Tone library working only with Attiny85 and not with Attiny45

[GoogleCodeExporter]

Used the below code on both attiny85 and attiny45, attiny85 gives the correct 
sound as pwm output on speaker pin. But the same code on attiny45 gives just 
"tip..tip..tip" sound on speaker. Tried different notes and its same also tried 
to play small array to see if its a memory issue but still same. I have few 
attiny45 which I want to use for door bell.

Pasting code below,

=========================


 #include "pitches.h"

 #define SPK_PIN 0 // pin 6


int melody[] = {NOTE_E5, NOTE_E5,NOTE_E5,   NOTE_E5, NOTE_E5,NOTE_E5,   
NOTE_E5, NOTE_G5, NOTE_C5, NOTE_D5,  NOTE_E5};
int noteDurations[] = {4, 4, 2,  4,4,2,  4,4,3,8,  1};

void setup() {

}

void loop() {
  playtone();
  delay(3000);
}

void playtone(){
 // iterate over the notes of the melody:
  for (int thisNote = 0; thisNote < 11; thisNote++) {

    // to calculate the note duration, take one second 
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 1000/noteDurations[thisNote];
    tone(SPK_PIN, melody[thisNote],noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(SPK_PIN);
  } 
}

using latest attiny-core arduino-tiny-0100-0018.zip with arduino 1.0.5-r2

Forgot to mention I tried both attiny45 on 1mhz and 8mhz fuses. For attiny85 
its working only with 1mhz fuse and not with 8mhz but for me that speed is ok.

No hardware details.

What version of the product are you using? On what operating system?
I'm using the arduino IDE v1.0.5-r2 on windows 8.1 using 
arduino-tiny-0100-0018.zip

Sorry forgot to put hardware in initial description please reopen the ticket 
just added one comment for hardware. Thanks in advance

"attiny45", "speaker", and "1mhz" is not a description of the the hardware.  As 
long as you refuse to provide the details necessary to reproduce the problem I 
refuse to accept that this is a problem with Tiny Core.

What steps will reproduce the problem?
1. Connect ATTiny45 with the following pinouts.
   1 - 100K to +5v
   2 - free pin
   3 - free pin
   4 - GND
   5 - 68E resistor to Speaker + and Speaker - to GND
   6 - free pin
   7 - free pin
   8 - +5v

2. Attiny45 at 1MHz and flashed the hex file using usbasp and used the code on 
description to flash file.

Please let me know if you need anything else

5/(68+8)*1000 = 66mA.  66mA grossly exceeds the maximum current an AVR pin can 
provide.  Which means your test case is still invalid.

I tried with 220E and 1k values all of these work with attiny85 kinda strange

Do you need any more info? The bug still says invalid status

In reply #10 you state tone works.

oh reply 10 i mentioned they all work on attiny85 from 68E-1k values only 
difference is volume. But on attiny45 none of the values work. Same circuit and 
same sketch on attiny45 1mhz doesnt work. It works on attiny85 1mhz

You very likely damaged the output driver on your t45 processor.  Until you 
confirm your results with a second undamaged t45 processor this report remains 
invalid.

I tried with 3 attiny45 chips and same result with 220E,no output except tik 
tik repeating noise
