NewTone Library - Plug-in replacement for Tone library - Better, smaller, faster

[Vantuil]

Hello, I know it's an old topic, but I use the NewTone library a lot, the audio quality is flawless, I'm using it in a project with arduino nano, it's a variometer for flying, but I'm having a problem locking with it, I have only 1 pin available to turn on the speaker, so I did not use the toneAC, with the tone library works however the sound has a poor quality it gets distorted, I believe the problem is with TIMER 1, I would like to know if you have a way to modify the NewTone library to use TIMER 2, I believe this could solve the problem, is it possible?

Why another tone library?
I'd already written a highly optimized toneAC library because I needed higher volume, volume control, higher frequency, and better quality.  However, toneAC uses fixed timer 1 PWM pins so it's not as flexible.  Making toneAC work like tone was simple and there would be several advantages over the tone library, so I spent an hour and made NewTone from the toneAC library.

What does it do better/differently?

• About 1,200 bytes smaller code size than the Tone library.
• Faster execution time.
• Exclusive use of port registers for fastest and smallest code.
• Higher quality sound output than tone library.
• Uses timer 1 which may free up conflicts with the tone library.

How do I use it?
It's a plug-in replacement for the standard tone library.  Add the include, use NewTone() instead of tone() and noNewTone() instead of noTone() to enjoy the benefits.  If you're running out of program space or have a timer conflict with the tone library, this is the library for you.  See the sketch below for an example.

Download: NewTone v1.0

If you're looking to save even more space and more features like almost twice as loud output and volume control, check out my toneAC library as well.

Example sketch

Code: [Select]


#include <NewTone.h>

#define TONE_PIN 2 // Pin you have speaker/piezo connected to (be sure to include a 100 ohm resistor).

// Melody (liberated from the toneMelody Arduino example sketch by Tom Igoe).
int melody[] = { 262, 196, 196, 220, 196, 0, 247, 262 };
int noteDurations[] = { 4, 8, 8, 4, 4, 4, 4, 4 };

void setup() {} // Nothing to setup, just start playing!

void loop() {
  for (unsigned long freq = 125; freq <= 15000; freq += 10) { 
    NewTone(TONE_PIN, freq); // Play the frequency (125 Hz to 15 kHz sweep in 10 Hz steps).
    delay(1); // Wait 1 ms so you can hear it.
  }
  noNewTone(TONE_PIN); // Turn off the tone.

  delay(1000); // Wait a second.

  for (int thisNote = 0; thisNote < 8; thisNote++) { // Loop through the notes in the array.
    int noteDuration = 1000/noteDurations[thisNote];
    NewTone(TONE_PIN, melody[thisNote], noteDuration); // Play thisNote for noteDuration.
    delay(noteDuration * 4 / 3); // Wait while the tone plays in the background, plus another 33% delay between notes.
  }

  while(1); // Stop (so it doesn't repeat forever driving you crazy--you're welcome).
}

I also have a tone library that doesn't use any timers at all (TimerFreeTone), for just such a situation.

Dear Tim,
In advance, English is not my native language 

First, thanks for sharing the NewTone-code.
One question you might be the perferct person for and you might be able an willing to help:

Do you know how to get a frequency in decimals? For instance 78,5Hz or 7,85Hz
As far as I see with NewTone I can use integer only.

Thanks,
Ed

Simple answer, you can't, as it's integer-based only.

Hi


I have used the library in Arduino, it works great.

Now I´m triying to use it in mbot graphical mode for Arduino.

This is the code generated by the app



#include <Arduino.h>
#include <Wire.h>
#include <SoftwareSerial.h>

#include <NewTone.h>
double angle_rad = PI/180.0;
double angle_deg = 180.0/PI;

void setup(){
    pinMode(13, OUTPUT);
    for(int __i__=0;__i__<3;++__i__)
    {
        NewTone(13, 262, 500);
        delay(500*4/3);
        _delay(1);
    }
}

void loop(){
    _loop();
}

void _delay(float seconds){
    long endTime = millis() + seconds * 1000;
    while(millis() < endTime)_loop();
}

void _loop(){
}


I dosent work I have this mesage

Arduino\hardware\arduino\avr\libraries\NewTone/NewTone.cpp:14: multiple definition of `__vector_11'


Do you have any idea whats gooing on?

Thanks a lot

Yes, I do have an idea on what is going on, the error says it: multiple definition of `__vector_11'

Have you visited the NewPing repo, which provides help on common issues? It's here:

https://bitbucket.org/teckel12/arduino-new-ping/wiki/Home

Specifically, the above error (albeit a different number in your situation) is addressed. This is a classic Arduino error that means two libraries are attempting to use the same timer. It's not specific to NewPing at all. The solution is also given on the support page above.

Thank a lot for the answer!

I will read the documentation.

Hi !

As a newbie just started with Arduino programming, I am trying to get the NewTone library working.

Besides the standard 'Tone', I need a second independant tonegenerator. Was hoping to be able to use the NewTone for this (because it uses the second timer), but cannot get it compiling.

Getting a lot of compiler errors as below:

\libraries\NewTone\NewTone.cpp:15:27: error: 'CS10' was not declared in this scope
  uint8_t prescaler = _BV(CS10);                 // Try using prescaler 1 first.
                          ^
\hardware\teensy\avr\cores\teensy3/core_pins.h:47:22: note: in definition of macro '_BV'
#define _BV(n)  (1<<(n))
                     ^
\libraries\NewTone\NewTone.cpp:18:21: error: 'CS12' was not declared in this scope
    prescaler = _BV(CS12);                       // Set the 256 prescaler bit.
                    ^
\hardware\teensy\avr\cores\teensy3/core_pins.h:47:22: note: in definition of macro '_BV'
#define _BV(n)  (1<<(n))
                     ^
\libraries\NewTone\NewTone.cpp:31:3: error: 'ICR1' was not declared in this scope
  ICR1    = top;                     // Set the top.
  ^
\libraries\NewTone\NewTone.cpp:32:7: error: 'TCNT1' was not declared in this scope
  if (TCNT1 > top) TCNT1 = top;      // Counter over the top, put within range.
      ^

- Is this library compatible with the Teensy 3.2 ?
- What am I doing wrong ?

Thanks !

Arduino libraries are typically designed for use ATMega processors unless otherwise noted.  Also, any library that uses timers won't work with a Teensy.  So no, it's not compatible with the ARM Teensy processor.

The Teensy 3.2 doesn't has totally different timers and far more sophisticated ones.  You should investigate how to generate tones or music on the Teensy specifically, not look for an Arduino solution which will only work with Arduino processors.
