问题描述
我正在通过串口从一块硬件读取16位整数。
I'm reading 16-bit integers from a piece of hardware over the serial port.
使用Python，我怎样才能使LSB和MSB正确，以及让Python明白它是一个16位有符号整数，我正在摆弄，而不只是两个字节的数据？
Using Python, how can I get the LSB and MSB right, and make Python understand that it is a 16 bit signed integer I'm fiddling with, and not just two bytes of data?
推荐答案
尝试使用模块：
import struct
# read 2 bytes from hardware as a string
s = hardware.readbytes(2)
# h means signed short
# < means "little-endian, standard size (16 bit)"
# > means "big-endian, standard size (16 bit)"
value = struct.unpack("<h", s) # hardware returns little-endian
value = struct.unpack(">h", s) # hardware returns big-endian
