TAS3308 DSP Functional need help.

Other Parts Discussed in Thread: TAS3308

Hello, Ti!

I want to use TAS3308. But i need equalizer (i need bass boost and other effects)

I think i have to:

1. Compile algorithms  in PurePath Studio

2. Write compiled algorithms into EEPROM

3. Connect EEPROM to TAS3308 using I2C master lines

And after that TAS3308 transmit  code into DSP core.

Please, explain me mechanism how i can do this, if it possible.

With best regards, Vladimir.

    Vladimir,

           PurePath Studio can be used to do this for you if you use an TAS3x EVM with the appropriate USB-to-I2C converter chip (TUSB3210PM). If you don't have a TAS3x EVM, you'll need to take the <.image> binary file and burn it to an EEPROM. 

          Once the EEPROM is attached to the TAS3308, simply perform a power-on-reset (POR), and the TAS3308 ROM code will take care of downloading the code from the EEPROM, and setting up the system for you. If this is sucessful, GPIO1 will be driven low. (Typically ~800ms post POR)

          The only thing you'll need to do post EEPROM download will be to correctly configure the peripherals around the DSP core for desired operation. This is done via writting to the I2C Registers.

    Drew,

    Is it enough to have TAS3308EVM-LC to write external EEPROM, or i have to buy full version TAS3308EVM.

    Sorry, for the question, but i can`t  find documentation for both modules.

    With best regards, Vladimir.

    Either one will work. Both EVMs have the USB-to-I2C chip installed
