not a suggestion but maybe a warning.  I have an HP Pavilion dv6000 laptop with nvidia gpu and amd cpu.  These things are apparently infamous for heating up to the point where the gpu fails.  sometimes cured by resoldering the nvidia chip, sometimes(like mine) the whole motherboard needs to be replaced.

I hope your issue is unrelated.

This is pretty amazing.  shows current and voltage flow in a wide variety of example circuits.

I WAS planning to pop the 644 out of my sanguino and drop it on a breadboard because the sanguino is so wide it covers up all the traces and is hard to connect to.

BUT  I just noticed yesterday that the sanguino software only seems to be up to version 12 of the arduino IDE!

meh, it looks like an Iphone for old people

Yeah, I want one but it's a bit goofy looking.  I saw jobs holding it and in my head I could hear him saying "We are on the track of the 50 fit woman.  I have found her iPhone".

Arduinos certainly get used to control CNC-type machines and there are heavy-duty shielded models specially made for the purpose.

I believe there are wireless (wifi and bluetooth) cameras that would connect to your laptop directly.

I tried it on Windows XP. When I move the mouse up to the part window to see what parts are available, I get the blue screen of death.

Makes slow going designing circuits...

yes, that would slow you down all right!

I guess it's more likely a java issue or windows rather than fritzing itself but...

I'm running fritzing on vista but my XP box was whining at me today to upgrade java, maybe that's worth a check.

I believe there's a new release of fritzing coming soon.  maybe we can take that as an event to generate some interest in places like this forum, make magazine, hack-a-day etc.

I personally have used it to document a couple of projects.  The software is conceptually amazing but I haven't quite done anything useful with it.  For one thing I find the parts choice and representation make it hard to make a tidy breadboard or schematic.(look at the breadboard power supply below).  I'm hoping the new release will help and that we'll get more examples I can learn from.

The Tom Igoe book "Making things talk" was an inspiration even if I didn't make those actual projects.



I did get a C language reference book from the library and work through it but I'm still learning a lot as I go along. I learned the most from doing small projects and asking questions here.

I should have re-posted.  as it happens processing was perfect for the specific task I was tackling that day.  I was able to read in a .wav file, go over the sample data making changes and rewrite the file.  Munging in code from oscilliscope application let me see the effects as i was working.

I have processing and i use it for graphics but I didn't think it could do much in the way of file i/o.
987  Forum 2005-2010 (read only) / Bar Sport / C language IDE for windows file manipulation? on: October 15, 2009, 08:00:35 pm
I currently use a painfully old copy of dos quickbasic for doing quick and dirty file manipulation tasks on my pc (read a .wav file and do something or other with the data).  It works but it's not happy with vista directory structures, it has dos rather than windows keyboard shortcuts, and it would be good to have the same language on the pc as the arduino.

I'd like to find something fairly lightweight for my swiss-army-knife needs.  What do other people use?

My board = Uno
Devices I want to use (and load bootloaders on)  = Atmega 48v running at 10mhz, 88, 168 and 328.
those are all in the list.  Note that the 48 won't support a bootloader.

Method = breadboard with crystal connected to Uno board.
I have fumbled around with using arduinos as programmers with variable success.  I eventually bought a programmer.

Once the bootloader is on are you going to plug these into the arduino to load a sketch then plug them into some other circuit to run in?

I'm a little leery of the 10mhz crystal, some of the arduino stuff is fine with oddball speeds, some of it insists on either 8mhz or 16mhz.  Also, if these are factory fresh chips they're likely set up to run on the internal oscillator so you could skip the crystal on your breadboard.

As you note, I'm geographically close (Orleans) and I don't mind helping physically.  You could mail me chips for programming or maybe a phonecall would help.  PM me if you want to follow up.

I have support for a LOT of different vesions of the ATMEGA chip in my version of the libraries. Refer to

http://www.avr-developers.com/

That's a great resource - thank you very much.  I found this in pins_attiny45.c - I guess this would hold for the '85 - right?

Code:


// ATMEL ATTINY45 / ARDUINO
//
//                  +-\/-+
// Ain0 (D 5) PB5  1|    |8  Vcc
// Ain3 (D 3) PB3  2|    |7  PB2 (D 2)  Ain1
// Ain2 (D 4) PB4  3|    |6  PB1 (D 1) pwm1
//            GND  4|    |5  PB0 (D 0) pwm0
//                  +----+


So I take it that we have 4 analog input pins, 6 digital I/O, 2 analog out (overlapping obviously).

How do you handle the timers and other internal differences?  Should most libraries work?  What about specifically software serial and servos?

Ok, here's the todbot item on standalone arduinos with atmega8's.http://todbot.com/blog/2009/05/26/minimal-arduino-with-atmega8/ it covers the bootloader and crystal vs internal issue and may give you some help.

atmega88's are pin compatible with atmega8's but have some internal differences. per this http://www.atmel.com/dyn/resources/prod_documents/doc2553.pdf
