Revision as of 02:16, 2 June 2011

This stub is to document the process of trying to get AOA working with older hardware. ie freeduino + spark fun host shield and phones not currently supported.


What I am using

Hardware

  • Freeduino 1.22 with a ATmega328p-pu chip
  • Sparkfun USB Host shield
  • HTC G2

Software


* indicate that I had to change the code to get it to work.

Changes

There are a few changes that have to be made to the stoke software to get this to work.

demokit.pde

Out of the box the Arduino sketch for the demokit will not compile for the ATmega328. There are a lot of pins that are used that do not have the same name or do not exist. 

#include <Wire.h>
#include <Servo.h>

#include <Max3421e.h>
#include <Usb.h>
#include <AndroidAccessory.h>

#include <CapSense.h>

#define  LED2_GREEN     7
#define  LED2_BLUE      6

#define  LED1_RED       8
#define  LED1_GREEN     10

#define  SERVO1         11
#define  SERVO2         12
#define  SERVO3         13

#define  TOUCH_RECV     14

#define  BUTTON1        A6
#define  BUTTON2        A7
#define  BUTTON3        A8

#define  JOY_SWITCH     A9      // pulls line down when pressed
#define  JOY_nINT       A10     // active low interrupt input
#define  JOY_nRESET     A11     // active low reset output

After removing the definitions that are not used. removed all of the functions that control things that will not be used and changed everything to LED/buttons you this is whats left.
