whatever value of yy , always a nill is given back.If provided the correct address it works fine , but it looks then something was wrong although it isn't
Is this a small bug on arduino due ???
Found the solution !Its somewhere on the ulisp pages.For sam boards , you have to use :(defun scn () (dotimes (p 127) (with-i2c (str p) (when (restart-i2c str) (print p)))))
Now it works !
