AD5274 digital POT problem

hello friends :slight_smile:
i’m new for this forum and I’m excited to be here

i’m trying to use a digital pot “AD5274”

so i coded like that

#include <Wire.h>

void setup() {
Wire.begin(); // join i2c bus (address optional for master)

void loop()
Wire.beginTransmission(44); // ADDR to Vdd
Wire.write(0b01011000); //serial bus address byte write
Wire.write(0b00000100); //Write command content on RDAC
Wire.write(0b00000001);// Write 1 on RDAC

but there are some problem

( scope captured photo on attached file )

only first data goes to ic

how can i change my code to send all bytes ?


"only first data goes to ic" - what does this mean exactly?

"how can i change my code to send all bytes ?" - what bytes?

your photo is too low a resulution to be useful.

that means like it (sorry for my bad english )

Wire.write(0b01011000); Wire.write(0b00000100); Wire.write(0b00000001);

i write 3 frame on i2c, but only first frame shown by scope

i'll reupload photo soon :)

thank you for your reply
