Description

Simple number guessing game on the OSEPP Keyboard shield.

Thanks to David Palmer for lending me his OSEPP shield to play with!

Synopsis

osepp :: LCDController
data Key
- = KeyRight
- | KeyLeft
- | KeyUp
- | KeyDown
- | KeySelect
initOSepp :: Arduino (LCD, Bool -> Arduino (), Arduino (Maybe Key))
numGuess :: LCD -> (Bool -> Arduino ()) -> Arduino (Maybe Key) -> Arduino ()
guessGame :: IO ()

Documentation

osepp :: LCDController Source #

The OSepp LCD Shield is a 16x2 LCD using a Hitachi Controller Furthermore, it has backlight, and 5 buttons. The hook-up is quite straightforward, using our existing Hitachi44780 controller as an example. More information on this shield can be found at:

data Key Source #

There are 5 keys on the OSepp shield.

Constructors

KeyRight
KeyLeft
KeyUp
KeyDown
KeySelect

initOSepp :: Arduino (LCD, Bool -> Arduino (), Arduino (Maybe Key)) Source #

Initialize the shield. This is essentially simply registering the lcd with the HArduino library. In addition, we return two values to the user:

A function to control the back-light
A function to read (if any) key-pressed

numGuess :: LCD -> (Bool -> Arduino ()) -> Arduino (Maybe Key) -> Arduino () Source #

Number guessing game, as a simple LCD demo. User thinks of a number between 0 and 1000, and the Arduino guesses it.

guessGame :: IO () Source #

Entry to the classing number guessing game. Simply initialize the shield and call our game function.
