After completing the software installation, turn on power supplies and connect the USB cable to the Input-USB board. To start the GDE, go to the Start menu and select All Programs/Texas Instruments/PurePath Studio/Pure Path Studio GDE. Figure 2-1. GDE Startup The start-up of GDE takes a few seconds. -

At this point, a process flow can be built using the TAS3208 application framework, the TAS3208 I/O components, and the audio processing components. Building and running a process flow A good starting point is to load the predefined TAS3208 Test process flow. -

The TAS3208 then loads the EEPROM image and the TAS3208_init_master/slave.cfg file. At this point, the TAS3208EVM transitions to the run mode with the mute in the ON state. For the TAS3208 to stream audio out of the DAC outputs, the mute must be returned to the inactive state. - Page 22 Quick Setup Guide SLEU092 – February 2008 Submit Documentation Feedback...

Page 30: Example Of Msp430 Programming
www.ti.com Example of MSP430 Programming Example of MSP430 Programming The MSP430 can be programmed to provide TAS3308 and power-stage initialization and control. During initialization, the MSP430 should wait for the TAS3308 to complete booting from EEPROM. It then sends an initialization sequence to the TAS3308. At this point, the MSP430 sends I C commands to the TAS3308 when it receives an input from one of the onboard switches or the IR remote control. -
