31  Using Arduino / Microcontrollers / Re: Arduino bootloader on atmega8 default fuse settings?? on: March 04, 2011, 09:45:24 am
This is not really a answer to your question........but....

Do you have an Arduino board? If so....you can use that as a programmer.

And we can show you how to do it easily.

BUMP  smiley-confuse

I don't like to bump stuff......but I would also really like to have this!

a atmega8 optiboot compiled for 8MHz

Glad it works! Have fun now!
34  Using Arduino / Microcontrollers / Re: Burning Bootloader on 328p using Arduino Diecimila w/168 on: March 03, 2011, 01:53:20 pm
This is what I did with my Uno and it worked.

Gave the same instructions to 2 other members and it worked for them also.

Ok let's just start over.

First you need a board with a working atmega.
Then there are 2 steps. 1- Put the boot loader on the chip (this might be done already) 2. Put the sketch on the chip.

To do the first part, load the Use Arduino as ISP sketch to the chip on the board.
Make sure you ave selected the right board and the right port.
Then connect you breadboard like this (bottom secion of this page) Circuit (targeting an AVR on a breadboard) http://arduino.cc/en/Tutorial/ArduinoISP
Like I said it only worked if I used an external clock. (I have the Uno board, with optiboot)

Then use the burn bootloader with arduino as ISP.

Now your new chip as a bootloader!

Then remove the chip from your board.

You could just pop the new chip on the board and program any sketch you would like on it.

But is you want leave the chip on the breadboard and load  a sketch on in.........do this.....

Disconnect wires to header pin 10,11,12,13 and connect pins rx and tx the the rx and tx pins on the atmega on the breadboard. Like this
http://arduino.cc/en/Tutorial/ArduinoToBreadboard  Uploading Using an Arduino Board

Then add a wire from the board socket pin 1 (reset) to the breadboard chip pin 1 (reset)

Then load the sketch you want to the chip on the breadboard.


Remember never to change the board selection............but like I said it only worked with an external clock.

Do all of this with your Uno board.

Hopefully they dont have older bootloader otherwise I want a refund from Sparkfun smiley

I get mine from Futurlec 3.50$ and I put the optiboot on them myself using the Arduino as ISP.
37  Using Arduino / Microcontrollers / Re: Unable to upload to AtMega328 on breadboard on: March 03, 2011, 10:01:11 am
Wooooo hoooooooo!!!!

That's the exact same thing I said when I finally got it to work.
38  Using Arduino / Microcontrollers / Re: Unable to upload to AtMega328 on breadboard on: March 03, 2011, 09:50:09 am
The problem with the "Uploading Using an Arduino Board" example, is that they don't tell you that you need a wire connecting the 2 reset pins.
39  Using Arduino / Microcontrollers / Re: Unable to upload to AtMega328 on breadboard on: March 03, 2011, 09:24:25 am
I built something for that a while ago, but doesn't require taking the chip out of the arduino:

http://arduino.cc/forum/index.php/topic,8084.0.html

That's a great idea....so simple. Why didn't I think of that?

Not in the US but they ship to the US

Futurlec www.futurlec.com
Tayda www.taydaelectronics.com/servlet/StoreFront

Very good prices, no minimum purchase, shipping charge are very good, just a bit slow on shipping.
41  Using Arduino / Programming Questions / Re: Need help changing the Arduino as ISP sketch on: March 01, 2011, 07:55:18 pm
It's not working?  smiley-confuse

I get these errors:
avrdude: stk500_program_enable(): protocol error, expect=0x14, resp=0x50
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51



All I did was change the #define RESET SS to #define RESET 2
42  Using Arduino / Programming Questions / Need help changing the Arduino as ISP sketch on: March 01, 2011, 04:57:05 pm
How can I change the Arduino as ISP sketch so it uses pin2 instead of pin10 as the slave reset?

Sounds simple.........but I can't figure it out? smiley-red
43  Using Arduino / Microcontrollers / Re: Re-burning bootloaders on: March 01, 2011, 11:30:18 am
I will test tonight If I can load sketches to the chip on the breadboard without removing the chip on the board and changing wiring. If I disable the auto-reset.
44  Using Arduino / LEDs and Multiplexing / Need help replicating the Nerdkit LED array project on: March 01, 2011, 11:25:41 am
I would like to build this nerdkit project http://www.nerdkits.com/videos/ledarray2/

I have no problem building the LED array.

But converting the code to Arduino is way out of my reach for now.  smiley-red

Any body willing to help me on this?
45  Using Arduino / Microcontrollers / Re: Re-burning bootloaders on: March 01, 2011, 07:09:09 am
Did you need to disable the auto-reset?
