2.2 Control Software

2.3 Installation

2.4 Concepts

EVM + PC www.ti.com

The TSC2117 control software exposes most features of the TSC2117 through an intuitive graphical userinterface.

Note: Before Windows on the PC can use the TSC2117EVM-K as a sound card, the TSC2117 onthe EVM must be configured (sampling rate, audio routing, internal amplifier settings etc.)with the TSC2117 control software.

Download the TSC2117 control software (SLAC264) from the TSC2117 product folder at http://www.ti.comand launch the program (SLAC264).

This file is a self-extracting archive. The default target folder is:

C:\Program Files\Texas Instruments\TSC2117Click the Unzip button to complete the installation.

The TSC2117 control software is now available in the target folder. The name of the executable isTSC2117.exe

To launch the TSC2117 control software, navigate to the target folder with the Windows Explorer anddouble click TSC2117.exe.

The TSC2117 control software presents a block diagram view of the TSC2117 (or select modules withinthe TSC2117).

The block diagram consists of active objects that can react to user input (for example switches oramplifiers with variable gain that show a volume control on a mouse click event).

Note: Each active object will change color to red if the mouse cursor is above the object. Clickingthe object will trigger its function.

Some active objects are linked to control register(s) of the TSC2117 in a two way fashion. If an EVM isconnected, the control software will update the appropriate register(s) whenever an active object istriggered. If a register that is linked to an active object is changed via other components (for example thescript interpreter or the register inspector), the active object will change its state accordingly.

The control software will automatically detect a TSC2117EVM-K once it is connected to a USB port of thePC.

If no TSC2117EVM-K is connected to the PC, the control software changes to a simulation mode, where itis possible to retrieve script commands based on user input within the block diagram.

Figure 2. Main Window

At the top of the main window is a tool bar with buttons to change between four different use cases of theTSC2117:

By default, the control software displays the full featured block diagram of the TSC2117.

Each use case has its own initialization script, which will run if a use case is selected by clicking on one ofthe use case buttons. The initialization script contains register settings for the TSC2117 to configure thedevice for a specific use case.

The toolbar contains a control that determines the zoom factor. Change the zoom by selecting the desiredzoom factor.

To move the block diagram, click on a blank area within the block diagram and drag the diagram with themouse.

At the bottom of the main window is a status bar that provides information about the state of thecommunication between the control software and the TSC2117EVM-K. It also shows hints about elementsin the block diagram, for example the I2C page and register / bit location of a selected switch.

Audio signal paths (both digital and analog) will change color from black to• Blue for left audio output• Turquoise for right audio output



2.5.1 Using Active Objects

2.6 Dialogs and Active Objects

EVM + PC www.ti.com

• Magenta for audio input

once they are activated via switches. This feature visualizes all audio paths and immediately highlights if apath is disabled.

Moving the mouse pointer over an active object will light up the active object (the color of the object turnsred).

For example, the Class-A/B HP Driver left amplifier active object will turn from its inactive state to its activestate when the mouse pointer enters the amplifier symbol:

Clicking the activated object will trigger its function. In the case of the amplifier active object, the functionis a volume control. Moving the volume control slider changes the volume setting of the amplifier (it is alsopossible to change the volume by clicking onto the number within the amplifier symbol and typing the newgain setting).The control software updates the appropriate register in the TSC2117 and as a result thevolume on the headphone output will change accordingly.

The TSC2117 control software contains several dialog windows that give access to additional features.

Most dialogs are linked to active objects and are opened by clicking on the active object.

A few dialogs are not linked to active objects and are opened using the View menu.

6 TSC2117EVM-K SLAU282–April 2009Submit Documentation Feedback


2.6.1 Init Script Dialog

TSC2117EVM-K is detected or if the user selects another use case.

To show or edit the initialization script, choose View->Init Script… from the main window menu bar.

Figure 3. Initialization Script

Click the Run button to run the script again. For further information about the script syntax, see Figure 3.



2.6.2 Command Dialog

EVM + PC www.ti.com

Open the command dialog (View->Command…) to write, edit, load, save and run command scripts.Command scripts are text files that contain commands to communicate with the TSC2117. The syntax isdescribed in Figure 4.

Figure 4. Command Dialog

• The main area of the command dialog is command buffer (editable text) which contains the commandscript. To run the command script, click the Run button.

• The smaller read only text area on the right side of the command dialog displays control data readfrom the TSC2117. The Clear button clears the Read Data field.

• The one line text edit field on the left bottom allows single command execution.• The Record check box enables recording of commands generated by the control software.

