TLV320AIC3107EVM-K Setup and Installation
•
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.
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.
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.
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
