    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

        Hello Svetlana,
        
 
        yes, it is possible. Arduino Uno has a standard I2C interface and runs at +5V.
        
 
        Is your Vdrive voltage set to +5V?
        
 
        What is your AVdd voltage?
        
 
        Did you mount appropriate pull-up resistors on SCL and SDA? - I guess there are no pull-ups on the Ard. uno board.
        
 
        Is there any toggling on the bus pins? - Could you check it with your oscilloscope?
        
 
        Good luck,
        
 
        Reinhard
