Yes, I would also like a native Gambas component for i2c and GPIO (not
Take a quick look at my code on the Gambas Farm "gb.PiconZero", I wrote
a very basic i2c (via shell) and GPIO class (via shell / gpio sysfs).
Also on github add Setup photos:
If you don't already know, the Gambas Farm is a place where other users
share code and is available directly in the Startup dialog (and Tools >
Software Farm) in the Gambas IDE.
If you plan to write a Gambas Component in C this might help:
