arduino-volume2's Issues

vol.delay() not completing

It appears that the call to vol.delay() is not working. This can be seen in the example sketches. In wave_types, for example, the sketch does not get past setting the first frequency. Hacking around a bit seems to point to an issue setting toneMillis.

Replacing vol.delay(n) with delay(n * 64) in the example sketches resolves the issue, and produces tones as expected.

I've tried the lib with an Arduino Uno, Duemilanove and Pro Mini.

Consider the Output Compare Modulator (OCM1C0A) on the Mega

On the ATMega2560 and ATMega32U, there's an Output Compare Modulator (OCM1C0A) that does this modulation in Hardware, however it is limited to just the Arduino Mega digital pin 13.

If you configure the timers for OCR1C and OCR0A PWM output, you get hardware modulation of the two timers on the shared PB7/OC1C/OC0A pin.

Arduino Nano support

Hello,
First thank you for this great project, really helpful !!!!! 😄
I a newbie in Arduino so sorry if my question is not relevant.
Is there a way to use this library on a Nano board ?? I cant seem to find any info on this.

thanks a lot

no alternate pin implemented

Hi Connor,

it seems neither the github repo nor the library downloaded by the Arduino IDE actually contain code which contains a way to change the pin, as mentioned in the README.
Is it possible that you forgot to push some commits?
Or is the volume2 library defective anyway, at the moment?

cheers, and thanks!
