646  Using Arduino / Microcontrollers / Re: Comprehensive ATtiny libraries overview? on: January 15, 2013, 11:07:15 am
I have just tried the new Manchester library mentioned here:

http://mchr3k-arduino.blogspot.dk/2012/02/wireless-sensor-node-part-6.html

It runs flawless on a Attiny85 as TX.

The transmitter is the same as  robitabu use

The receiver:

Is that your site? It is very clear!

Thankyou  GoForSmoke, yes it is my site

I guess the micro is the same as the Leonardo, so maybe takke a look at this:

With an Arduino Uno the steps are:

Regarding the DS18B20 and OneWire, I have succesfully used the example code found here on a Attiny85

Or you could use one of these cheap USB/Serial converters:

I see, sorry about that.

No, i have never tried to remove the chip, I just connect reset to ground and do a manual reset on the target.

I know the safe way is to upload a empty sketch and use resistors on the tx,rx lines but I must admit that I seldom do that.

The connection for uploading is just the following:
D0 to D0
D1 to D1

Try swapping these, it should be tx->rx and vica verca

Det er skam ikke kun et MAC problem.
Jeg får samme meddelelse en gang imellem på en Windows maskine. Jeg gør simpelt hen det at jeg frakobler min arduino's USB stik, venter nogle sekunder, og tilkobler igen.

but I actually wanted to establish a pin change interrupt

If you want a pin change interrupt, you should look in table 9.3.2 and 9.3.4

You can choose whatever pin you want, below I have chosen pin PB3

Code:
ISR(PCINT0_vect){
digitalWrite(PB4,!(digitalRead(PB4)));
}

void setup(){
pinMode(PB4,OUTPUT);
GIMSK=_BV(PCIE);  //Table 9.3.2
PCMSK=_BV(PCINT3); //Table 9.3.4
}

void loop() {}

I do not know whether that works with the Attiny45
It does, actually it is not a library, it is part of the tiny core.

it is meant for me to understand the basis of timers.

I see, in that case I will follow your progress, I have never fully understood them either.
I once was adviced by Coding Badly to use Timer0 instead of Timer1 because it is much different than timers on other Atmels

Is there a reason for not using the tone() library to achieve what you want

I was thinking something like 5000mAh 50C 7.4V  would do.

If that is a 2 cell  LiPo pack (which I asume from the 7,4V rating) you should rember that when fully charged the voltage will be 8,4V, which is too much for your servos. You will need something like this:

That one is only rated a 3A, which may not be enough, depending on how many servos are used at the same time, and how much load you put on them.

If I understand your question:

The tiny's 45/85/2313/84 are included in the tiny core:

In RC-model air planes we often use these ferrit rings on the servo leads, close to the receiver to avoid noise problems.

I just got a pair of these in the mail today.
I tried to use  Serial.print and the txrx ports of Arduino, but that was not a success.

Then I tried VirtualWire, and now I have over 5m range through a concrete wall.
So for my project, a simple outdoor temp. sensor I am pretty sattisfied.
