Hi El Khiari,

Here is an GPIO example. Set the GPIO number in the Number attribute of the ChanDi or ChanDo. Connect the signals (Do and Di) with the channels (ChanDo and ChanDi) by selecting the channel object and activate 'Connect Channel' in the popup menu for the signal object.

Also add user pwrp to the gpio group.
