The included compact disk (CD) has all the software and drivers necessary to properly operate the
TPA5051EVM with the TI Input USB board. This software is designed to work only with personal
computers (PC). The installation software consists of TPA505x Interface SAA, Command Tool, and .Net
Framework 1.1.
1. Open up the CD, and browse the directory named TPA505x HD GUI Installer.
2. Click on setup.exe. The installer will then initialize.
3. Next, the user must choose the directories in which to install the software. The default directory for the
TPA505x Interface SAA software is C:\Program Files\Texas Instruments Inc\, and the default directory
for the National Instruments™ files is C:\Program Files\National Instruments\. Other directories may be
used, but for purposes of convenience, the default directories are recommended.
4. Once the directory selection has been made, click next to proceed.
5. The National Instruments™ License Agreement appears. It is necessary to read and accept this
agreement to continue with the installation.
6. Once the National Instruments™ License Agreement has been accepted, another window indicating
which components are to be installed appears. It should read Adding or Changing - TPA505x Interface
SAA Files. Click next to proceed.
7. The TPA505x SAA Interface program then installs the necessary files.
8. Once the TPA505x SAA Interface program has been installed, the setup program begins installing
Command Tool 6.0. The Command Tool License Agreement must be read and accepted for
installation to continue.
9. On acceptance of the Command Tool License Agreement, .Net Framework 1.1 is installed. This
installation procedure may take a while. When it is finished, click ok.
10. Command Tool 6.0 proceeds to configure the new software. When it is finished, click Finish.
11. Power up the TI Input USB Board (see the Operation section in this document), and then connect the
USB cable from the computer to the TI Input USB Board. A message pops up stating that the
computer has found new hardware. Shortly after that message appears, the computer finds and installs
the correct drivers for it.
The TPA5051 software graphical user interface (GUI) is designed to allow the user to control the TPA5051
by an I
2
C bus.
1. Select the I
2
C address of the EVM by entering the address number under the I2C Address (0-7)
section. The default for the program is 0. The default for the EVM is also 0. The number in the program
corresponds to the last three digits of the I
2
C address of the device (ADD2, ADD1, and ADD0), which
can be controlled by installing or removing jumpers J5, J4, or J3.
2. Select the mode of operation by clicking on the appropriate circle under Stream Type.
3. The right and left delays can be adjusted by turning the knob to the desired number of delay samples,
or simply entering the number in the box provided (see
). The maximum number of delay
samples per channel for the TPA5051 is 4095. The TPA505x software, however, allows for
programming up to 8191 samples per channel. This is because the software is designed to work for
both the TPA5050 and TPA5051. A delay set above 4095 samples is not valid for the TPA5051.
4. The right and left delays can be tied together by clicking on the R Track L 1 OFF/ON box to the right of
the Right Delay knob.
