Software Installation

The system comes with the anti-alias filters bypassed. To connect the filters, you must rotate the appropriate jumpers (JP1–JP8) as described in section 2.3.

The I2C slave address can be selected with jumpers JP9 and JP10. There are four possible addresses: B8, BA, BC, and BE. The default setting for these jumpers is for the shunt to short pins 2-3, which selects 0xB8. These are connected to pins 117 and 118, which are read at power up. If you move both the jumpers to positions 1-2 and reset the board, the video decoder now responds to I2C slave address 0xBE. If you choose to change the address, you must exit, restart WinVCC, and configure the software to use the new I2C slave address.

6Software Installation

WinVCC is a Windows application that uses the PC parallel port to emulate I2C, providing access to each device on the I2C bus. WinVCC makes use of CMD files, a text editable file that allows preset video setups to be programmed easily.

This feature allows the user to easily set multiple I2C registers with the press of a button. WinVCC also has property sheets for the TVP5154, which allows the user to control the I2C registers with a GUI.

All necessary software for the TVP5154EVM is provided on the enclosed CD. Perform the following steps to install WinVCC:

1.Explore the provided TVP5154EVM Software CD.

2.Install Port95NT.exe. This is the parallel port driver used by WinVCC. This driver must be installed and the PC must be rebooted before WinVCC operates correctly. This does not affect normal parallel port operation.

3.Install Setup.exe. Click Next at all prompts and click Finish to complete the installation process. This installs WinVCC onto the PC. No reboot is required.

4.Run WinVCC.exe.

Note: A shortcut to WinVCC should now be available on the desktop. WinVCC and additional TVP5154-related documentation can also be found at Start→Programs→TVP5154EVM Software.

7WinVCC Quick Start

Perform the following steps in order to see a video output from the TVP5154EVM.

1.Once WinVCC is executed, the WinVCC Configuration screen appears, as shown in Figure 4. This dialog box configures the I2C bus. Next to VID_DEC, select the TVP5154 and ensure the I2C address is set to 0xB8 (default setting on EVM.) This must match the I2C ADDR jumper on the TVP5154 board.

2.Next to VID_ENC, select the 7311 Encoder and ensure the I2C address is set to 0x54 (default setting on EVM.) This must match the I2C ADDR jumper on the encoder board.

Note: If WinVCC is running and the TVP5154 or encoder board I2C address is changed, power must be cycled on the EVM.
