Attiny 85 RF

Using Arduino Project Guidance
5

Well I tried this manchested library, but I always get this error when I try to upload the code in attiny85 :

#include "MANCHESTER.h"

#define TxPin 1  //the digital pin to use to transmit data

unsigned int Tdata = 32;  //the 16 bits to send

void setup() 
{                
MANCHESTER.SetTxPin(TxPin);      // sets the digital pin as output default 4
}//end of setup

void loop() 
{
 //Tdata +=1;
 MANCHESTER.Transmit(Tdata);
 delay(100);
}//end of loop
