weird comparison

is this statment [ if((data>>i) & 0x0001 >0) ] same as [ if((data>i) && 0x0001 >0) ] ?

This is no comparison, it is bit shifting and masking :smiley:

No.

is the Shift Right operator and & is the bitwise AND operator.

It's testing bit 'i' of data, equivalent to:

if (data & (1<<i))

..apart from the "greater than zero".
That's a comparison.
