Megadrive pad Arduino uno Code via Unojoy

hi everyone,

i tried out few codes found on net nothing seems work (for me).
either have buttons in state or (high: start /low b c) not together.

every pin of db9 pad in digital inputof uno (except pin 0 & 1)
pin 5:+5v
pin 8: ground

pin 7 select button (as output).

anyone have idea ?

thanks

ok found out !

i used code :

code: [select]

[#include "unojoy.h"

int = 2;
int down = 3;
int left = 4;
int right = 5;
int ab = 6;
int slct = 7; //setting pin high/low reads a/b , start/c
int startc = 8;

void setup() {
  (int = 2; <= 6; += 1){
    pinmode(i, input);
  } //pins 1-6 inputs
  pinmode(slct, output); //'select' pin output
  pinmode(startc, input);
  setupunojoy();
}

void loop() {
  dataforcontroller_t controllerdata = getcontrollerdata();
  setcontrollerdata(controllerdata); //unojoy loop taken example sketch
}

dataforcontroller_t getcontrollerdata(void) {
  dataforcontroller_t controllerdata = getblankdataforcontroller();
  digitalwrite(slct, low); //set 'select' low read , start
  controllerdata.squareon = !digitalread(ab); //uj data inverse of pad data
  if (digitalread(startc) == low && digitalread(up) == low) {
    controllerdata.homeon = high; //start , home button
  }
  else {
    controllerdata.homeon = low;
    controllerdata.dpadupon = !digitalread(up);
    controllerdata.starton = !digitalread(startc); 
  }
  if (digitalread(startc) == low && digitalread(down) == low) {
    controllerdata.selecton = high; //start , down select button
  }
  else {
    controllerdata.selecton = low;
    controllerdata.dpaddownon = !digitalread(down);
  }
  digitalwrite(slct, high); //set 'select' high read b , c
  controllerdata.dpadlefton = !digitalread(left);
  controllerdata.dpadrighton = !digitalread(right);
  controllerdata.crosson = !digitalread(ab);
  controllerdata.circleon = !digitalread(startc);
  return controllerdata;
} /code]

but have create unojoy folder containing unojoy.h in library folder follows:
\mydocs\arduino\libraries\unojoy\unojoy.h

next configure inputs in emulator(i personnaly prefer kega fusion: great video , sound options) , you're ready go !

good retro gaming ;)
