Preface SBAU174 – June 2010 Read This First About This Manual This user’s guide describes the operation of the Texas Instruments CodecControl software for the PCM9211EVM. CodecControl provides a graphical user interface (GUI) for supported TI audio codecs. The software is compatible with Microsoft® Windows® XP, Vista, and Windows 7. For a more detailed description of the PCM9211 product line, refer to the product data sheet available from the Texas Instruments web site at http://www.ti.com/.

Chapter 1 SBAU174 – June 2010 Description The PCM9211EVM is an evaluation board for the PCM9211, a 216-kHz digital audio interface transceiver (DIX) with stereo analog-to-digital conversion and routing. This EVM provides all necessary connectors and circuitry for interfacing to audio test systems and commercial audio equipment. 1.
Getting Started 1.3 www.ti.com Getting Started To get started with the PCM9211EVM, perform the following steps: Step 1. Install the CodecControl software (see Chapter 2) Step 2. Launch the CodecControl software. Step 3. Plug a digital audio source into the coaxial S/PDIF input (J5). Step 4. Plug a analog audio source (line level) into the analog input (J2). Step 5. Connect the EVM to the PC via a mini USB-B to USB-A cable.

Chapter 2 SBAU174 – June 2010 CodecControl Software The CodecControl software is intended to facilitate user evaluation of TI audio codecs. It includes a script interpreter, an interactive device block diagram-based GUI, a register inspector, and supplemental features depending on the specific codec capabilities. This chapter explains how to use the CodecControl software together with a TI audio codec EVM. 2.
EVM Window www.ti.com If no TI audio codec EVM is connected to the PC, the control software also supports an EVM simulation mode, where it is possible to retrieve script commands based on user input within the block diagram. Simulation mode is only available if no TI audio codec EVM is attached to the PC. Choose File->New EVM simulation… and select an EVM from the list of supported TI audio codec EVMs. 2.
EVM Window www.ti.com 2.4.1 Using Active Objects Moving the mouse pointer over an active object highlights the active object; as noted, the object turns red. For example, the MPIO_A active object changes from its inactive state to its active state when the mouse pointer enters the amplifier symbol, as Figure 2-2 shows. Object in Inactive State Object in Active State Figure 2-2.
Dialogs and Active Objects 2.5 www.ti.com Dialogs and Active Objects The CodecControl software contains several dialog windows that provide access to additional features. Most dialogs are linked to active objects and are opened by clicking on the active object. Several dialogs are not linked to active objects and are opened instead using the View menu. 2.5.1 Command Dialog Open the command dialog (View->Command…) to write, edit, load, save, and run command scripts.
Dialogs and Active Objects www.ti.com 2.5.3 Register Inspector The register inspector dialog (View->Register Inspector…) gives access to all registers of the TI audio codec. Figure 2-5 illustrates the register inspector dialog. Figure 2-5. Register Inspector The register inspector displays the content of the connected TI audio codec device registers. To trigger reading the content of one page, click the Refresh button. • The addr column shows the address of the registers in decimal notation.

is the device address in hexadecimal format. For example, 30 for device address 0x30. is the register in hexadecimal format that will be read from. is the number of bytes that will be read from in auto-increment mode.EVM Applications www.ti.com 2.6 EVM Applications The PCM9211EVM contains an EEPROM that can store EVM applications; for example: • Initialization scripts • Parameter patch scripts The CodecControl software also contains a browser to access the applications stored in the EEPROM. To access the browser, select File->EVM Applications…. Figure 2-6 illustrates the EVM Applications window. Figure 2-6. EVM Applications Applications stored in the EEPROM are shown in a tree view.
Firmware update www.ti.com Some TI audio codecs have on or more pushbuttons that select an application or a script within an application. Click the Update EVM button to program the EEPROM. Scripts are stored in a compiled binary format on the EEPROM and cannot be read back. A red lock next to the application name highlights scripts that reside in the EEPROM but cannot be viewed in the command window.
