Hello,
We are using the development board for the ADAU1452 because we need to implement a big delay (we expect to be able to delay our sound up to 35 seconds). I am trying to use the functionality but I cannot make it work.
My setup is:
- I have soldered a SOIC8 memory (W25Q32JVSSI) to a breakout board and, with ~2-3 cm cables it has its VCC, GND, DI, DO, CLK pins directly to the TP of th evaluation board.
- I have placed 10Kohm pull-up resistances between nWP and nHOLD pins to VCC
- I have soldered the CS pin to MP9 (TP29), and placed a 10Kohm pull-up resistor to VCC
- I have checked that the first byte sent on the bus was 0x06 (as this topic suggested that was happening in an old version of SigmaStudio)
- I guess that the other topic that Alex@@@123 is also resolved and working smoothly at the SigmaStudio UI
- I even tried to use Chip ID 0 (so use the onboard memory) but I had no different results, I hadn't any audio at the output. I have not changed the onboard memory with my own memory, though. I was expecting to be able to use an external chip as I a m planning to add two of them and test my program for delaying two audio channels by those big delay times.
I kindly ask AD support people (especially DaveThib as he seems to know this topic quite well) so I can use this chip for implementing big delays.
Many thanks in advance. Best regards,
Manuel