Figure 4 shows a recording of the volume control for the left Class-A/B HP Driver amplifier (note that theRecord checkbox is checked).

A single command to read four bytes starting at address 0x28 was executed and the result is displayed inthe Read Data field.



2.6.3 Register Inspector

www.ti.com EVM + PC

The register inspector dialog (View->Register Inspector…) gives access to all registers of the TSC2117.

Figure 5. Register Inspector

The register inspector displays the content of the TSC2117 registers. The control software will read allTSC2117 registers when a TSC2117EVM-K is detected. To force reading the content of one page, clickthe Refresh button.• The Page edit field selects the page to be displayed.• The addr column shows the address of the registers within the selected page in decimal notation.• The description column contains a description for each register. If the register has no function

assigned, it is declared Reserved.• The data columns show the data of each register (one byte). The first data column uses decimal

notation, the second uses hexadecimal notation. It is possible to change the register value by clickinginto one of the data fields and typing the new value (either decimal or hexadecimal).

• The numbered columns show the register content in binary notation. Read/Write bits are shown solidblack or red; read only bits are gray or dark red. Red numbers represent bits that recently changed. Tochange a single writeable bit, click on the bit and it will flip.



2.6.4 DAC Filter

EVM + PC www.ti.com

One of the digital signal processing blocks of the TSC2117 implements five digital biquad filters. The DACdigital filter dialog (View->DAC Filter…) allows real time graphical manipulation of the digital filters.

The control software will automatically configure the digital signal processing block when the DAC digitalfilter dialog is opened.

The digital filter dialog limits the range of each digital biquad filter to +/-12[dB] (this is an arbitrary limitationfor demonstration purposes).• Each biquad has its own unique handle with a unique color. Each handle will light up white if the

mouse pointer is in the vicinity, showing that it can be selected. To change the frequency and gain of abiquad, grab and drag its handle.It is also possible to change the gain using the slider for each biquad.

• Each biquad can be configured for parametric EQ, Shelf Treble or Shelf Bass. If it is configured for EQ,press the shift key before selecting the handle to adjust the bandwidth of the EQ using the mousepointer.

• Due to digital range limitations, the biquads will automatically scale, if the biquad coefficients exceedthe limitations.The coordinate system will shift accordingly to reflect the resulting attenuation.

• To avoid clipping, add additional attenuation with the Attenuate slider.• To retrieve the biquad coefficients, open the command dialog (see 0) and check Record.



2.6.5 Clock and Digital Signal Routing

www.ti.com EVM + PC

The TSC2117 has a flexible and complex clock and digital signal routing architecture.

Two processors can connect to the TSC2117 using two separate I2S™ interfaces: The primary I2Sinterface has dedicated pins whereas the secondary I2S interface signals can be assigned to a selectionof pins.

The TSC2117 has an on-chip clock generation module which can be configured to generate the samplingrate, modulator clocks, converter clocks, bit clock and word clock.

Click on the “Digital Audio Processing Serial Interface” active object (if it is not within the current scope ofthe main window, drag the block diagram to the left until the active object appears). This will change theblock diagram to the clock and digital signal routing diagram:

Figure 6. Clock and Digital Signal Routing

The clock and digital signal routing diagram shows the current state of the TSC2117 routing configurationand allows interactive manipulation.• Each clock or signal source has its own unique color. For example, the BCLK signal from the internal

clock generation module has a turquoise color.• To trace the routing of a specific signal, follow its color. The example in Figure 6 shows that the BCLK

signal from the internal clock generation module is routed to the primary I2C™ BCLK pin (which isconfigured as an output), to the secondary I2S BCLK signal (which is not connected to a pin) and tothe BCLK input of the codec (ADC and DAC within the TSC2117).

• To change the definition of a pin (input or output), click the active object (arrow) that belongs to the pin.Only pins that can change between input and output are linked to such an active object. The clockrouting diagram will automatically change to reflect the new routing.

• Some of the switches within the diagram are active objects, which can be manipulated using themouse pointer. Other switches open or close depending on the state of the associated pin.

• To assign a pin to a signal of the secondary I2S interface, choose one of the available pins in the dropdown box that belongs to the signal. The list of available pins will change automatically depending onthe assignment of other signals to pins.

• Click on the “Back To Codec” active object to return to the previous block diagram.• Click on the “Internal Clock Gen Module” active object to display the digital configuration dialog.



2.6.6 Digital Configuration

Appendix C USB-MODEVM Protocol

C.1 USB-MODEVM Protocol

Appendix C www.ti.com

The USB-MODEVM is defined to be a Vendor-Specific class and is identified on the PC system as anNI-VISA device. Because the TAS1020B has several routines in its ROM which are designed for use withHID-class devices, HID-like structures are used, even though the USB-MODEVM is not an HID-classdevice. Data is passed from the PC to the TAS1020B using the control endpoint.

