Other / TI84+ soundchip - arduino SID emulator

« on: January 14, 2013, 01:20:26 pm »

I finally made this! It's a breadboard arduino running a sid emulator and a link protocol. You can write to registers in the emulated SID chip. It's very user friendly. Now it's possible to have ingame music and soundeffects without terrible framerate drops.

I need to clean up the source, so that's up for download tomorrow.

Spoiler For Spoiler:

Code: [Select]

#include <SID.h>

#define SOUND 1
#define MIDI 0

// MACROs
#define PIN2H (PIND & 0B00000100)
#define PIN3L !(PIND & 0B00001000)

#define CLR(x,y) (x&=(~(1<<y)))
#define SET(x,y) (x|=(1<<y))

SID mySid;

void setup()
{
  pinMode(2,INPUT);
  pinMode(3,INPUT);
  mySid.begin();
}

int n=0;
int timer=0;
int count=0;
int dcount=0;
byte get=B00000000;
int addrval[3] = {0,0,0};


    #define CHANNEL1  0
    #define CHANNEL2  7
    #define CHANNEL3  14


void loop()
{
  do{
    do
    {
      if (PIN3L)
      {
        if (PIN2H)
        {
          CLR(get,count);
        }
        else
        {
          SET(get,count);
        }
        count++;
        
        while(PIN3L)
        {
        timer++;
          if (timer==500){
            n=count=0;
            break;
          }
        }
        timer=0;
      }
    }while(count!=8);
    addrval[n]=get;
    n++;
    count=0;
  }while(n!=2);

  mySid.set_register(addrval[0], addrval[1]);
  n=0;
}

"with 6 buttons, powered by a pic18f46k20 and has 6 buttons"
*writes it down* This is obviously very important
How big is it gonna be?
