An on-board AIC32 codec allows the DSP to transmit and receive analog audio
signals. The I
the audio stream. Signal interfacing is done through 3.5mm audio jacks and Dual RCA
jacks that correspond to microphone input, line input, line output, and headphone
outputs.
The EVM includes 4 user LEDs, and 4 position user DIP switch which can be used to
provide the user with interactive feedback. These interfaces are implemented via
2
I C expanders.
VLYNQ, USB II, and ethernet MAC interfaces are integrated peripherals on the
DM6467 processor exploiting its system on a chip architecture.
An included +5V external power supply is used to power the board. On-board switching
voltage regulators provide the +1.2V CPU core voltage and +3.3V for peripherals and
+1.8V for DDR2 memory. The board is held in reset until these supplies are within
operating specifications.
Code Composer communicates with the EVM through an embedded emulator or via
the 14 pin external JTAG connector.
1.3 Basic Operation
The EVM is designed to work with TI's Code Composer Studio development. Code
Composer communicates with the board through the embedded emulator or an
external JTAG emulator. To start, follow the instructions in the Quick Start Guide to
install Code Composer. This process will install all of the necessary development tools,
documentation and drivers.
