Documentation
lightOn :: Bool
The bit value that would indicate the LED is on or off. The actual value is depended on the polarity of the LED and how it was wired.
lightOff :: Bool
stringToMatrix :: String -> [[Bool]]
Convert a string to the matrix representation.
concatMatrixWithSeparator :: [[Bool]] -> [[Bool]] -> [[Bool]]
Concat two nested lists into one nested list
trimZeros :: [String] -> [String]
Trim the extra columns of zeros
toBoolGrid :: [String] -> [[Bool]]
Convert a nested list of Int of 0s and 1s into Bool where 0 to True and 1 to False.
toIntGrid :: [[Bool]] -> [String]
Convert a nested list of Bool to Int of 0s and 1s where True to 0 and False to 1.
letterToMatrix :: Char -> [[Bool]]
Convert a char to the matrix representation in Bool format
charToStrings :: Char -> [String]
Convert a char to the matrix representation in the string format.
specialStrings :: String -> Maybe [[Bool]]
A set of special strings that would map to different text
rawCharToStrings :: Char -> [String]
The char lookup table
