WebMar 28, 2024 · The bitmask module provides two functions that facilitate conversion of bit field arrays (i.e., DQ arrays) to boolean masks: bitfield_to_boolean_mask converts an input bit field array to a boolean mask using an input bit mask (or list of individual bit flags) and interpret_bit_flags creates a bit mask from an input list of individual bit flags. WebBitfields are for giving names to parts of a byte (or bigger integer type). As long as controllers arr 8-bit, 16-bit or wider, C can't point to a single bit in any portable fashion.
