    The YDigitalIO class allows you drive a Yoctopuce digital input/output port.
    It can be used to set up the direction of each channel, to read the state of each channel
    and to switch the state of each channel configures as an output.
    You can work on all channels at once, or one by one. Most functions
    use a binary representation for channels where bit 0 matches channel #0 , bit 1 matches channel
    #1 and so on. If you are not familiar with numbers binary representation, you will find more
    information here: https://en.wikipedia.org/wiki/Binary_number#Representation. It is also possible
    to automatically generate short pulses of a determined duration. Electrical behavior
    of each I/O can be modified (open drain and reverse polarity).
