Wie kann ich Daten von Python lesen, wenn Sie Arduino verwenden, anstatt CoolTerm zu verwenden?

Question

Ich benutze diesen Code zur Zeit die Daten zu visualisieren ich erfassen mit Coolterm

Sie könnten versuchen, pyserial zu verwenden.

Beispiel:

#!/usr/bin/python 
import serial 

port = serial.Serial("/dev/ttyUSB0", 9600, timeout=1, bytesize=8, 
parity='N',stopbits=1, xonxoff=0, rtscts=0, dsrdtr=0) 
data = port.readline() 
port.close()`
