I have the MAX31855x8 board
It uses a binary code to output.
This is what I have as of right now. I got the data to come out through the counter and if statements but now if I try to see just T0 at any given time it gives me a random temperature. It may be any from T0 to T7. I do not know why it is doing this.

//Thermocouple setup
//Pin connections to the MAX31855x8 board
//The power requirement for the board is less than 2mA. Most microcontrollers can source or sink a lot more
//than that one each I/O pin. For example, the ATmega328 supports up to 20mA. For convenience, the board
//is placed directly on top of a row of I/O pins on the microcontroller. Power is supplied to the board by
//holding the GND pin low and the VIN pin high
#define GND 2
#define T0 3
#define T1 4
#define T2 5
#define VIN 6
#define MISO 7
#define CS 8
#define SCK 9
// Create the temperature object, defining the pins used for communication
