    Hello,
    
 
    Can I drive evaluation board AD7294-2 with Arduino Uno? I tried to establish connection on I2C bus without success.
    
 
    Thank you in advance,
    
 
    Svetlana

      Hi,
      
 
      It looks like you are doing a read from  a write-only register (as per Table 9, address 0x00 is for the command register and it is write only). Can you do a read of another register with read or read/write access and see if you get an acknowledge bit?
      
 
      Also, can you double check if the evaluation board actually has pullup resistor? If you can, kindly send me a snapshot of your board.
      
 
      Regards,
