我如何在python中使用serial.readline（）函数的值

Question

import serial
ser=serial.Serial('/dev/ttyACMO',9600)
while 1:
      ser.readline()

I am getting output of my sensors on python like

X=316 O=418

can you help me to use these values 316 and 418?

Answer 1

do you want the following?

import serial
ser=serial.Serial('/dev/ttyACMO',9600)
while 1:
      x_value, o_value = ser.readline().split(" ")
      x_value = x_value.split("=")[-1]
      o_value = o_value.split("=")[-1]
      print o_value, x_value

ValueError: empty separator

Well, it usually means you're parsing a line that does not match the splits we're trying to do, you may want to try this instead:

import serial
ser=serial.Serial('/dev/ttyACMO',9600)
while 1:
      value = ser.readline().split(" ")
      if " " in value:
      x_value, o_value = value
      if "=" in x_value and "=" in o_value:
          x_value = x_value.split("=")[-1]
          o_value = o_value.split("=")[-1]
          print o_value, x_value
      else:
          print value
