WinVCC in Depth
8.2WinVCC Configuration Dialog Box
The WinVCC Configuration dialog box (see Figure 10) should now be visible. This dialog box configures the I2C 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 I2C slave address for each device must match the I2C 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 I2C bus.
Clicking OK begins I2C communication with the selected devices.

8.3I2C System Test
The I2C system test of selected registers runs immediately after closing the WinVCC Configuration dialog box with OK (unless the I2C system test program options button was disabled).
If the I2C system test passes, only a PASS message appears. If the test failed, a dialog box like the one shown in Figure 11 appears. See Section 10, Troubleshooting, for details on how to resolve this issue.
