Hello i am using AD5270 with MCU(STM32F4). 


i want to control resistor only using RDAC, so i send command 


1) 0x1C02 ( RDAC register write protect - allow update of wiper position through digital interface )

2) 0x0464 ( Send data 100 ) 



i attached oscilloscope file. Please refer followings;


After sending the commands, AD5270 doesn't change resistor value .


please check and send to me for confirmation.


thank you.


Best regards,
