Hi Guys, I have been trying to interface CC2500 with my G2 launchpad, i am unable to do so. 

i interfaced cc2500 with the default spi configuration given in the SPI library with Energia.
P2.0 - CS (active low)
 P1.5 - SCLK
 P1.6 - MISO aka SOMI
 P1.7 - MOSI aka SIMO
P19- GD0
GDO2 pin is hanging
i found a library which i used to code, the code initially checks the value in the registers of cc2500 and serially prints it and matches it with the default values.
i have attached the thumbnails of serial output. when my CS pin is connected i get "o" output for all reisters and when i leave it open i get "FFFFFF"
what can i do to correct that.. 
here is the code i used:
#include <cc2500_REG.h>
#include <cc2500_VAL.h>


#include <SPI.h>

#define CC2500_IDLE    0x36      // Exit RX / TX, turn
#define CC2500_TX      0x35      // Enable TX. If in RX state, only enable TX if CCA passes
#define CC2500_RX      0x34      // Enable RX. Perform calibration if enabled
#define CC2500_FTX     0x3B      // Flush the TX FIFO buffer. Only issue SFTX in IDLE or TXFIFO_UNDERFLOW states
#define CC2500_FRX     0x3A      // Flush the RX FIFO buffer. Only issue SFRX in IDLE or RXFIFO_OVERFLOW states
#define CC2500_TXFIFO  0x3F
#define CC2500_RXFIFO  0x3F

#define No_of_Bytes    3

const int buttonPin = 5;     // the number of the pushbutton pin
int buttonState = 0;         // variable for reading the pushbutton status

const int GDO0_PIN = 19;     // the number of the GDO0_PIN pin
int GDO0_State = 0;         // variable for reading the pushbutton status
int led = 2;
void setup()
{
  Serial.begin(9600);
  pinMode(SS,OUTPUT);
  pinMode(led, OUTPUT);
  digitalWrite(led, HIGH);
  SPI.begin();
  digitalWrite(SS,HIGH);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);     
  pinMode(GDO0_PIN, INPUT);     

  Serial.println("Starting..");
  init_CC2500();
  Read_Config_Regs();
}

void loop()
{
Serial.println("Starting..");
  //Read_Config_Regs();
  /*
//  To start transmission
    buttonState = digitalRead(buttonPin);
    Serial.println(buttonState);

    while (!buttonState)
    {
        // read the state of the pushbutton value:
        buttonState = digitalRead(buttonPin);
        Serial.println("PB = 0");
    }
    
    Serial.println("BP = 1");
    */

    }
