I'm trying to program my ATtiny 13 - 20PU. An it seems to work, but there is no action upon the "delay" command. If on the sketch below I comment out the "High" line, my led is off all the time and whenever I have a Pin 4 High, it's on all the time! Basically this seems to be a frequency/fuse/bootloader problem and made me think the upload was broken.

I added a led between the tiny's pin 3 (digital pin 4) and ground with a 1k current limiting resistor. This one is for testing with the attached sketch. I also tried this breadboard circuit, which gives exactly the same results.

Upon upload to the tiny I get this:

Sketch uses 380 bytes (37%) of program storage space. Maximum is 1,024 bytes.
Global variables use 8 bytes of dynamic memory.

(Everybody warns about 2 errors occuring upon a proper upload - I don't get those).

And I choose the settings: Board ATtiny, Processor ATtiny13, Clock 9.6 MHz (internal), Port Arduino Uno (same as when I upload the ISP sketch), Programmer Arduino as ISP. I upload by clicking "Upload using Programmer".

Arduino Software is 1.6.4, the programmer Arduino is an Uno SMD edition. I used this programmer and this tutorial for smeezkitty core13.

I'm trying to upload this sketch:

// Blink sketch to test ATtiny Chips
// ATMEL ATTINY13 / ARDUINO
//
// +-\/-+
// ADC0 (D 5) PB5 1|* |8 Vcc
// ADC3 (D 3) PB3 2| |7 PB2 (D 2) ADC1
// ADC2 (D 4) PB4 3| |6 PB1 (D 1) PWM1
// GND 4| |5 PB0 (D 0) PWM0
// +----+
const int LED_PIN = 4; // digital pin
const int DELAY_TIME = 1000; // time between blinks [ms]
void setup() {
 pinMode(LED_PIN, OUTPUT);
}
void loop() {
 digitalWrite(LED_PIN, LOW);
 delay(DELAY_TIME);
 digitalWrite(LED_PIN, HIGH);
 delay(DELAY_TIME);
}

Trying to burn a bootloader with the same settings as uploading to the tiny and then tools -> burn bootloader, get's me the error: 

"efuse" memory type not defined for part "ATtiny13"
Error while burning bootloader.

Skimming through the data sheet I noticed that the tiny13 - 20PU (the 20) stand for 20 MHz,... theoretically one should be able to downclock them to the ordinary 10 MHz, but maybe this is my problem?

  • Most likely a mistake in the construction of your ISP stripboard shield. I'd check for dry joints, uncut cuts, etc. Commented May 9, 2015 at 10:54
  • I checked the connections many times now. And since nothing happens, when I try to upload using a breadboard-version, I guess there is some software issue, or I do something wrong. Commented May 9, 2015 at 20:46
  • The last time I programmed an ATtiny (an 85 in my case) using the ArduinoISP sketch, I had to set the IDE to use the right programmer: Tools -> Board -> ATtiny85 (w/ Arduino as ISP) and Tools -> Programmer -> Arduino as ISP - the messages you are seeing suggest the IDE is targetting an STK500 programmer. This may be right as several programmers emulate an STK500 - but it might be worth checking/experimenting with this. Commented May 9, 2015 at 22:22
  • Yeah, as mentioned above, I've used ATtiny13 and Programmer Arduino as ISP. I have no clue, what is going wrong there. Or even how I can debug it further. Commented May 10, 2015 at 8:12
  • Arduino_ISP emulates the avrisp tool. You may try to add something like attiny.upload.protocol = avrisp to your boards.txt. Commented May 10, 2015 at 15:51

There was some mistakes in the boards.txt it seems. After finding a very detailed and extensive boards file here, I modified it to have neat and tidy categories and is easier to use to become a working boards.txt. I had to burn the bootloader once to set the fuses right. After that everything works like a charm for 3 ATtiny13! No warnings or errors. This is used with Arduino 1.6.4. The folder tree is ~Arduino/hardware/attiny/avr/cores/core13 and ~Arduino/hardware/attiny/avr/boards.txt

The "efuse error" on burning the bootloader is described in the article you refer to and a solution is given there as well. It occurs when the attiny13 is defined in the same group as the attiny25/45/85 as the former has no efuse and the latter do.

Giving the attiny13 its own menu entry in the IDE -as described in that article- should solve that.
