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]]])
