-- | Haskell interface for controlling the mBot educational robot
--   
--   This is a library to control the mBot robot with haskell. This will
--   only work when you connect the robot with the default firmware over
--   2.4ghz the Bluetooth version is not supported !
@package MBot
@version 0.2.0.0


-- | <h1>Programming the mBot</h1>
--   
--   With this library it is possible to control the mBot robot from within
--   Haskell over 2.4ghz wireless. The mBot itself needs to contain the
--   standard firmware otherwise the library will not behave as expected.
--   There is support for steering the motors and leds and for reading the
--   linesensor and the ultrasonic sensor. An small example program is
--   shown below, for more information about the individual functions take
--   a look at the api documentation below.
--   
--   <pre>
--   import MBot
--   
--   main =  do
--     putStrLn "My first mBot program in Haskell !"
--     -- Open the connection with the mMbot
--     d &lt;- openMBot
--     putStrLn "Opened a connection with the mBot"
--     -- Turn on led 1 of the mBot and set the RGB value to (0,100,0)
--     sendCommand d $ setRGB 1 0 100 0
--     putStrLn "Look at all the pretty colors !"
--     -- Turn on led 2 of the mBot and set the RGB value to (100,0,0)
--     sendCommand d $ setRGB 2 100 0 0
--     -- close the connection with the mBot
--     closeMBot d
--   </pre>
module MBot

-- | Opens a connection with the mBot
openMBot :: IO Device

-- | Close the connection with the mBot
closeMBot :: Device -> IO ()

-- | Sends a mBot command over the HID device
sendCommand :: Device -> Command -> IO ()

-- | Read out the status of the ultrasonic line follower
readUltraSonic :: Device -> IO Float

-- | Read out the status of line follower sensor
readLineFollower :: Device -> IO Line

-- | Create an mBot command for moving the motors
setMotor :: Int -> Int -> Command

-- | Create an mBot command to turn on the led on a particular rgb value
setRGB :: Int -> Int -> Int -> Int -> Command

-- | Contributed by: Rien Maertens Create an mBot command to sound a tone
--   with the buzzer.
playTone :: Int -> Int -> Command

-- | The line sensor consists of two sensors which are able to detect
--   either a black or a white surface. Therefore there are four different
--   states to represent the state of the line sensor
data Line

-- | Left sensor reads black right sensor reads white
LEFTB :: Line

-- | Right sensor reads black left sensor reads white
RIGHTB :: Line

-- | Both the left and right sensor observe a black surface
BOTHB :: Line

-- | Both the left and right sensor observe a white surface
BOTHW :: Line

-- | Type of mBot commands the constructor is not exported.
