Software User's Manual (5MB)
Q: Where do I get the
latest Win-I2CUSBDLL Software Updates?
A: Win-I2CUSBDLL
v4.x is the newest version, and replaces all previous versions of the software.***
We recommend un-installing previous versions of Win-I2CUSBDLL before installing
the new version to insure the
new drivers are properly installed. Download the new Win-I2CUSBDLL
software from our software Updates Page.
Q: Is Win-I2CUSB/DLL driver
supported under Windows Vista?
A: Win-I2CUSBDLL v4 now
supports Vista; see our software Updates Page
for the new version.
Q: Is Win-I2CUSB/DLL driver
supported under Windows XP or Vista x64 platforms?
A: No, the USB driver
does not support x64 platforms.
Q: ***Will The Win-I2CUSBDLL
kit work with a Win-98 computer?
A: The latest software
v4 is intended to work with Win-2000, Win-XP, and Vista operating
systems.
If problems are encountered installing or running on Win-98 Second Edition
orWin-ME,
then the previous version
(v3.3) might resolve the problem: http://www.demoboard.com/updates/Win-I2CUSBDLL_v330_installation.zip
The software will not work on Win-98, Win-95, DOS, or other operating systems.
Q: Is a demo version available
for Win-I2CUSB/DLL?
A: The full software
version can be downloaded from the Updates
Page and will function as a demo (without the hardware
adapter).
Q: Is source code
supplied with the Win-I2CUSBDLL kit?
A: We do not provide
any source code.
Q: Win-I2CUSBDLL v4 is
newly installed, but Windows returns a "GDIplus.dll" missing error when
attempting to run Win-I2CUSB
A: "gdiplus.dll"
error received when starting the application is usually due to missing
GDI+ files;
These
fare available from Microsoft (search for "gdi+")
Q: Using Win-SPIUSB v4.1.0.x
and Expert Mode Sequence Editor "close" button doesn't close the window?
A: Run the Win-SPIUSB
Web Update from the Main Menu options to install the fixed version
(v4.1.4.0)
Q: Can the Win-I2CUSB/DLL
support byte-level commands that are available in Win-I2CNT/DLL (parallel-port)
version?
A: No, the USB version
does not support the byte level commands that are available in Win-I2CNT.
The Win-I2CUSB adapter uses microcontroller hardware to generate I2C signalling,
making byte-level commands
difficult, and the USB protocol would insert millisecond delays between
bytes.
The parallel adapter (Win-I2CNT) generates I2C signalling directly using
software toggling the hardware-port pins.
Q: How do I determine
the Serial Number of my USB-to-I2C hardware adapter:
A: The s/n sticker is
located on the socketed (PLCC) controller IC.
If the sticker is missing, the s/n can be read from the software main menu
"Options".
The adapter must be connected to the PC USB port and detected by
the software to read the s/n.
Q: When the USB-to-I2C
adapter is connected to the PC for the first time, Windows is asking for
the USB driver;
where is the driver located?
A: The USB driver is
located in the root directory of the Win-I2CUSBDLL install CD. It is also
located in the
default
HDD installed location: C:\Program Files\The Boardshop\Win-I2CUSB\USBDriver\
Q: What is the current
version of the Win-I2CUSBDLL software and adapter firmware?
A: This can be read from
the "Help-About" screen in the main menu; the adapter must be connected
and detected
to read the firmware version.
Q: Are code examples included
with the Win-I2CUSBDLL kit?
A: Yes, basic examples
are included on the installation CD for the supported enviornments, and
can be downloaded
here:
Win-I2CUSBDLL
Examples (zip Archive)
Q: Does Win-I2CUSBDLL
support 10-bit Addressing?
A: Yes, and the Win-I2CUSB
Universal-Expert Mode can also be used for 10-bit device addressing; Example.
Q: Can the Win-I2CNT/Win-I2CNTDLL
printer port adapter (I2CPort v2.0) be used with the Win-I2CUSBDLL kit?
A: No; the software,
drivers, and DLL included with this kit work only with the included USB-based
I2C adapter.
Q: What connections are
needed between the Win-I2CUSB adapter and a I2C target board?
A: Assuming the target
is independetly powered (3.3v or 5v), only the SDA, SCL, GND connections
are needed.
I2C
pullup resistors for SDA/SCL should be provided on the target board
and the two pullup resistor jumpers
(J_PU)
on the adapter should be removed when connected to the I2C target
board.
Q: Can I power my target
I2C board from the Win-I2CUSB adapter?
A: Yes, but the maximum
5v or 3.3v current supplied to the target I2C board must not exceed 40-50mA,
depending
on the enabled output voltage (3.3v or 5v) from the adapter. Separate
3.3v and 5v stake connectors (2-pin) are
provided
for supplying power to the I2C target board.
Q: What are the differences
between Win-I2CUSB v2.2 and v2.3 hardware adapters?
A: Win-I2CUSB v2.2 adapter
uses a surface-mount USB connector, and v2.3 uses a thru-hole
USB connector.
The
v2.2 and v2.3 adapters are otherwise the same electrically and dimensionally.
Q: What do I do if the
adapter stops working properly?
A: Please email us and
describe the details of the problem you are experiencing: sales@demoboard.com
