Manchester Library Won't Compile for Attiny85 I am creating a wireless sensor using an Attiny85.  I want to send the data to an arduino uno, so I purchased the 315mhz rf link kit from spark fun.  Since the Attiny85 does not have a TX I decided to use the Manchester library however it won't compile on the Attiny85.

I followed the steps from this blog :

Here is the code I am using:

    #include &lt;WProgram.h&gt; //otherwise it says it can't find Arduino.h
    #include &lt;Manchester.h&gt; //include the library to comunicate
    #define TxPin 2 //the pin that is used to send data

 int sensorPin = 4;
 int ledPin = 3;
 int count = 50;

 void setup(){
  pinMode (ledPin, OUTPUT);
  man.workAround1MhzTinyCore(); //add this in order for transmitter to work with 1Mhz Attiny85/84
  man.setupTransmit(TxPin, MAN_1200); //set transimt pin
}

void loop(){
  if (count == 50){
   digitalWrite (ledPin, HIGH);
   count = 0;
   }
   int data = analogRead(sensorPin);
   man.transmit(data); //transmits and reads the data
   delay (100);
   count ++;
 }


Here is the error message:

attiny is missing an option required to allow the Manchester library to function properly on ATtinyX5 devices, specifically definition of __AVR_ATtinyX5__ when a device is selected. In fact, it's missing quite a few things. 

The package I use for ATtinyX5 support is arduino-tiny. I have verified that it defines that symbol properly. I recommend that you dump your current support package and install arduino-tiny instead.
