WebThe memory element defines the memory range used to calculate the crc and the access method to this memory range if byte swapping is needed. The bytes at the range boundaries are included into the crc calculation. WebExtend the bitarray from bytes, where each byte corresponds to a single bit. The byte b'\x00' maps to bit 0 and all other characters map to bit 1. This method, as well as the unpack method, are meant for efficient transfer of data between bitarray objects to other python objects (for example NumPy's ndarray object) which have a different memory ...
