I
2
C System Test
WinVCC in Depth
The WinVCC Configuration dialog box (see
) should now be visible. This dialog box configures
the I
2
C bus on the TVP5154EVM. All settings from this dialog box are stored in the Windows registry and
are restored the next time the program is started. After initial installation, VID_DEC is set to TVP5154 and
VID_ENC is set to 7311 Encoder.
The I
2
C slave address for each device must match the I
2
C slave address selected by jumpers on the
TVP5154EVM. These jumpers are set by the factory to use 0xB8 for the TVP5154 and 0x54 for the
Encoder. It is also important to select the correct Specific Device type for the video decoder. TVP5154 and
7311 Encoder must be selected for this EVM.
All Program Options must be enabled. Disabling these options is only required if debugging a problem
with the I
2
C bus.
Clicking OK begins I
2
C communication with the selected devices.

C Address Configuration
The I
2
C system test of selected registers runs immediately after closing the WinVCC Configuration dialog
box with OK (unless the I
2
C system test program options button was disabled).
If the I
2
C system test passes, only a PASS message appears. If the test failed, a dialog box like the one
shown in
appears. See Section 10, Troubleshooting, for details on how to resolve this issue.
