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,

Tak Young
