What steps will reproduce the problem?
1.Make with tiny core including Arduino1.0 that referencesPrint.h
2.
3.

What is the expected output? What do you see instead?
Compile files due to cast differences. arduino.tiny's casts do not match the 
arduino1.0's casts. Specifically, may observed failures is:
/home/user/arduino/arduino-1.0/libraries/SoftwareSerial/SoftwareSerial.h:92: 
error: conflicting return type specified for ‘virtual size_t 
SoftwareSerial::write(uint8_t)’
/home/user/arduino/arduino-1.0/hardware/tiny/cores/tiny/Print.h:71: error:

After upgrading to Ubuntu Ocelot (11.10), projects targeted for ATtinys will 
not compile due to an error with the round function in math.h. This probelm is 
when using Arduino IDE v022. 

The round function is duplicated by a macro in wiring.h. Even though this macro 
has been around forever, and for some strange reason still works when targeting 
ATmega chips, it causes the compiler to choke for ATtiny chips. 

Simply commenting out the line (136) in wiring.h:

//#define round(x)     ((x)>=0?(long)((x)+0.5):(long)((x)-0.5))


fixes the problem.

Does this need to be applied?

Add "arduino:avrispmkii" as one of the examples.

"changed it from "attiny85at8.upload.protocol=avrispv2" to 
"attiny85at8.upload.protocol=arduino:avrispmkii" and it started working great"

Update the comments in pins_arduino.c to accurately reflect the code / hardware.

Ensure the core builds with no warnings...

I am not able to use an interrupt based on a timer overflow on Attiny 84.

This code doesn't work:

int counterT=0;
int starterT=0;
byte state=1;
#define LED 0

void setupTimer() {
    float prescaler;

    //during setup, disable all the interrupts based on timer 0
    TIMSK0 &= ~(1<<TOIE0);
    TIMSK0 &= ~((1<<OCIE0A) | (1<<OCIE0B));
    //normal mode: increment counter until overflow
    TCCR0B &= ~(1<<WGM02);
    TCCR0A &= ~((1<<WGM01) | (1<<WGM00));
    //normal mode: no pwm generation
    TCCR0A &= ~((1<<COM0A0) | (1<<COM0A1));
    TCCR0A &= ~((1<<COM0B0) | (1<<COM0B1));
    //sets the prescaler depending on the system clock
    if ((F_CPU == 16000000UL) || (F_CPU == 8000000UL)) {   
        TCCR0B &= ~(1<<CS02);
        TCCR0B |= ((1<<CS01) | (1<<CS00));
        prescaler = 64.0;
    } else if (F_CPU == 1000000UL) { 
    TCCR0B &= ~((1<<CS02) | (1<<CS00));
    TCCR0B |= (1<<CS01);
    prescaler = 8.0;
    }
    starterT = 256 - (int)((float)F_CPU * 0.001 / prescaler);
    TCNT0 = starterT;
    TIMSK0 |= (1<<TOIE0);
}

ISR(TIMER0_OVF_vect) {
    TCNT0 = starterT;
    counterT++;
    if (counterT>999) { 
        state ^=1; 
        counterT=0;
        digitalWrite(LED, state);
    }
}

void setup() {
    pinMode(LED, OUTPUT);
    digitalWrite(LED, state);
    setupTimer();
}

void loop() {
}

Led lights up forever.

I Use Attiny85. like this
http://hlt.media.mit.edu/?p=1695

#include <EEPROM.h>-- Compile is Passed.
But <EEPROM.h>  does NOT Work.

How to use EEPROM with ATtiny?
or Will be Support?

Can someone add the attiny12(l) to the supported hardware, this chip is cheap 
and can be usefull as FET or transistor or LED driver....

What steps will reproduce the problem?
1.Write some arduino code useing '#include <Servo.h>' to use the servo library 
which is available for the arduino uno (and more)
2.Hit compile
3.Watch the error messages pop up


What is the expected output? What do you see instead?
What I get is: 
E:\arduino-0022\libraries\Servo\Servo.cpp: In function 'void __vector_3()':
E:\arduino-0022\libraries\Servo\Servo.cpp:105: error: cannot convert 'volatile

And it is not compiling

What version of the product are you using? On what operating system?
I'm using the arduino IDE v22 on windows 7 ultimate and added the ATtiny85 
cores accordingly to the readme.txt file in the downloaded package


Could you please consider implementing the servo library into the ATtiny85 core.

Thanks in advance

I reloaded and  and unzipped everything again. Tried to use the MIT hi low tech 
Procedure. Using Arduino Duemilanove.

