you may be able to adapt

to do what you need. This arduino sketch recognises the kind of board it is connected to it (a second board to have its bootloader updated) and uploads the bootloader to the second board.

Once the sketch is one the first board, it can program the second board independently.

thanks - will try it when I'm in the lab.
3  Using Arduino / Installation & Troubleshooting / multiple boards in lab enviroment - found new hardware back on: April 24, 2012, 07:47:51 am
We followed the instructions here to enable different uno and mega boards to be used on different machines in class without found new hardware coming up each time a different board got plugged into a different computer.

Have put off getting any rev3 boards as long as possible as I suspected the change of chip would mean doing it all again - it looks like it does - found new hardware is back.

Is there a shorter route to doing it to 20 machines than the one described here ?

Is there any kind of installer that can be made to do this automatically - for a thing aimed at beginners hand editing the registry to use it in a classroom easily seems counterintuitive

The cookbook second edition is available in early release pdf now, it is about to go to print.

The appendix covering whats new in Arduino 1.0 can be read here

I think firmata does something like what you are asking for - you can control and configure the board from a host computer. There are various implementations for using it over ethernet around, but I think they are all fairly old, so may not work with the most current version.

Would expect to get more info tomorrow

Which section was it under - I had a quick look beofre I posted but couldnt see anything - there are so many sections now, wasn't sure which one someone might have posted it, and they all had new threads in

10  Using Arduino / Installation & Troubleshooting / Details of changes for Uno R2 on: May 17, 2011, 02:01:24 am
Are there details anywhere of the changes to the board for R2?
11  Using Arduino / Project Guidance / Re: A Must Have: Arduino Cookbook on: April 07, 2011, 12:57:15 am
The code is available for download from the books oreilly page.

On the left hand side, just below the cover image.

Paper copies of the book should be in europe next week.

12  Using Arduino / Installation & Troubleshooting / Re: How to know if an UNO is from the very first releases ? on: March 13, 2011, 04:30:33 am
Depends what the issue is.

There is a bug in the firmware of the 8u2, that mostly shows up when using Linux. This is the issue that reprogramming using DFU should fix. Details of how to check the version your 8u2 is at are here.,53638.msg384647.html#msg384647

All boards that have shipped so far are running the original firmaware on this chip.

The other issue with early unos was problems with the version of optiboot (the code that handles uplaoding sketches to the chip) that was on the board. Details and fix here,28074.0.html

13  Using Arduino / Installation & Troubleshooting / Re: checking 8u2 code version on: February 28, 2011, 03:06:19 am
Thanks for the answers. I was thinking that the updated 8u2 code was on shipping boards, so wanted to check whether that was the cause of the issues we were having, but have since seen it is included with ver 22 of the software, but not on shipping boards (or am I mistaken in that).
14  Using Arduino / Installation & Troubleshooting / Re: Arduino Environment won't install / run on: February 28, 2011, 02:49:42 am
Windows 7 does take a ridiculously long time to unzip Arduino. 7zip is free and much, much quicker. You can download 7zip over a slow internet connection install it and use it to unzip Arduino faster than Windows will unzip it.

I have seen errors from the process failing on machines that are taking so long, so maybe try using 7zip and see if that solves your problem.

15  Using Arduino / Installation & Troubleshooting / checking 8u2 code version on: February 26, 2011, 03:52:06 pm
Is there a way to check what version of code the 8u2 chip on a board is running ?
