A chiptune Synthesis Library for Arduino

duinotune's Issues

set_pin() Doesn't affect the output pin

I see you have a set_pin() function, however this doesn't seem to do anything. It isn't included in the tinytune.h file, so it is necessary to manually include it, and after this is done nothing happens to the output when the function is called. Would it be possible for you to fix this/add support for changing the output?

void set_pin(int pin, bool val) {
	PORTB = (PORTB & ~((char)(1 << pin))) | ((val ? 1 : 0) << pin);
}

Thanks for such an amazing library, I hope to see more improvements coming!

Implement simple sampling ability

Add a wavetable instrument type. Short waves could add a lot of sonic possibilities.

Stretch goal - add DPCM sound encodings https://en.wikipedia.org/wiki/Differential_pulse-code_modulation

Sound doesn't output on Mega 2560 board

It actually doesn't even compile, due to the defines missing definitions for the board. After working around that, it compiles, but doesn't output any sound. It does still work just find on my Uno board.

Possible to change output pin?

Hi, is it possible to change the output pin on the Leonardo? (Atmega32U4)

I assume it's stuck to pin 3 for some special interrupt-related reason but is there any other pin on the chip that can be used if the library was modified somehow? I ask because unfortunately pins 2 and 3 are also SDA and SCL on the Atmega32U4, and I need to use the I2C line for an I2C LCD. Is there just no way to do both on that chip?

Add better API for playing instruments directly from sketches.

Currently volume envelopes, pitch glides, and other effects are only supported in converted song playback.
Add an api to allow instruments with envelopes and other effects to be played with commands from arduino sketches.

Add callbacks for beat/note events. Add polling function to read the playback buffer and get a volume level for LED Volume meter sorts of applications.

define note pitches

Add song-creation guide

Add a dedicated document to go over the song creation/import process.

Implement Pitch Envelopes.

Pitch envelopes are supported in renoise and can be used for a lot of cool effects. E.g. tom drums could be approximated with a rapidly swept down square wave.

Digital Pin for Arduino MEGA 2560 is 4 and not 3

Hi,
Could you update the documentation to reflect that for the Mega 2560 the pin is digital pin 4 and not pin 3. In the library code below it appears as if port PORTG5 (pin4) is used.

Thanks

#if defined(ATmega2560)
// This is NOT the sample clock. it is the continuous 62.5khz pwm.
TCCR0A = (1 << COM0B0 ) | (1 << COM0B1 ) | (1 << WGM01) | (1 << WGM00); // Fast PWM & Set OC0B on Compare Match
TCCR0B = (1 << CS00); // No prescaler pck/1
DDRG = (1 << PORTG5); // Output on pD0 (pwm 3 on arduino)
#endif
