Hi Chuck, We've been very happy with good old CVS. All of our AVR development projects, among many others, are under CVS control. We do frequent backups of the repository, and the repo is composed of a simple directory structure of flat files so it is easy to do a complete backup

I was excited about Box.net until I saw that you can only sync folders if you pay for Business or higher plans.Also, I could not see how one can get 50GB for free. The Folder Sync is important to me; it's what allows me to use multiple PCs with the same data, without having to ma

I forgot to mention 2 things about the DropBox: 1. You do NOT share any data by accepting an invitation, you only share anything if you specifically go through the Sharing procedure. I think you DO get extra space by accepting an invitation, so it's a win-win situation.2. It is a

If you recommend enough people (who sign up) you can build up to 5Gb free with DropBox. It's a very useful facility. A similar service is offered by 'Box.net', and for a limited time, you can get 50Gb permanent cloud storage for free. However, neither of these options are in any

There are different Arduino boot loaders, these are selected in the Arduino IDE by selecting the board type (Tools -> Board). It may be that you have simply selected the wrong one for your AVR chip. I suggest that if you have selected "Arduino Uno" you try the next one down "Ardu

Thanks, Dave! I will do all of those. I also bought a better pre-fab 232 breakout board today which will be delivered. I had soldered the leads from a usb-rs232 patch originally and it seems to be fine but I don't have a good way to debug it. So, assuming whatever I buy should wo

No, I am sorry. It's just a regular breadboard. I bought the chips with the Arduino bootloader installed from SparkFun. I have other Arduino stuff though and would definitely recommend the prefabricated boards if you're considering buying one. On Mon, Oct 24, 2011 at 12:49 AM, Jo

Hi Matt, My first thought looking at your image is that you have no capacitors fitted to the crystal circuit so you may have an unstable internal reference which may affect the baud rate. With the 16Mhz crystal I would suggest you put in a 22pF cap between each crystal pin and GN
2011-10-23 by Jim Wagner
No, the internal pullups are just a little too large. The issue is speed. The clock and data rise times are entirely set by line capacitance and resistor value. If you are willing to run slower than maximum speed, then you probably could manage with the internal pullups. Jim Wagn
2011-10-23 by tim gilbert
That depends, if you're writing all your own code you could make it work but if you're using any standard I2C parts you will almost certainly need the 3.9K resistors to meet the timing. Regards, Tim Gilbert JEM Innovation Inc. 303-926-9053 (office) 303-437-4342 (cell) www.jeminno

You probably don't need to run off the same power supply but, if by 'two wire' you mean I2C-like, then you do need the same ground (and don't forget the pull up resistors). There's no reason this won't work on a breadboard using DIP components. Been there done that (probably befo

Fo9r old or young, experienced and inexperienced, Breadboards are a great way to develop and test something. What I don't agree with is the statement that you MUST have the same power and grounds. Proper design will allow this to be partly or completely ignored. Let us know just
2011-10-23 by Dave McLaughlin
They can have separate supplies if you need this capability. You just need to connect the GND of each to get a common voltage point. Use the same voltage of supply at each board and use good decoupling at the power entry points of the board and close to the processor power pins.
