Have you contacted the Arduino folks?

I found it!  Unfortunately, it's woefully out of date (pages 23 - 27)...

I can't remember if I thought of it independently or read about someone else doing it but I'll take credit for the idea.   smiley-grin

4 MHz seems to be the most common choice.  I use 1 MHz in TinyISP.  Honestly, I don't think it makes any difference as long as it's at least 4 times the SPI bitrate.

Pin 9.  Excellent choice.  That's the same pin I use for TinyISP running on a 328 processor.

Don't thank me yet (well, you can thank for the effort).  I may not be able to resurrect enough of the memory.  What really pisses me off is I can distinctly remember what the grid looks like just not how I found the document or what else was in the document.  Stupid brain.  Why must you mock me!
7627  Using Arduino / Networking, Protocols, and Devices / Re: SPI issues... works on the NANO, not on the MEGA. Pin numbers are right. Ideas? on: May 09, 2012, 03:17:39 am
Code:
#include <digitalWriteFast.h>

You assume digitalWriteFast is bug-free.  I suggest testing that assumption.

It is incredibly tedious keying in the fuse meanings

A few days ago I crossed paths with an Atmel document that very nicely organized all the fuse bits.  Let me know if you're interested and I'll try to hunt it down.

suggestions are welcomed  ... since no one replied

What is there to suggest?  It looks like a well done project.

60 people viewed this topic since yesterday.  Apparently, the horde agrees with me.
7630  Using Arduino / Microcontrollers / Re: Arduino Uno R3 - burn ATTINY 2313 on: May 08, 2012, 09:16:28 pm

Nope.  No analog-to-digital converter.  It does have an analog comparator.
7631  Using Arduino / Programming Questions / Re: ATtint24 Core Library for Arduino on: May 08, 2012, 05:01:48 pm

Will you be running the ATtiny24 processors from the internal oscillator?  At 1 MHz or 8 MHz?

Or, will you be running the processors from an external crystal or external resonator?
7632  Using Arduino / Microcontrollers / Re: Check if atmega is really dead. on: May 08, 2012, 03:07:42 pm

Do you have a crystal or resonator connected to the "bad" processor?

If not, you just need to provide a clock signal on the XTAL1 pin.  I believe Lady Ada has generously publish an ArduinoISP version that does exactly what you need.  Report back if you have trouble finding it.
7633  Using Arduino / Microcontrollers / Re: Check if atmega is really dead. on: May 08, 2012, 01:53:06 pm

Is it possible the "bad" processor is configured to run from a crystal or oscillator resonator?

the values come continuously

Into what?
7635  Using Arduino / Project Guidance / Re: breaking at 115200bps on: May 08, 2012, 01:17:49 pm
Is it not possible to obtain continuous values from an analog pin using analogRead at 115200 bps

analogRead does not have a "bps".  Are you referring to Serial?

without any breaking taking place?

What breaking would that be?

At lower rates like 38400 , the readings are continuous. Is this a core problem?

What problem?
