Constructor & Destructor Documentation

SID::SID

(

)

Description

Contructor that creates an instance of the SID object that contains three SIDVoice objects. V1, V2, V3 These objects are used to interact with and control the registers for the SID hardware implemented inside the Papilio FPGA board. Calling this contructor will initialize the SID and SIDVoice objects to their default values.

Syntax

SID()

Parameters

none

Example

#include "SID.h"

SID sid;

void setup()
{
    sid.setVolume(15);
    sid.V1.setInstrument("Calliope",0,0,15,0,0,0,0,1,0); //Calliope
    sid.V2.setInstrument("Accordian",12,0,12,0,0,0,1,0,0); //Accordian
    sid.V3.setInstrument("Harpsicord",0,9,0,0,0,1,0,0,512); //Harpsicord
    sid.V1.setNote(51, 1);
    sid.V2.setNote(51, 1);
    sid.V3.setNote(51, 1);  
}

void loop() {}

Member Function Documentation

void SID::reset

(

)

Description

Set all SID registers to their default values.

Syntax

sid.reset()

Parameters

none

Example

#include "SID.h"

SID sid;

void setup()
{
    sid.reset();
}

void loop() {}

void SID::setVolume

(

byte

volume)

Description

Set the SID master volume

Syntax

sid.setVolume(volume)

Parameters

volume

number between 0 and 15

Example

#include "SID.h"

SID sid;

void setup()
{
    //Turn volume to the max value
    sid.setVolume(15);
}

void loop() {}

void SID::writeData ( unsigned char  address, unsigned char  data  )

static

Description

Use this public function to bypass the SID and SIDVoice functions and write directly to the registers of the SID hardware. Look at the SID datasheet for the registers (http://www.waitingforfriday.com/index.php/Commodore_SID_6581_Datasheet#SID_Control_Registers)

Syntax

SID::writeData(address, data)

Parameters

address	the address from the SID datasheet for the register you want to write to.
data	what you want to write to the SID register

Example

#include "SID.h"

SID sid;

void setup()
{
    //This will set Voice 1 Freq Lo to 0
    SID::writeData(0, 0);
}

void loop() {}
