1. No address is fixed and cannot be changed.

2. Programs are linear in the EEPROM, i.e. program 0 starts are address 0 and continues for 512 bytes (0 - 511), program 1 starts at 512, etc.

You can make any changes as required for your use but be aware that the DAC is a sigma-delta so it will require some low pass filtering to remove the out of band noise.

Check the voltage levels at the S pins to see if they are getting the proper level, if they are not then back track from the pin to see where the issue is. I would guess that S1 is not seeing the prop ...

Indicates an issue with the soldering of the FV-1, reflow the pins and make sure to clean any flux residue from the board.

All I can suggest then is you check your board and make sure the POTs are working properly.

Finaly it seems capable of synchronised ganging of several dsps, and daisy chaining digital audio buses in between them.

Yes, that is the intent of the 2 I2S buses and the master/slave option.

Good questions. If you have 4 layers and good ground then there is little to gain from split Vdd.

As to LP filtering the AVDD line if splitting Vdd I have found that to help only when using a swit ...

Actually it is a bit more complex than that, you really should not connect to it.

True, I really like DipTrace and we use it in house but the autorouter is only OK. I tend to hand route my boards as I can see better routes than the autorouter or better changes to open up a path. If ...
