WII U RASPBERRY PI 3 FINISHED

My finished WII U raspberry pi

Features:
Original WII U shell
ON/OFF Push button to power up and down + automatic system shutdown when low battery using lipopi script from Daniel Bull
Front blue power on indicator
Low, charging and charged Battery indicator
Micro USB charging port
Headphones Audio jack with automatic speaker disconnection
Front USB port
Volume control
External SD card reader at the bottom
2x analog joystick
1x D pad
14x buttons

What is inside:

RPI3
USB DAC SOUNDCARD
TEENSY 2.0
CHARGING CIRCUIT
POWERBOOST 1000 BASIC
6.5" HDMI DISPLAY
BATTERY 2x PANASONIC 3400mAH
BATTERY PROTECTION CIRCUIT 8A
2x3 W D-class amplifier
Flat FPC HDMI Cable
FPC to DIP adapters for connecting original controls

Technical details:

Running time is about 3 hours tested on N64.
Total current draw from batteries is around 1.7A
( 1.1A LCD + RPI+ ACCESORIES and 0.6A losses on powerboost )
This is a real life performance but might draw even more when RPI is maxed out.

Teensy Update:

For better analog input in N64 games change any instances of 1.8 like in here " rX = (rX - 512) * 1.8 + 512; " to 1.5.
The analog range is going to be shorter hence joystick is not so sensitive. Retropie is still able to register analog on setup screen but unfortunately you will loose analog movement in psx games. Crash bandicoot is not running anymore :(
Added ESC key for home button to teensy code.

Teensy Update 2:

Home button action modified to switch between Joystick and Keyboard. Now usable in Amiga emulator. Joystick buttons reassigned to match actual wiring.

Code: Select all

const int  MODE = 15;    // the pin that the pushbutton is attached to
const int LED = 11;

int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;

void setup() {


  pinMode(0, INPUT_PULLUP);       // 01 Left Shoulder
  pinMode(1, INPUT_PULLUP);       // 02 Lelf Trigger
  pinMode(2, INPUT_PULLUP);       // 03 Right
  pinMode(3, INPUT_PULLUP);       // 04 Left
  pinMode(4, INPUT_PULLUP);       // 05 Up
  pinMode(5, INPUT_PULLUP);       // 06 Down
  pinMode(6, INPUT_PULLUP);       // 07 B
  pinMode(7, INPUT_PULLUP);       // 08 A
  pinMode(8, INPUT_PULLUP);       // 09 Right Trigger
  pinMode(LED, OUTPUT);           // LED
  pinMode(12, INPUT_PULLUP);      // 13 Start
  pinMode(13, INPUT_PULLUP);      // 14 Select
  pinMode(14, INPUT_PULLUP);      // 15 Y
  pinMode(MODE, INPUT_PULLUP);    // HOME Button
  pinMode(18, INPUT_PULLUP);      // 19 Left Joystick Button
  pinMode(19, INPUT_PULLUP);      // 20 Right Joystick Button
  pinMode(22, INPUT_PULLUP);      // 23 Right Shoulder
  pinMode(23, INPUT_PULLUP);      // 24 X

//  Serial.begin(9600);

Really really nice!!!!

Wondering if you sacrificed a working wii u controller for this........

Great work here [mention]banjokazooie[/mention]!
Would you mind posting some tips or hurdles you encountered during this, that would help someone working on the WII U Gamepad?