I would really like to get these inexpensive chips to work. It seems like the 
compiler for got how to find the library files. I tried to add abunch of header 
files but that is not needed if I compile and upload to an arduino.

The following works (it uses empty25at8 from ATtiny25 - I'm not sure what that 
is supposed to be).  Burn Bootloader works fine to set the fuse bits to work at 
8MHz.  I would presume similarly copying the  attiny25at1 entry would work to 
produce the attiny24at1 entry.

The Arduino IDE replaces WProgram.h with Arduino.h, breaking everything.

There's an easy fix: add a file "Arduino.h" inside cores/tiny/ with one line in 
it:

    #include <WProgram.h>

Easy fix. There may be more incompatibilities, but this got my basic sketch 
compiling again.

The zip file, arduino-tiny-0022-0008.zip, contains an eeprom.h file with path 
\tools\avr\avr\include\avr\, however in the stock Arduino-0022 software, a file 
by that name already exists and is slightly larger than the one provided in the 
zip file.

What is the correct course of action for this file?

Attached is a diff file between the two, seems to be related to the Mega2560.

The TIMER_TO_USE_FOR_MILLIS option in "core_build_options.h" should allow timer 
0 to be selected for millis.  This does not work correctly for the ATtiny85 
processor.  Details are here...

As part of Arduino 1.0, I'm hoping to make it easier to use the standard 
Arduino core with different processors.  In particular, there's been a lot of 
work done to remove all #ifdef's based on processor names and replace them with 
register names so that they should work on more processors.  We've also added a 
mechanism (a new BOARD.build.pins preference in boards.txt) that allows for 
boards to use a custom version of the pins_arduino.h (the value of the 
preference indicates the sub-directory of the new pins/ directory in which the 
appropriate pins_arduino.h file resides).  I'd like to improve and extend this 
mechanism to allow for ATtiny support with the standard Arduino core and a 
custom pins_arduino.h file.  

I'd love to have your help with this.  In particular, making sure the 
mechanisms are flexible enough for ATtiny support and in creating the right 
pins_arduino.h files, etc.  

Feel free to reply here, on the developers mailing list 
(http://mail.arduino.cc/mailman/listinfo/developers_arduino.cc), or just by 
opening individual issues on the Arduino Google Code project with changes you'd 
like to see.

The Arduino 1.0 code is available on GitHub: 
https://github.com/arduino/Arduino/tree/new-extension and there's a beta 
release:

Windows: http://files.arduino.cc/downloads/arduino-1.0-beta1.zip

BTW, I'm the lead software developer for Arduino.  Apologies for getting in 
touch this way, but I wasn't sure how else to reach you.

Running the following sketch at 8mhz (internal clock) will produce garbage on 
the serial output:

void setup() {
  Serial.begin(9600);
}

void loop() {
  delay(1000);
  Serial.println("hello world!");
}

At a 1mhz clock this code works fine. Is this due to out of spec attiny's? I 
tested with 5 seperate attiny's. Or, am I missing something crucial here?
What can I do to troubleshoot this issue?

What steps will reproduce the problem?
1.able to program a atttiny 2313
2. pin  as output works fine
3. can not find analog input

What is the expected output? What do you see instead?

I have seen on HardwareSerial.cpp that you disable the library to use the debug.

I'm opening this issue to you document how to enabled it back when you have a 
USART capable ATTINY like attiny2313.

When I try to compile a sketch for Attiny85 with an interrupt service routine 
hooked to TIMER1_OVF I get this error from Arduino IDE:
core.a(wiring.c.o): In function 'init':

/home/percorso/alla/cartella/Arduino/arduino-tiny-022/hardware/tiny/cores/tiny/w
iring.c:234: multiple definition of '__vector_4'
sketch_sep27b.cpp.o:sketch_sep27b.cpp:36: first defined here

If I use the TIMER0 I get no compilation errors.

To reproduce the error, just create a new sketch and copy the following code:

void setup() {
}

void loop() {
}

ISR(TIMER1_OVF_vect){
}

If you change TIMER1_OVF_vect with TIMER0_OVF_vect the compilation ends without 
errors.

(I simplified the sketch, I didn't copy all my code: the example above is 
enough to reproduce the error).
What steps will reproduce the problem?

I'm using Arduino 0022 IDE with Tiny cores 0022.

Remove CORE_DIGITAL_FIRST and CORE_DIGITAL_LAST.  Assume the pin numbers are 
sequential starting from zero.

Please... Need very much.
