|
|| | A Software Digital Square Wave Tone Generation Library

|
|
|| |
|
|
|| | This is a Wiring Framework (Arduino) library to produce square-wave
|
|
|| | tones on an arbitrary pin.
|
|
|| |
|
|
|| | You can make multiple instances of the Tone object, to create tones on
|
|
|| | different pins.
|
|
|| |
|
|
|| | The number of tones that can be generated at the same time is limited
|
|
|| | by the number of hardware timers available on the hardware.
|
|
|| | (e.g. ATmega328 has 3 available timers, and the ATmega1280 has 6 timers)
|
|
|| |
|
|
|| | A simplified (single tone) version of this library has been included
|
|
|| | in the Wiring Framework since Wiring 0025 and in the Arduino distribution
|
|
|| | since Arduino 0018.
