/**
 * YDigitalIO Class: digital IO port control interface, available for instance in the Yocto-IO or the
 * Yocto-Maxi-IO-V2
 *
 * The YDigitalIO class allows you drive a Yoctopuce digital input/output port.
 * It can be used to setup 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).
