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.
