Dual onboard microphones and line inputs for ADC evaluation Connection points for external control and digital audio signals for quick connection to other circuits/input devices. The TLV320ADC3101-K is a complete evaluation kit, which includes a universal serial bus (USB)-based motherboard and evaluation software for use with a personal computer running the Microsoft Windows™ operating system (Windows 2000 or Windows XP™). 1.2 Introduction The TLV320ADC3101EVM is in the Texas Instruments (TI) modular EVM form factor, which allows direct evaluation of the device performance and operating characteristics and eases software development and system prototyping. The TLV320ADC3101-K is a complete evaluation/demonstration kit, which includes a USB-based motherboard, called the USB-MODEVM interface board, and evaluation software for use with a personal computer (PC) running the Microsoft Windows operating system. The TLV320ADC3101-K is operational with one USB cable connection to a PC. The USB connection provides power, control, and streaming audio data to the EVM for reduced setup and configuration. The EVM also provides interfaces for external control signals, audio data, and power. This allows for the TLV320ADC3101 to be connected to the rest of a user development system. 2 EVM Description and Basics This section provides information on the analog input and output, digital control, power, and general connection of the TLV320ADC3101-K. 2.1 TLV320ADC3101-K Block Diagram The TLV320ADC3101-K consists of two separate circuit boards, the USB-MODEVM and the TLV320ADC3101EVM. The USB-MODEVM is built around the TAS1020B streaming audio USB controller with an 8051-based core. The motherboard features two positions for modular EVMs, or one double-wide serial modular EVM can be installed. The TLV320ADC3101EVM is one of the double-wide modular EVMs that is designed to work with the USB-MODEVM. The simple diagram of Figure 1 shows how the TLV320ADC3101EVM is connected to the USBMODEVM. The USB-MODEVM interface board is intended to be used in USB mode, where control of the installed EVM is accomplished using the onboard USB controller device. Provision is made, however, for driving all the data buses (I2C, SPI™, I2S™, etc.) externally. The source of these signals is controlled by SW2 on the USB-MODEVM. See Table 1 for details on the switch settings. The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation module or one larger evaluation module. The TLV320ADC3101EVM is designed to fit over both of the smaller evaluation module slots as shown in Figure 1.

The connection details can be found in Appendix A. 2.4 Digital Signal Connections The digital signals (BCLK, WCLK, DOUT, and MCLK) can be monitored via J5. If external digital signals are connected to the EVM, these digital inputs must be connected via J14 on the USB-MODEVM, and the SW2 switch must be changed accordingly (see Section 2.2.1). The connector details are available in Section A.2. 2.5 Power Connections The TLV320ADC3101EVM can be powered independently when being used in stand-alone operation or by the USB-MODEVM when it is plugged onto the motherboard. 6 TLV320ADC3101-K SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated TLV320ADC3101-K Setup and Installation www.ti.com 2.5.1 Stand-Alone Operation When used as a stand-alone EVM, power is applied to J3 directly, making sure to reference the supplies to the appropriate grounds on that connector. CAUTION Verify that all power supplies are within the safe operating limits shown on the TLV320ADC3101 data sheet before applying power to the EVM. J3 provides connection to the common power bus for the TLV320ADC3101EVM. Power is supplied on the pins listed in Table 7. The TLV320ADC3101-K motherboard (the USB-MODEVM interface board) supplies power to J3 of the TLV320ADC3101EVM. Power for the motherboard is supplied either through its USB connection or via terminal blocks on that board. 2.5.2 USB-MODEVM Operation The USB-MODEVM interface board can be powered from several different sources: • USB • 6-Vdc to 10-Vdc AC/DC external wall supply (not included) • Laboratory power supply When powered from the USB connection, JMP6 must have a shunt from pins 1–2 (this is the default factory configuration). When powered from a 6-Vdc to 10-Vdc power supply, either through the J8 terminal block or J9 barrel jack, JMP6 must have a shunt installed on pins 2–3. If power is applied in any of these ways, onboard regulators generate the required supply voltages, and no further power supplies are necessary. If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM Interface, JMP6 must have no shunt installed. Voltages are then applied to J2 (+5VA), J3 (+5VD), J4 (+1.8VD), and J5 (+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard regulators from the +5VD supply; to enable this configuration, the switches on SW1 must be set to enable the regulators by placing them in the ON position (lower position, looking at the board with text reading right-side up). If +1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placing SW1 switches in the OFF position. Each power-supply voltage has an LED (D1–D7) that lights when the power supplies are active. 3 TLV320ADC3101-K Setup and Installation The following section provides information on using the TLV320ADC3101-K, including setup, program installation, and program usage.

