MCP3221 12bit ADC I2C

This is a working code

#include <Wire.h>

#define ADDRESS 0x4D // 7 bits address is 0x4D, 8 bits is 0x9B

void setup(){
Wire.begin(); //conects I2C
Serial.begin(115200);
}

void loop(){
byte ad_high;
byte ad_low;
int Result;

Wire.requestFrom(ADDRESS, 2); //requests 2 bytes
while(Wire.available() < 2); //while two bytes to receive

ad_high = Wire.receive();
ad_low = Wire.receive();
Result = (ad_high * 256) + ad_low;

Serial.println(Result);

delay(10);
}
