I tried to change the RDAC Register value of AD5274BRMZ-20 (20K-Max) through I2C. But the resistance between the A & W pins is always constant to 9.25K(Mid Value).
I have sent the following Values through I2C.
Device Address : 0X2C (I have tried 2F also)
Command bits : 0001 (C3,C2,C1,C0)
Attached the Image of the Waveforms. Could anyone let me know, where it went wrong.
