Pmod AD1 and Arduino Uno Code

Using this code display the result of A/D conversion of channel A0 on the serial monitor.
* Test of the Pmod
* Description: Pmod_AD1
* The result of A / D conversion of channel A0 is displayed on the serial monitor.
* Material
* 1. Arduino Uno
* 2. Pmod AD1 

#define CS 10 // Assignment of the CS pin

#include <SPI.h> // call library

int i;
byte recu[3]; // storage of data of the module
int X;

void setup()
 Serial.begin(9600); // initialization of serial communication
 SPI.begin(); // initialization of SPI port
 SPI.setDataMode(SPI_MODE0); // configuration of SPI communication in mode 0
 SPI.setClockDivider(SPI_CLOCK_DIV16); // configuration of clock at 1MHz
 pinMode(CS, OUTPUT);

void loop()
 digitalWrite(CS, LOW); // activation of CS line
 for (i=0;i<2;i=i+1)
   recu[i] = SPI.transfer(0); // send 2 data to retrieve the converted value on 2 bytes
 digitalWrite(CS, HIGH); // deactivation of CS line
 X = recu[1]; // X is in a 12 bit format
 X |= (recu[0] << 8);
 for (i=0;i<2;i=i+1) // Send in serial monitor
   Serial.print('\t'); // tabulation
