ArduinoProgrammableSoundGenerator

An Arduino NES inspired multichannel sounds generator library.

How to use it

Plug a speaker to pin 3, then init the sound generator in the setup function.

#include "APSG.h"

void setup()
{
  init_SID();
}

Play a 440Hz triangle wave for 1 second, then stop.

triangle.note = N_A4;
delay(1000);
triangle.note = N_NOP;

Play 2 tones at the same time.

squares[0].note = N_A4;
squares[1].note = N_A5;

Set volume for specific channel to maximum.

noise.volume = 15;

Sweep a channel down to low frequency.

sawtooth.sweep_direction = SWEEP_DOWN;
sawtooth.sweep_shift = 1;
sawtooth.sweep_speed = SWEEP_SPEED(8);

There are other examples in the ino file. For instance, a couple of multichannel melodies. Try them out!
