1  Using Arduino / Installation & Troubleshooting / Re: Sketches Not Uploading To Mega on: January 18, 2012, 04:12:47 pm
I went back to Arduino version 0022 and that solved the problem for me.  If you're using 1.0, try 0022 or 0023 and see if that works.

I was having this problem too.  Luckily I hadn't erased my old 0022 program.  Going back to that fixed the problem.  I really ought to remember: "Never update a program that works!"

It would be nice if that page had a clear download link.
For math.h? You already have math.h. You don't need to download it.

Oh!  I saw a sketch which had an include statement for math.h and that misled me.  I thought it was an Arduino library and had to be in the "libraries" folder.  Thanks for clarifying.

Don't know how I didn't see that library.
I saw that library referenced once, but not linked to.  It would be nice if that page had a clear download link.
Or if it were in the Libraries section of the Arduino playground, under "math" that would be good too.

The old thread said:

Tlc.analogWrite(channel, value, chip);

Does "set" work that way now?  I mean, does it take three values with chip number being the third value?  (When I try to verify my script, I am told that the current version of the library "has no member named" Tlc.analogWrite).

Can someone with editing priveleges please put the current information on the page for the TLC5940 library?  http://www.arduino.cc/playground/Learning/TLC5940
6  Using Arduino / Installation & Troubleshooting / Re: Unable to see Arduino on COM3 after upgrade on: November 18, 2011, 08:11:37 pm
I have a problem with COM3 also, but I'm using 0022.  Every once in a while COM3 will disappear.  COM4 disappeared and hasn't come back at all.  I mean, COM4 is no longer even listed in the Device Manager.  Is it possible to damage a communications port with the Arduino?  Is this likely a hardware or software problem?

Thanks!
8  Community / Website and Forum / fscale not in math.h? on: November 14, 2011, 02:25:00 pm
I tried using the fscale function from http://arduino.cc/playground/Main/Fscale
It results in an error:
'fscale' was not declared in this scope

As per the instructions, I have "#include <math.h>" at the start of my sketch.  The "get code" link goes to http://arduino.cc/playground/Main/Fscale?action=sourceblock&num=1  which has examples, but no link to a library.  Where is it?  How can I use fscale?
9  Development / Suggestions for the Arduino Project / Re: Please use a better font on: November 08, 2011, 11:37:21 pm
Thanks, Jack.  I can use that.

Still, I think it would be worthwhile to change the standard font to one where no characters are identical.  I mean, changing my prefs won't change how other peoples' code looks online. :-)
10  Community / Website and Forum / Suggest addition to description of 'map' function on: November 08, 2011, 11:30:50 pm
Current version
"Does not constrain values to within the range, because out-of-range values are sometimes intended and useful. The constrain() function may be used either before or after this function, if limits to the ranges are desired. "

Suggested version
"Does not constrain values to within the range, because out-of-range values are sometimes intended and useful.  For example: if the incoming value is below the fromLow value, the outgoing value will be negative in proportion to the given toLow - toHigh range. The constrain() function may be used either before or after this function, if limits to the ranges are desired. "

I didn't know what exactly the map function would do with out-of range numbers.  With a short explanation like this I would have understood immediately.  I think it would be quite helpful to other learners (ok, noobs) like myself.

P.S. the reference page says to post suggestions in the forum and gives a link.  Is this the correct forum?

Thanks! 
I used the Attach function under additional options.  I see now that if I do that I don't use the image tags.
12  Community / Website and Forum / Forum instructions? on: October 30, 2011, 05:11:57 pm
Are the instructions for how to include images posted somewhere?  How about instructions for other stuff?

I tried using the Insert Image button and it only gives the bracketed commands, no instruction on how to use them.  I attached the images, but they don't show up between the brackets.
13  Using Arduino / Sensors / what circuit layout does capsense use? on: October 30, 2011, 05:10:03 pm
Using capsense library with multiple inputs, do you use this layout?


Or this one?


Or something else?

edit:  On the second drawing I meant to have the third input after the resistor.
14  Development / Suggestions for the Arduino Project / Please use a better font on: October 30, 2011, 03:08:58 pm
Easy change to improve the programming interface: use a font where all of the characters are unique.  In the font that's used now, the l and 1 look the same.  There really is no reason to use a defective font.
