1  Forum 2005-2010 (read only) / Syntax & Programs / Does the Aurdino accept C or C++? on: October 21, 2009, 08:12:47 am
I have a nano 3.0 on the way and was looking at the language reference.  It seems to be written a bit for non-programmers and is confusing me. At one point is sounds like it is a scripting language based on C syntax. I assume it is cross-compiled C then flashed on to the device?

Secondly, Can I write the main program in C++ like the Libraries, understanding that it looks like there is no heap, no "new" and everything is on the stack.

"FWIW, as I recall, in that past the Arduino devs have said they don't intend to support an emulator in the IDE as actual hardware is considered an integral part of project."

That is an extreamly stupid statement for them to make if it is true. Anyone who has programmed micro's knows after the honeymoon you are searching for a way to develop faster without needlessly burning off write cycles. As the arduino provides for much larger programs, the cycle of "make a change, write it, test it, repeat" gets counter productive. (And a good reason people will switch from a stamp, i might add)
3  Forum 2005-2010 (read only) / Troubleshooting / nano power off usb not working on: October 31, 2009, 04:52:04 pm
I just bought a nano 3.0 from gravitech and could not get it to be seen in dmesg and no lights. I powered it up externally and leds lit up so I connected the usb cable and it is seen. Did I just get a defective unit? The same cable powers a picdem2 just fine, so I don't think it is the cable.

Anyone else see this issue with the nano 3.0

The analog ports are numbered wrong in the image on the site.
Unfortunately the a/d inputs on pins labeled a0 and a1 are really A6 and A7. These apparently cannot be used as anything other than analog input. The application I was working on had a basic stamp in here and is using the shiftout trick on those pins. so I am screwed.

This limitation needs to be called out.

I have 3 extra digital outs of course, I am using a tall socket and letting the board overhang, but how to get it over to the other side. This board needs to still take the BS2. :-(

Another unpleasent surprise was that the arduino has .1 pin headers and not pins that can go in a socket.  

If the point was to make for an easy migration for BS2 users, we kinda missed the mark slightly.
5  Forum 2005-2010 (read only) / Interfacing / Automatic Reset on: October 26, 2009, 08:58:23 am
How do I disable the Automatic reset on usb connection?

I chose the nano as a replacement or a Basic Stamp and missed the fact that the tx and rx lines are ttl and not rs232 level like a stamp.  The hardware is already set and the product is to have terminal access thru serial.
usb is ok, except for the darn automatic reset. Since I only need reset during programing, I will have access to the button. Since the device is controlling a charger, I am afraid the reset will cause a relay to drop while under power.
I need to be able to connect, configure, without disrupting operation.
