Method Detail

createStatusDataPublishedByHardware

public static StatusDataPublishedByHardware createStatusDataPublishedByHardware(PieceOfHardware device)

Creates an object to be published on the STATUS bus by a PieceOfHardware.

Parameters:

device -

Returns:

createStatusDataPublishedByEPOSController

public static StatusDataPublishedByEPOSController createStatusDataPublishedByEPOSController(EPOSController ctlr)

Creates an object to be published on the STATUS bus by an EPOSController.

Parameters:

ctlr -

Returns:

binaryToHex

public static String binaryToHex(String bin)

Parameters:

Returns:

hexToBinary

public static String hexToBinary(String Hex)

The String argument represents an integer in hexa. This methods returns a string representation of this integer argument as an unsigned integer in base 2.

Parameters:

Hex -

Returns:

the binary form of this integer with 8 digits examples : HexToBinary(4) returns 00000100 HexToBinary(AA) returns 10101010 HexToBinary(FF) returns 11111111

twoBytesInHexaToBinary

public static String twoBytesInHexaToBinary(String twoBytesInHexa)

The String argument represents an integer in hexa. This methods returns a string representation of this integer argument as an unsigned integer in base 2.

Parameters:

twoBytesInHexa -

Returns:

the binary form of this integer with 16 digits examples : twoBytesInHexaToBinary("4") returns 0000000000000100 twoBytesInHexaToBinary("AA") returns 0000000010101010 twoBytesInHexaToBinary("FFFF") returns 1111111111111111
