tone() error compiling to board

Projects Programming

First time posting here.

I am receiving an error when using the tone function in a small sketch that uses an HC-SR04 to determine distance; if it is below a minimum, a tone is generated. I have used the HC-SR04 and piezo in separate sketches with no problems; however, when I put them together, I get the following error:

exit status 1
Error compiling for board
Arduino/Genuino Uno

I traced the problem to one statement in the sketch: tone(8, toneVal);. If I comment out this line the error disappears.

The arduino reference says that tone() interferes with pins 3 and 11, but I'm not using either in my sketch.

I hope someone here can explain where my error lies and how to correct it. The sketch in question is attached, and please note that the tone() function is currently in an uncalled function while I work on the sketch.

Thanks for the help,

Bob

I get the following error:

exit status 1

It says a whole lot more than that

If you look at the entire error message, both the NewPing library and tone() are trying to use Timer2 which causes a conflict.

As a work-around, the NewPing author had developed an alternative to tone() that doesn't use Timer2.

Thank you for your quick reply. I suspected there was a conflict, but wasn't sure where. I appreciate the knowledge!

AWOL:

I wasn't sure what you were talking about, until I went back and scrolled up the entire error msg. Ha! Lots of info there, but I hadn't seen it. I guess that's what I get for using a samsung netbook, with its tiny screen, for compiling arduino sketches. Thanks for the tip, even if it was a bit cryptic at first :wink:

@blh64, does this teckel12 / Arduino New Tone / wiki / Home — Bitbucket works with microbit board? I have encountered error as follows:

I think that's your problem.
