    # ----------------------------------------------------------------------- #
    # If you need to build a complex message to send, you can use the payload
    # builder to simplify the packing logic.
    #
    # Here we demonstrate packing a random payload layout, unpacked it looks
    # like the following:
    #
    # - a 8 byte string 'abcdefgh'
    # - a 32 bit float 22.34
    # - a 16 bit unsigned int 0x1234
    # - another 16 bit unsigned int 0x5678
    # - an 8 bit int 0x12
    # - an 8 bit bitstring [0,1,0,1,1,0,1,0]
    # - an 32 bit uint 0x12345678
    # - an 32 bit signed int -0x1234
    # - an 64 bit signed int 0x12345678

    # The packing can also be applied to the word (wordorder) and bytes in each
    # word (byteorder)

    # The wordorder is applicable only for 32 and 64 bit values
    # Lets say we need to write a value 0x12345678 to a 32 bit register

    # The following combinations could be used to write the register

    # +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #
    # Word Order - Big                      Byte Order - Big
    # word1 =0x1234 word2 = 0x5678

    # Word Order - Big                      Byte Order - Little
    # word1 =0x3412 word2 = 0x7856

    # Word Order - Little                   Byte Order - Big
    # word1 = 0x5678 word2 = 0x1234

    # Word Order - Little                   Byte Order - Little
    # word1 =0x7856 word2 = 0x3412
