Hi


I am using ADAU1761 and i have connected both ADDR1 and ADDR0 to GND.

According to the datasheet (Table 21), the ADAU1761 12c address for writing to a register might be 0x70. and for reading might be 0x71.

 

Am I right?

 

My DSP is responsing when I used 0x38 for writing to a register, but I get Nack for 0x70.

I try to use 0x39, 0x71 as address for reading a register, but I got Nack.

 

Can somebody please help me this? I have used a lot of time for solving this problem.

 

Thank you in advance
