MAX31855 Chip Help

Using Arduino Project Guidance

I bought max31855 chip and it is configured for J-type thermocouple since I will be using J-type.
Can I still use max31855 break board code from Adafruit? Im using the same code but I get nothing, no readings.

#include <SPI.h>
#include "Adafruit_MAX31855.h"


#define DO   3
#define CS   4
#define CLK  5
Adafruit_MAX31855 thermocouple(CLK, CS, DO);


void setup() {
  Serial.begin(9600);
  
  Serial.println("MAX31855 test");
  // wait for MAX chip to stabilize
  delay(500);
}

void loop() {
  // basic readout test, just print the current temp
   Serial.print("Internal Temp = ");
   Serial.println(thermocouple.readInternal());

   double c = thermocouple.readCelsius();
   if (isnan(c)) {
     Serial.println("Something wrong with thermocouple!");
   } else {
     Serial.print("C = "); 
     Serial.println(c);
   }
   //Serial.print("F = ");
   //Serial.println(thermocouple.readFarenheit());
 
   delay(1000);
}

Using this code. Is this one built for type-K only?
Hope Someone can help me.

Are there any wiring connections available? I only have the max31855 chip, not the one in adafruit.Maybe, my wiring are incorrect which gives me no readings.
