What pins are the I2C ports directly wired to?

I'm trying to replicate r0d0t's Ghost Detector in which he used the I2C ports as direct inputs. I'm using analogRead(27) and analogRead(28) to gather information from the I2C, but I get a lot of static. That's why I'm unsure I have the proper pins. I used the Gamebuino schematic from the wiki to get the pins 27 and 28. Does anyone know what I'm doing wrong? My code:

Code: Select all

#include <Gamebuino.h>
#include <SPI.h>
Gamebuino gb;
const DAT = 27;
const CLK = 28;
float DATA = 0;

void setup(){
  pinMode(DAT,INPUT);
  pinMode(CLK,INPUT);
  gb.begin();
  gb.titleScreen(F("Ghost Detector"));
}
void loop(){
  if(gb.update()){
    DATA = analogRead(DAT)/2 + analogRead(CLK)/2;
    gb.display.drawRect(0,30,DATA,5);
    if(gb.buttons.pressed(BTN_C)){
      gb.titleScreen(F("Ghost Detector"));
    }
  }
}

Did you cut the pull-up jumper to disable it?

No, I didn't. Would that mean desoldering? If anything, I can't solder to save myself. XD. Also, does my code look okay?
