Multi Wii Copter LCD Config

About

LCD_Config is a hardware and software solution to programm the Multi Wii Copters on flying field, also it contains the possibility to log data while flying.

You need:

• an Arduino board Arduino Boards
• Arduino 022 (for SD Card support)
• a LCD Display, either using parallel 4 Wires or ShiftReq control (based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs.)
• Some keys, some cable
• latest Arduino Sketch for LCD_Config: http://www.rc-heli-fan.org/download/file.php?id=91727

Features

• works for Multi Wii Software 1.5 (stable) and 1.6 beta
• Communicates to the MultiWii software over serial line like the GUI
• Same parameters changeable as in the GUI
• Output of values for sticks, gyro, acc, and ESCs (excluding graphical views)
• Logging onto SD card

Hardware

LCD Keypad Shield

This is the original LCD used with the LCD_Config app:

Hardware Keys

If you like to use normal hardware keys on digital ports use this schematic to connect them:

http://arduino.cc/en/Tutorial/DigitalReadSerial

Then remove the comment signs // in front of line:

#define HWKEYS 

Define the ports to use here:

// Input pins of the hardbuttons: (used when HWKEYS is defined)
#define HW_RIGHT    10
#define HW_UP        9
#define HW_DOWN     11
#define HW_LEFT      8
#define HW_SELECT    6

It is possible to controll everything with out the Select key, so you don't need this key.

Shift Register LCD

Using 3 wires interface for LCD display:

Adjust the ports used here:

  ShiftRegLCD lcd(3, 2, 4, 2);        // (Datapin, Clockpin, Enablepin or TWO_WIRE [, Lines [, Font]]])

SD card connections

pin 13   SCK   SPI clock   
pin 12   MISO   SPI master in, slave out
pin 11   MOSI   SPI master out, slave in
pin 10   SS   SPI slave select
