Maybe this will help

Using Tiny Tuner v2 on a ATTiny13 @1.2MHz

I deleted most of the debugging text which gives a sketch size: 986 bytes
The tuned frequence was 1.194 MHz !

I even have an EEPROM address range in mind for configuration data.  If you're interested just let me know.
I am interested

Besides the other improvements of TinyTuner you mention, I think the biggest advantage is that it can be used with TinyDebugKnockBang.
No more fidling with Serial/USB converter and wiring.

Once again Thankyou for maintaining and improving the Tiny core

So, TinyDebugKnockBang remains a library.

That's good news, thankyou.

I did an experiment with a Attin85 @ 8MHz and TinyTuner2

First I tuned it with the "old" TinyTuner, and then with TinyTuner2

Both gave the same OSCALL values, and the tuned frequence was approx. 8,02 MHz

Next I will try Attiny13, it is a tight fit, but deleting some of the debug text should do it.

I like the flexibilty of a library.
I have used it with other cores for example attiny13 and Atmega8 and Atmega328.

what's TinyISP?

It is a replacement for ArduinoISP.
One of the great features is that it use the MISO line to communicate, so you don't have to use a Serial/USB converter every time you want to have debugging output

http://forum.arduino.cc/index.php?topic=123388.30

There are several options, but the TinyTuner2 example use TinyKnockBang, see  reply #37

Here is an overview

With the above mentioned correction to TinyKnockBang.h

I got TinyTuner2 running.

Running t861 @1MHz I got this result :

Code:
// Initial value of OSCCAL is 0x9F;

  // Add the following line of code to the top of setup...
  OSCCAL = 0x

Edit:
After remembering to connect the tune pin to XTAL2, I get:

Code:

  // Initial value of OSCCAL is 0x9F;


  // Add the following line of code to the top of setup...
  OSCCAL = 0x9B;

I think you have to ammend the t861 In TinyKnockBang.h

line 42

Code:
#if defined( __AVR_ATtiny13__ ) || defined( __AVR_ATtiny25__ ) || defined( __AVR_ATtiny45__ ) || defined( __AVR_ATtiny85__ )|| defined( __AVR_ATtiny861__ )

I am using TinyISP with no problem to read fuses and program the chip.

My attiny861A came with theese fuses:

lfuse: 62
hfuse: DF
efuse: 1

I have bought it on E.Bay but I) assume that this is the factory default setting.
Ok I can see it is the same as Hiduino

Or upload the HEX to your new UNO

Has anyone successfully used this library before?

Oh yes

but nothing has changed

What exacly are you trying to do ?
357  Using Arduino / Motors, Mechanics, and Power / Re: Brushless motor control with Arduino UNO on: June 19, 2013, 03:39:28 am
A rc ESC expects a signal just like a rc servo, so you should use the servo library.

Connect the black wire from the ESC to ground on your Arduino and the white or yellow wire to the pin on your Arduino that you chose.

Don't connect the red wire to the Arduino, it is 5 Volt that is used to poer a rc receiver

I think they work in much the same way here in Denmark.
They probably think that small parcels and letters are not worth much, while packages are more suspicious.

The two times I have paid customs and VAT, it was relatively large and heavy packages.
And then they demanded to see the invoice/Paypal receipt

I think they also take samples too, but I do not know
359  International / Scandinavia / Re: Shipping/Customs to Denmark / Scandinavia on: June 18, 2013, 02:43:53 pm
Hi Terry,

The danish rules for custom and VAT are:

If you buy for less than 80 DKK (14 USD) it is free of VAT and Custom fee
If you by for less than 1150 DKK (205 USD) it is free of custom fee, but you pay VAT which is 25%
If you buy for more you pay both VAT and custom fee

On top of this the Danish Post Office are billing you 160 DKK (29 USD) for doing the paperwork.

So an advice is: buy small pckets, worth less than 14 USD

As you probably know, they are always marked as "gift" with some bogus value.

I don't think Danish Customs pay much attention to that smiley-grin

the delay(15) is in the two for loops.

so a total of 360x15 ms
