Frequently Asked Questions for Win-I2CUSBDLL:

Q: Can I get the current  DLL User's Manual that is included with the kit?
A: Win-I2CUSBDLL(v4-v5) - DLL User's Manual

Q: Can I get the latest Win-I2CUSB Software Installation Guide and Software Manual that are included with the kit?
A:  Win-I2CUSBDLL (v5) -  Installation & Hardware Manual      Software User's Manual

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:
