Hi and thanks for your answer,

but then i didn't understand what you try with,
u.set_adc_offset(0, offset0)
u.set_adc_offset(1, offset1)
u.set_adc_offset(2, offset2)
u.set_adc_offset(3, offset3)

As you wrote above, the mask is the bits you want to touch
and the bits is the value you want to store, but why do you
want to store a value of int(2) and int(3).
As i understand you, there are only 2 logically
values for the bits we store int(0) and int(1).

Is this correct ?
