Other Parts Discussed in Thread: PCM4222EVM
Hello,
We bought 4 of the TAS3251EVM modules to evaluate these chips for use in our active speakers. Our plan is to setup a pair of 3 way active speakers using 1 module in BTL for the mids/tweeters, and 1 in PBTL mode for the woofer per speaker. For the woofer amps in PBTL mode, I will slave them to the mid/tweeter amps via I2S. I also bought a PCM4222EVM ADC board to add analog inputs. Since this board has dual SPDIF outputs, our plan is to use 1 SPDIF out for the right speaker, and 1 for the left.
So far 1 thing I've noticed is the custom config settings all get wiped out as soon as you power down the boards. The boards have 3 presets to choose from, but I don't have any clue how to store configurations into the ROM of the MPS430, so my saved configurations don't need to be loaded from the PPC software to each module every time we power the units down.
What we would like to do is set this system up so all we will need to do is power up all the boards, and our configurations will automatically load at power up. We plan on putting these all in a case, and would like the custom configuration to all automatically load on all 4 boards when I power up. No other configuration required. Simple setup, hit the power button on the front of the case, and start playing music via the analog inputs of the PCM4222EVM.
What would it take for us to set this system up this way?
