C signals can be detected on the SDA and SCL pins.
If they cannot, check the connection between the evaluation
board and the USB module. When trying to run the ISL76534
evaluation software, the occurrence of: “Run-time error number
'429': Active X component can't create object” means that your
computer does not have a sufficiently updated copy of
Microsoft.NET Framework. Microsoft.NET Framework can be
downloaded from the Microsoft web site at:
http://www.microsoft.com/net/download.aspx. Any version
from 2.0 and higher will work.
USB Driver Troubleshooting
The evaluation board software should be able to communicate
with the evaluation board as soon as it is launched. If there is a
communication problem, the dialog box shown in
Figure 10
is
displayed. Click Retry to attempt to reconnect, or click Cancel to
exit the application.
After rebooting the PC, verify that the following files are in the
following locations:
• ISL76534.exe in C:\Program Files\Intersil\ISL76534
• isilhid.dll in C:\Program Files\Intersil\ISL76534
If the dialog shown in
Figure 10
persists, open the Windows
Control Panel. Double-click the System icon, select the Hardware
tab, and then click Device Manager. The Device Manager window
shown in
Figure 11
opens.
Click Human Interface Devices to expand the folder. You should
see HID-compliant Device and an extra USB Human Interface
Device subcategory when the USB module is plugged in. This
indicates the driver is properly installed and is communicating
with the evaluation board.
To verify that the new entries are actually the USB module,
right-click on HID-compliant Device and in the drop-down menu,
click Properties. The HID-compliant device Properties window
opens (
Figure 12
). Click the Details tab. In the text window, you
should see a string, “HID\VID_09AA and PID_2019”
corresponding to the Vendor ID and Product ID of the USB
module. The Vendor ID = 0x09AA, and the Product ID = 0x2019.
