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

Hi Thanks for you reply but i have solved it

Width great help from this Forum :-)

http://arduino.cc/forum/index.php/topic,157602.0.html

Thanks Ole

this could be awesome if the library was also Due compatible

TheKitty: this could be awesome if the library was also Due compatible

I don't find the Due relevant, so I don't consider support for it. Also, as NewTone uses port registers and direct timer calls, it doesn't really work well for the Due which is totally different than the ATmega.

teckel: I don't find the Due relevant, so I don't consider support for it.

Supposedly it is the future as they did not stick with a compatible processor. Many have written suitable timer control libraries so the work would not be from datasheet scratch.

Hi, i've some problems using the cool NewTone Library together with RCSwitch-Library (using interrupt on pin 2)

I can play sound several times correctly (always using the same function), and than it suddenly stopps playing any sound, while everything else is working fine. Shure both libs use timers and this will harm the sound quality, but why isn't it working any more? PLZ gibe advice what i'm doing wrong or if there's an workaround.

i'm still on arduino 1.0.1 and i'm using an arduino nano V3. The code isn't pretty..sorry for that.

MANY MANY thanks for your replys

Hi,

I am trying to generate a freq of 1hz till 600khz. I think toneAC can do it but what is the max freq that newtone can generate?

Also can it be used on a Arduino Nano?

Thanks

Roy

I would like to made some music to my robot, but I can't use virtualwire lib with new tone lib because timers is sames for both libraries. I've found another servo lib than original who have same problem. This is fixed. ( it is sofware servo: http://playground.arduino.cc/ComponentLib/Servo)

But not with virtual wire.

Virtual wire use timer1 (16 bits resolution). NewTone lib too.

some informations found about timers here: http://letsmakerobots.com/node/28278

It is possible to unusable or change timer ?

thx

Try my toneAC2 library if you want to use timer 2. Also, the standard tone library also uses timer 2. I wrote NewTone and toneAC to use timer 1 if you were having a timer 2 conflict with something else. If timer 1 is your conflict, use the standard tone library or toneAC2.

Hi Tim, Thanks for your work on the various tone libraries. I'm presently building a device that uses one to drive a speaker to play music. I have a question about usage of timers and outputs. I'd like to keep the possibility open to produce two channels of output (concurrently.) In other words I'd like to play the main melody on one digital output and harmony on another digital output. I also prefer to stick with one output/channel. Is there a tone library or combination of libraries that can do this?

Thanks!

Brilliant! Solves the < 31 Hz problem of the original.

My application: use with a micro-stepping motor driver that has step and direction inputs. This makes variable speed control very easy.

Hi,

Does this library works together with addressable LED strips (NeoPixel library)? Because to get the tight timing needed by the LED strips interrupts are disabled while sending the data. So the original Tone() library doesnt work for me. Wondering if newTone Library works?

Any plans for supporting ATtiny85 (Adafruit Trinket)?

mcmahonrw: Any plans for supporting ATtiny85 (Adafruit Trinket)?

Not sure if it would be possible do to the use of timers. But, I do know that my TimerFreeTone library is compatible with the ATtiny 85 (and just about any other platform as it doesn't use timers).

Hi!

I’m very new to Arduino and electronics. I’m building a capacitive touch morse keyer and I need to generate a 800 to 1200 Hz tone. I still don’t know for sure if a sine wave is needed or a square wave is good enough to TX with a simple LPF.

Does the NewTone() make a square wave output like tone()?

I have found that NewTone(pin, freq) makes a little noise when it’s ended with noNewTone(), but if I set a duration, the tone ends clean.

I would like to code something like this example, but with a fixed duration. Do you have other library that I could use?

Thanks in advance.

Yes, NewTone creates a square wave. The Arduino can't output a sine wave. If you need a sine wave, I would suggest using a Teensy 3.2

If you end a tone early it may stop in the middle of the high state. If it ends on it's own, it always finishes the high state before ending.

I don't understand your last question. You want to code something like what example? NewTone does do a fixed duration so I'm confused.

Tim

Hello Tim!

Thanks for your quick answer.

I have attached in the previous post an example from make magazine that creates a sine wave that never ends. I'm trying to merge your library and this example to generate a sine wave with a fixed duration. As I dont want to abuse of your time ¿Do you know or have something already made that I can use?

For example teensy 3.2 could be an option.

Again Thanks! H

Just so you know, this doesn't generate a sine wave. It creates a simulated sine wave. You could create a sketch that would modify this SineWave sketch and create a function that would play a simulated sine wave at a preset frequency. But, it will still be a simulated sine wave, not an actual sine wave.

Keep in mind that a digital pin can only be on or off. So, no matter the code, that's all it can output. This SineWave sketch doesn't actually produce anything close to an actual sine wave. In other words, if you really need a sine wave, this SineWave sketch isn't going to do it for you.

Tim

Thank you Tim for explaining me so clearly. You have helped a lot and made think about other options.

Certainly not the author's fault, but FYI I attempted to use this as a drop-in replacement for tone in my application and caused a small fire... (I'm driving an inductor/oscillator pretty hard). Not sure if the duty cycle was higher, or it just kept the pin high for too long for some other reason. The only other library i'm using in this sketch is debounce, I don't think there are any timer conflicts there

A timer conflict wouldn't cause it and even if the pin was kept high for a long time it wouldn't cause a fire at 5 volts. Something else is wrong, it's not the software.
