Q: Where do I get
the
latest Win-I2CUSBDLL Software Updates?
A: Win-I2CUSBDLL
v5.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 7?
A: Win-I2CUSBDLL v5
supports Windows-XP/Visa/7 (32bit and 64bit). D/L latest version
from our Updates Page.
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 older Windows computer?
A: The latest
software
v5 supports Win-XP and newer Windows operating
systems.
The
latest
v5
software does not support Win-2000, Win-NT, 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
was just 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: 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 (v2.2-v2.3) and on the PCB
(v3.1) hardware adapters.
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 \Documentation directory of the Win-I2CUSBDLL v5
instllation CD included with the kit.
It is also
located in the
default
HDD installed location: C:\Program Files\The
Boardshop\Win-I2CUSB\USBDriver\
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 Win-I2CUSBDLL 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/v2.3 and v3.1 hardware adapters?
A: Win-I2CUSB v2.2
adapter
uses a surface-mount USB connector, and v2.3 uses a
thru-hole
USB connector.
The
newest v3.1 adapters use a newer design/architecture, but share the
same connector configuration and
PCB dimensions as the earlier v2.x Win-I2CUSB
adapters.
Note: Win-I2CUSB v3.1 adapters require the latest
Win-I2CUSB/DLL v5 software/drivers; download from our Updates
Page.
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
