Hey, I was trying to programme Attiny85 with mine arduino v3.0, and  when i try to test code or upload it to attiny85 i always get error ""serial" was not declared in the scope". Maybe there is some way to fix this or other way to upload this code into attiny85? Please help. Here is code:

Code: [Select]
#include <IRremote.h>

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup()
{ pinMode(12, OUTPUT);
 pinMode(13, OUTPUT);
 Serial.begin(9600);
 irrecv.enableIRIn();
}

void loop()
{
 if (irrecv.decode(&results)) {                                                                                                                              
   if (results.value==0x086){digitalWrite(12, HIGH); delay(1000);}  
   if (results.value==0x481){digitalWrite(13, HIGH); delay(1000);}  
   if (results.value==0x886){digitalWrite(12, LOW); delay(1000);}  
   if (results.value==0xC81){digitalWrite(13, LOW); delay(1000);}  
   irrecv.resume();                                                                                
 }
}

and error is looks like this :

'Serial' was not declared in the scope

Code: [Select]
IRrecvDemo_Bulb.ino: In function 'void setup()':
IRrecvDemo_Bulb:12: error: 'Serial' was not declared in this scope

The ATtiny85 does't have a hardware serial port so the 'core' doesn't include the Serial object.  Since you don't seem to be using the Serial object, just remove "Serial.begin(9600);" from your setup().

I did this, and now i get this "error compiling"

The IRremote remote library uses timer 2.  The ATtiny85 processor does not have a timer 2.  I have no idea if there is an alternative library.

Than maybe there is other kind of microcontroller that would support these libraries and i could upload programm to it with arduino? :)