Data is sent in a HIDSETREPORT (see Table C-1).

Table C-1. USB Control EndpointHIDSETREPORT Request

Part Value DescriptionbmRequestType 0x21 00100001bRequest 0x09 SET_REPORTwValue 0x00 don't carewIndex 0x03 HID interface is index 3wLength calculated by hostData Data packet as described in Table C-2.

The data packet consists of the following bytes, shown in Table C-2:

Table C-2. Data Packet ConfigurationBYTE NUMBER TYPE DESCRIPTION

0 Interface Specifies serial interface and operation. The two values are logically ORed.Operation:

READ 0x00WRITE 0x10

Interface:GPIO 0x08SPI_16 0x04I2C_FAST 0x02I2C_STD 0x01SPI_8 0x00

1 I2C Slave Slave address of I2C device or MSB of 16-bit reg addr for SPIAddress

2 Length Length of data to write/read (number of bytes)3 Register address Address of register for I2C or 8-bit SPI; LSB of 16-bit address for SPI

4..64 Data Up to 60 data bytes could be written at a time. EP0 maximum length is 64. The returnpacket is limited to 42 bytes, so advise only sending 32 bytes at any one time.

Example usage:Write two bytes (AA, 55) to device starting at register 5 of an I2C device with address A0:

[0] 0x11[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

28 USB-MODEVM Protocol SLAU282–April 2009Submit Documentation Feedback


www.ti.com USB-MODEVM Protocol

Do the same with a fast mode I2C device:

[0] 0x12[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

Now with an SPI device which uses an 8-bit register address:

[0] 0x10[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

Now, do a 16-bit register address, as found on parts like the TSC2101. Assume the register address(command word) is 0x10E0:

[0] 0x14[1] 0x10 → Note: the I2C address now serves as MSB of reg addr.[2] 0x02[3] 0xE0[4] 0xAA[5] 0x55

In each case, the TAS1020 returns, in an HID interrupt packet, the following:

[0] interface byte | statusstatus:

REQ_ERROR 0x80

INTF_ERROR 0x40

REQ_DONE 0x20

[1] for I2C interfaces, the I2C address as sentfor SPI interfaces, the read back data from SPI line for transmission of the corresponding byte

[2] length as sent[3] for I2C interfaces, the reg address as sent

for SPI interfaces, the read back data from SPI line for transmission of the corresponding byte[4..60] echo of data packet sent

USB-MODEVM Protocol www.ti.com

If the command is sent with no problem, the returning byte [0] is the same as the sent one logically ORedwith 0x20 - in the preceding first example, the returning packet is:

[0] 0x31[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

If for some reason the interface fails (for example, the I2C device does not acknowledge), it comes backas:

[0] 0x51 → interface | INTF_ERROR[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

If the request is malformed, that is, the interface byte (byte [0]) takes on a value which is not as previouslydescribed, the return packet is:

[0] 0x93 → the user sent 0x13, which is not valid, so 0x93 returned[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

The preceding examples used writes. Reading is similar:Read two bytes from device starting at register 5 of an I2C device with address A0:

[0] 0x01[1] 0xA0[2] 0x02[3] 0x05

C.2 GPIO Capability

C.3 Writing Scripts

www.ti.com GPIO Capability

The return packet is:

[0] 0x21[1] 0xA0[2] 0x02[3] 0x05[4] 0xAA[5] 0x55

assuming that the values written starting at Register 5 were actually written to the device.

The USB-MODEVM has seven GPIO lines. Access them by specifying the interface to be 0x08, and thenusing the standard format for packets—but addresses are unnecessary. The GPIO lines are mapped intoone byte (see Table C-3):

Table C-3. GPIO Pin AssignmentsBit 7 6 5 4 3 2 1 0

x P3.5 P3.4 P3.3 P1.3 P1.2 P1.1 P1.0

Example: write P3.5 to a 1, set all others to 0:

[0] 0x18 → write, GPIO[1] 0x00 → this value is ignored[2] 0x01 → length - ALWAYS a 1[3] 0x00 → this value is ignored[4] 0x40 → 01000000

The user can also read back from the GPIO to see the state of the pins. Assume the previous examplewas just written to the port pins.

Example: read the GPIO

[0] 0x08 → read, GPIO[1] 0x00 → this value is ignored[2] 0x01 → length - ALWAYS a 1[3] 0x00 → this value is ignored

The return packet is:

[0] 0x28[1] 0x00[2] 0x01[3] 0x00[4] 0x40

A script is simply a text file that contains data to send to the serial control buses.