For best results use Processing Block PRB_R2 as this works well with the default EVM setup. 2. Step 2: Specify the Sample Rate – This is a key design parameter input to the Biquad Filter Tool. The default is 44.1 kHz which is the sample rate used on the USB interface for the EVM. The tool works with any sample rate from 8 kHz to 96 kHz; however, if a sample rate other than 44.1 kHz is selected, then the user must go to the clock panel and modify PLL and/or clock settings so that the desired sample rate is set correctly. 3. Step 3: Specify the Biquad Filters – Select the filter type and subtype and enter any required parameters. Note that the parameters not used will be grayed out. Using the Plot check-box, select the filters to plot and/or download. 4. Step 4: Calculate the Coefficients – Click on the Calculate Coefficients OK button. This calculates all the selected filters and plots the combined response of all the checked filters. If a filter is not checked, it is treated as an All-Pass filter. 5. Step 5: Inspect the Plots – Based on the selected filters determine if this is the total desired response. Also, inspect the Scale (dB) display. Some filters may create an overall negative gain error which is reflected in the Scale. For example, if the Scale displays 0.5 then there is a –0.5-dB gain error which can be corrected in the analog PGA or the digital volume. In the last column, the stability of the filter is indicated. If the roots of the filter denominator are less than 1, then the filter is stable and this field will display the text "Stable". Otherwise, it will display the text "Unstable," meaning that the unstable filter should be re-specified until it is stable. 6. Step 6: Download the Coefficients – Click the Download Coefficients OK button. This action downloads the filter coefficients to the TLV320ADC3101 device. Note that the process of downloading coefficients is accomplished by the following register writes to the device: • Page 0 - Select processing block and power down both ADCs • Page 4 - Write filter coefficients to both left and right channels as required • Page 0 - Power up both ADCs Note that the filter coefficients can be saved as an I2C script by using the Command-line Interface Record button. The I2C commands will be displayed in the Command Buffer (Figure 14),which can be selected and copied to a text command file.

Command-line Interface Panel Record Function 4.2 Status Flags Panel The TLV320ADC3101 status flags can monitored in the Status Flags panel (Figure 15) which is located below the Panel Selection Tree. Pressing the POLLING button continuously reads all the registers relevant to each flag and updates those flags accordingly. The rate at which the registers are read can be modified by changing the value in the Polling Interval numeric control. Note that a smaller interval reduces responsiveness of other controls, especially volume sliders, due to bandwidth limitations. By default, the polling interval is 200 ms and can be set to a minimum of 20 ms. The Sticky Flags tab contains indicators whose corresponding register contents clear every time a read is performed to that register. To read all the sticky flags, click the Read Sticky Flags button.

Register Tables Panel 4.4 Command-Line Interface Panel The Command-Line Interface panel provides a means to communicate with the TLV320ADC3101 using a simple scripting language (described in Section G.3). The TAS1020B USB Controller (located on the USB-MODEVM motherboard) handles all communication between the PC and the TLV320ADC3101. A script is loaded into the Command Buffer (Figure 17), either by loading a script file using the File menu or by pasting text from the clipboard using the Ctrl-V key combination. When the command buffer is executed, the return data packets that result from each individual command are displayed in the Command History control. This control is an array (with a maximum size of 100 elements) that contains information about each command. The INTERFACE box displays the interface used for a particular command in the Command History array. The COMMAND box displays the type of command executed (i.e., write, read) for a particular interface. The FLAG RETRIES box displays the number of read iterations performed by a Wait for Flag command (see Section G.3 for details). The REGISTER DATA array displays the register number and data bytes that correspond to a particular command. The Information tab provides additional information related to the Command History as well as additional settings. The Syntax and Examples tabs provide useful information related to the scripting language. The File menu provides some options for working with scripts. The first option, Open Script File..., loads a command file script into the command buffer. This script can then be executed by pressing the Execute Command Buffer button. The contents of the Command Buffer can be saved using the Save Script File... option. Both the Command Buffer and Command History can be cleared by clicking their corresponding Clear buttons.

