Use DS3502 digital potentiometer with Arduino support package

I am trying to use a Adafruit DS3502 I2C Digital Potentiometer with the Matlab Arduino support package. I already connected the arduino to the computer and the digital pot to the arduino. I have loaded the arduino and the digital pot device via

ard = arduino;

COM = string(ard.Port);

Board = string(ard.Board);

clear ard

a = arduino(COM,Board,'Libraries','I2C');%load Arduino board

addrs = scanI2CBus(a);

%

ds3502 = device(a,'I2CAddress',0x28);

My question is how do I write to the device? The digital pot has a 127 different resistance values.

You can use the writeDigitalPin function to write into the device of the Arduino. The syntax of the function is: writeDigitalPin(a,pin,value)

This writes the specified value to the specified pin on the Arduino hardware in the connection a