Each line in a script file is one command. No provision is made for extending lines beyond one line, exceptfor the > command. A line is terminated by a carriage return.

The first character of a line is the command. Commands are:

i Set interface bus to user Read from the serial control busw Write to the serial control bus> Extend repeated write commands to lines below a w# Commentb Breakd Delay

f Wait for Flag



Writing Scripts www.ti.com

The first command, i, sets the interface to use for the commands to follow. This command must befollowed by one of the following parameters:

i2cstd Standard mode I2C busi2cfast Fast mode I2C busspi8 SPI bus with 8-bit register addressingspi16 SPI bus with 16-bit register addressinggpio Use the USB-MODEVM GPIO capability

For example, if a fast mode I2C bus is to be used, the script begins with:

i i2cfastA double quoted string of characters following the b command can be added to provide information to theuser about each breakpoint. When the script is executed, the software's command handler halts as soonas a breakpoint is detected and displays the string of characters within the double quotes.

The Wait for Flag command, f, reads a specified register and verifies if the bitmap provided with thecommand matches the data being read. If the data does not match, the command handler retries for up to200 times. This feature is useful when switching buffers in parts that support the adaptive filtering mode.The command f syntax follows:f [i2c address] [register] [D7][D6][D5][D4][D3][D2][D1][D0]

where 'i2c address' and 'register' are in hexadecimal formatand 'D7' through 'D0' are in binary format with values of 0,1 or X for don't care.

Anything following a comment command # is ignored by the parser, provided that it is on the same line.

The delay command d allows the user to specify a time, in milliseconds, that the script pauses beforeproceeding. The delay time is entered in decimal format.A series of byte values follows either a read or write command. Each byte value is expressed inhexadecimal, and each byte must be separated by a space. Commands are interpreted and sent to theTAS1020B by the program using the protocol described in Section C.1.

The first byte following an r (read) or w (write) command is the I2C slave address of the device (if I2C isused) or the first data byte to write (if SPI is used—note that SPI interfaces are not standardized onprotocols, so the meaning of this byte varies with the device being addressed on the SPI bus). Thesecond byte is the starting register address that data will be written to (again, with I2C; SPI varies—seeSection C.1 for additional information about what variations may be necessary for a particular SPI mode).Following these two bytes are data, if writing; if reading, the third byte value is the number of bytes toread, (expressed in hexadecimal).

For example, to write the values 0xAA 0x55 to an I2C device with a slave address of 0x30, starting at aregister address of 0x03, the user writes:#example script

i i2cfast

w 30 03 AA 55

r 30 03 02

This script begins with a comment, specifies that a fast I2C bus will be used, then writes 0xAA 0x55 to theI2C slave device at address 0x30, writing the values into registers 0x03 and 0x04. The script then readsback two bytes from the same device starting at register address 0x03. Note that the slave device valuedoes not change. It is unnecessary to set the R/W bit for I2C devices in the script; the read or writecommands does that.

www.ti.com Writing Scripts

If extensive repeated write commands are sent and commenting is desired for a group of bytes, the >command can be used to extend the bytes to other lines that follow. A usage example for the > commandfollows:#example script for '>' command

i i2cfast

# Write AA and BB to registers 3 and 4, respectively

w 30 03 AA BB

# Write CC, DD, EE and FF to registers 5, 6, 7 and 8, respectively

> CC DD EE FF

# Place a commented breakpoint

b "AA BB CC DD EE FF was written, starting at register 3"

# Read back all six registers, starting at register 3

r 30 03 06

The following example demonstrates usage of the Wait for Flag command, f:#example script for 'wait for flag' command

i i2cfast

# Switch to Page 44

w 30 00 2C

# Switch buffers

w 30 01 05

# Wait for bit D0 to clear. 'x' denotes a don't care.

f 30 01 xxxxxxx0

Any text editor can be used to write these scripts; Jedit is an editor that is highly recommended for generalusage. For more information, go to: http://www.jedit.org.

Once the script is written, it can be used in the command window by running the program, and thenselecting Open Script File... from the File menu. Locate the script and open it. The script is then displayedin the command buffer. The user can also edit the script once it is in the buffer and save it by selectingSave Script File... from the File menu.

Once the script is in the command buffer, it can be executed by pressing the Execute Command Bufferbutton. If there are breakpoints in the script, the script executes to that point, and the user is presentedwith a dialog box with a button to press to continue executing the script. When ready to proceed, push thatbutton and the script continues.
