[SOLVED] Trying to control an AD5142 potentiometer with an Arduino

#include <SPI.h>
void setup() {
  
  // pin 10 is the slave select for the digital pot
  pinMode( SS, OUTPUT); // set the slaveSelectPin as an output
  digitalWrite(SS, HIGH); // take the SS pin high to de-select the chip
  
  // MISO input needs to be ;ulled up for the AD5142
  pinMode( MISO, INPUT_PULLUP);
  
  SPI.begin();  // initialize SPI
  
  // set SPI speed to 500 kHertz, MSB, NORMAL LOW CLK and FALLING EDGE
  SPI.beginTransaction (SPISettings (500000, MSBFIRST, SPI_MODE1));

  // make sure the control register is correct:
  digitalWrite(SS, LOW);// take the SS pin low to select the chip
  SPI.transfer(0b11010000); // Copy serial register data to control register command 16
  SPI.transfer(0b00000011); // D2= 0 = potentiometer mode, D1=1 = enables EEPROM programing, D0=1 = allow update of wiper position
  digitalWrite(SS, HIGH); // take the SS pin high to de-select the chip

}

void loop() {
  writeOne();
  delay(10);
}

void writeOne(){
  
  digitalWrite(SS, LOW);// take the SS pin low to select the chip
  
  SPI.transfer(0b00010000); // command 1= set pot, pot selected= 0
  SPI.transfer(0b00000001); // pot value= 1
  
  digitalWrite(SS, HIGH); // take the SS pin high to de-select the chip

}

SPI.transfer(0b00010000); // command 1= set pot, pot selected= 0
  SPI.transfer(0b00000001); // pot value= 1
