31  Community / Bar Sport / Re: Where to get a Due or Raspberry Pi for Xmas gift on: November 30, 2012, 05:17:46 pm
I successfully ordered another Raspberry Pi from Newark (USA) yesterday. I have a tracking number so it's on its way.
Thanks a bunch - ordered one from newark canada.

Unless there's a special reason that it HAS to be a  Due, or (shudder), Pi....
I dunno, I was assuming the relative had asked for a Due or Pi.

The relative in question is an experienced arduino user and a gadget freak.  He doesn't need another processor, this is a "for fun" thing - the Pi and the Due are the "ooh shiny" of the moment.

As a christmas gift I'd like to get a relative either a due or a raspberry pi but everywhere I look seems to be back ordered.  Are these actually available or are they just trickling out?

I'm in Canada by the way.

Is there a way to move from the beginning to end of a code block (or vice versa) matching braces?

Can you show some simple examples of code using the library?

The arduino language is really c++. I worked my way thru a c/c++ tutorial nook running the examples on the arduino. The biggest things i noticed were the use of setup/loop instead of main and the lack of standard stream i/o on the arduino.
37  Development / Suggestions for the Arduino Project / Re: Interest in overhauling the IDE user interface? on: September 11, 2012, 02:49:32 am
Two things i would like to see:
1) the board and port settings stored kept individually to the ide window and stored with the sketch.
2) a list of recently used sketches on the file menu
Oh, and
3) the hex file kept in the sketch folder.

Interesting idea. Maybe more like a debugger. The higher-end ides like visual studio do some of this.

I can recommend brey terminal as a more capable monitor but it is still a stream of text.

Wow!

Could you reduce the number of pins dramatically by using something like spi?

Post a schematic and the scope trace.  What output do you get from your code and from the mini-tach.
42  Using Arduino / Displays / Re: SparkFun 5110 84x48 LCD supply voltage on: August 20, 2012, 07:25:29 am
I run mine at 3.3 using a small red led to drop the voltage. The current draw is very small so the led's barely visibly lit.
43  Using Arduino / Programming Questions / Re: External Interrupt ISR Execution Latency on: July 23, 2012, 11:39:06 am
There's an excellent writeup linked to by a thread On this site - search for interrupt latency maybe. I believe the basic answer is several microseconds but there are ways to improve it.

I still don't quite believe this but the documentation for 1.0 sounds like the pullups are *not* active for pinMode(INPUT).
They are not active by default. They can be activated, using digitalWrite(). Or, the call to digitalWrite() is made for you if you use the type INPUT_PULLUP.

Whew, thanks.

I think that the "disabled" in that sentence refers to the fact that there is now a call to digitalWrite() in the pinMode() function. It is called with HIGH or LOW based on the use of INPUT_PULLUP vs. INPUT.

A peak at the code confirms this. The digitalWrite() function isn't actually called, but the equivalent register manipulations occur.

Where can I find info about "Hardware features" like the internal resistor, i guess it is not the only hardware feature on the board?
Start here: http://arduino.cc/en/Main/Hardware
Pick whichever board you have, and read all the details, even if you don't think you will use them (yet).

I still don't quite believe this but the documentation for 1.0 sounds like the pullups are *not* active for pinMode(INPUT). This would break a lot of my http://arduino.cc/en/Reference/PinMode
