pyserial，当它是行的结尾时，停止while循环

问题描述

import serial

arduino = serial.Serial('COM12', 9600, timeout = .1)
arduino_data = [] # declare a list

while True:
    data = arduino.readline()
    if data:
        arduino_data.append(data) # Append a data to your declared list
        print arduino_data

我想知道从Arduino端不再有新的生产线了，我该如何跳出while循环?

I wonder when there is no more new line from Arduino side, how can i jump out the while loop?

while True:
    data = arduino.readline()
    if data:
        arduino_data.append(data) # Append a data to your declared list
        print arduino_data
        break

仅适用于1行.

推荐答案

等待它超时而没有任何数据，那么您就知道它已经完成了.

Wait for it to timeout without any data, then you know it is done.

例如:

import serial

arduino = serial.Serial('COM12', 9600, timeout = .1)
while True:
    data = arduino.readline()
    if data:
        arduino_data.append(data) # Append a data to your declared list
        print(arduino_data)
    else:
        break
