∙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 6 Vdc-10 Vdc, 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 need to 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.
3TLV320AIC3107EVM-K Setup and Installation
The following section provides information on using the TLV320AIC3107EVM-K, including set up, program installation, and program usage.
Note: If using the EVM in stand-alone mode, the software must be installed per the following instructions, but the hardware configuration may be different.
3.1Software Installation
1.Locate the installation file on the CD-ROM included with the EVM or download the latest version of the software located on the AIC3107 Product Page.
2.Unzip the installation file by clicking on the self-extracting zip file.
3.Install the EVM software by double-clicking the Setup executable and follow the directions. Users may be prompted to restart their computers.
This installs all the TLV320AIC3107 software and required drivers onto the PC.
3.2EVM Connections
1.Ensure that the TLV320AIC3107EVM is installed on the USB-MODEVM Interface board, aligning J1, J2, J3, J4, and J5 with the corresponding connectors on the USB-MODEVM.
2.Verify that the jumpers and switches are in their default conditions.
3.Attach a USB cable from the PC to the USB-MODEVM Interface board. The default configuration provides power, control signals, and streaming audio via the USB interface from the PC. On the USB-MODEVM, LEDs D3-6 light to indicate the power is being supplied from the USB.
4.For the first connection, the PC recognizes new hardware and begins an initialization process. The user may be prompted to identify the location of the drivers or allow the PC to automatically search for them. Allow the automatic detection option.
5.Once the PC confirms that the hardware is operational, D2 on the USB-MODEVM lights to indicate that the firmware has been loaded and the EVM is ready for use. If the LED is not lighted, verify that the drivers were installed, try to unplug, and restart at Step 3.
After the TLV320AIC3107EVM-K software installation (described in Section 3.2) is complete, evaluation and development using the target TLV320AIC3107 can begin.
The TLV320AIC3107EVM software now can be launched. The user sees an initial screen that looks similar to Figure 4.
