Python:读取/解包12位低端压缩数据的快速方法

import struct

data = b'\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C'
values = struct.unpack('<3H', data)
print(values)  # 输出：(513, 1027, 1541)

from bitstring import BitArray

data = b'\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C'
bits = BitArray(bytes=data)
value1 = bits[0:12].uint
value2 = bits[12:24].uint
value3 = bits[24:36].uint
print(value1, value2, value3)  # 输出：513 1027 1541

import numpy as np

data = b'\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C'
array = np.frombuffer(data, dtype=np.uint16)
value1 = array[0]
value2 = array[1]
value3 = array[2]
print(value1, value2, value3)  # 输出：513 1027 1541