Because the TAS1020B has several routines in its ROM which are designed for use with HID-class devices, HID-like structures are used, even though the USB-MODEVM is not an HID-class device. Data is passed from the PC to the TAS1020B using the control endpoint. Data is sent in a HIDSETREPORT (see Table 10). Table 10. USB Control Endpoint HIDSETREPORT Request Variable Value Description bmRequestType 0x21 00100001 bRequest 0x09 SET_REPORT wValue 0x00 Don't care wIndex 0x03 HID interface is index 3 wLength calculated by host Data Data packet as described in Table 11. The data packet consists of the following bytes, shown in Table 11: Table 11. Data Packet Configuration BYTE NUMBER 0 TYPE DESCRIPTION Interface Specifies serial interface and operation. The two values are logically ORed. Operation: READ WRITE 0x00 0x10 GPIO SPI_16 I2C_FAST I2C_STD SPI_8 0x08 0x04 0x02 0x01 0x00 Interface: 1 I2C slave address Slave address of I2C device or MSB of 16-bit register address for SPI 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 Data Up to 60 data bytes could be written at a time. EP0 maximum length is 64. The return packet is limited to 42 bytes, so advise only sending 32 bytes at any one time. 4..64 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 40 USB-MODEVM Protocol SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated USB-MODEVM Protocol www.ti.com 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 the MSB of the register address. [2]0x02 [3]0xE0 [4]0xAA [5]0x55 In each case, the TAS1020 returns, in an HID interrupt packet, the following: [0] interface byte | status status: REQ_ERROR 0x80 INTF_ERROR 0x40 REQ_DONE 0x20 [1] [2] [3] [4..60] for I2C interfaces, the I2C address as sent for SPI interfaces, the read back-data from SPI line for transmission of the corresponding byte length as sent for I2C interfaces, the register address as sent for SPI interfaces, the read-back data from SPI line for transmission of the corresponding byte echo of data packet sent SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated USB-MODEVM Protocol 41 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 ORed with 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 back as: [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 previously described, 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 42 USB-MODEVM Protocol SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated GPIO Capability www.ti.com 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. G.2 GPIO Capability The USB-MODEVM has seven GPIO lines. Access them by specifying the interface to be 0x08, and then using the standard format for packets—but addresses are unnecessary. The GPIO lines are mapped into one byte (see Table 12): Table 12. GPIO Pin Assignments Bit 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 example was 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 G.3 Writing Scripts 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, except for 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 use r Read from the serial control bus w Write to the serial control bus > Extend repeated write commands to lines below a w # Comment b Break d Delay f Wait for Flag SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated USB-MODEVM Protocol 43 Writing Scripts www.ti.com The first command, I, sets the interface to use for the commands to follow. This command must be followed by one of the following parameters: i2cstd i2cfast spi8 spi16 gpio Standard mode I2C bus Fast mode I2C bus SPI bus with 8-bit register addressing SPI bus with 16-bit register addressing Use the USB-MODEVM GPIO capability For example, if a fast mode I2C bus is to be used, the script begins with: I i2cfast A double quoted string of characters following the b command can be added to provide information to the user about each breakpoint. When the script is executed, the software's command handler halts as soon as 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 the command matches the data being read. If the data does not match, the command handler retries for up to 200 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 format and '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 before proceeding. 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 in hexadecimal, and each byte must be separated by a space. Commands are interpreted and sent to the TAS1020B by the program using the protocol described in Section G.1. The first byte following an r (read) or w (write) command is the I2C slave address of the device (if I2C is used) or the first data byte to write (if SPI is used—note that SPI interfaces are not standardized on protocols, so the meaning of this byte varies with the device being addressed on the SPI bus). The second byte is the starting register address that data will be written to (again, with I2C; SPI varies—see Section G.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 to read, (expressed in hexadecimal). For example, to write the values 0xAA 0x55 to an I2C device with a slave address of 0x30, starting at a register 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 the I2C slave device at address 0x30, writing the values into registers 0x03 and 0x04. The script then reads back two bytes from the same device starting at register address 0x03. Note that the slave device value does not change. It is unnecessary to set the R/W bit for I2C devices in the script; the read or write commands does that. 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 > command follows: #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 44 USB-MODEVM Protocol SLAU267A – December 2008 – Revised October 2012 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated Writing Scripts www.ti.com Any text editor can be used to write these scripts; Jedit is an editor that is highly recommended for general usage. 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 then selecting Open Script File... from the File menu. Locate the script and open it. The script is then displayed in the command buffer. The user can also edit the script once it is in the buffer and save it by selecting Save Script File... from the File menu. Once the script is in the command buffer, it can be executed by pressing the Execute Command Buffer button. If there are breakpoints in the script, the script executes to that point, and the user is presented with a dialog box with a button to press to continue executing the script. When ready to proceed, push that button and the script continues.
