Clicking System Initialization in the Tools menu displays the dialog box shown in
. This dialog
box provides the means for initializing the TVP5154 decoder(s) and/or video encoder for a particular video
mode, as well as programming settings for the DM642 through the Generic I
2
C registers. The details of
the initialization are contained in the command file (with a CMD file extension).
The command file is loaded using the Browse
…
button. Once the command file is opened, a text list
displays descriptions of the individual datasets contained within the command file.
Click once on the desired dataset description to select it. Click the Program Device(s) Using Selected
Dataset button to run the selected dataset, which loads the devices via the I
2
C bus. When the device
initialization has completed, the status indicator reads Ready.
Note:
If Ready does not display, the devices are not initialized and the I
2
C bus is not
communicating. See Chapter 10, Troubleshooting, for possible solutions.
Click the OK button to close the dialog box. Each time the System Initialization dialog box is closed, the
initialization file pathname and the dataset selection number are saved in the Windows registry to allow
these settings to be retained for the next time WinVCC runs.
