Refer to the
Win-I2CNT
FAQ page.
Q: I want to write my
own I2C software in Visual Basic, C++, Delphi, etc. Are the drivers
and examples available?
A: The Win-I2CNTDLL
kit provides this capability.
Q: How do I determine
whether or not I have the latest version of Win-I2CNT for the I2C2002-1A
Kit?
A: See <Help-About>
from the main Win-I2CNT menu to verify the installed version.
Win-I2CNT v4.7 is the current release; newer beta versions may also be
available for download.
Refer to your kit documentation or view the <Regformxx.txt> file in
the Win-I2CNT installed directory of your HDD.
Q: Who do I contact for
technical support?
A: Technical support
for the I2C2002-1A Evaluation Board and associated PCA95xx ICs: i2c.support@NXP.com
Technical
support for the Win-I2CNT software and the I2CPortv2.0 adapter: support@demoboard.com
Q: How does the I2C2002-1A
Evaluation Board differ from the earlier I2C2002-1 Evaluation Board?
A: The revised Philips
I2C2002-1A Evaluation board is a new PCB that contains the same I2C peripheral
devices;
The I2C2002-1A board incorporates design
changes and improvements over the earlier
I2C2002-1 design.
