Tkinter/Label/Arduino/ if Else condition - emrebt39 - Oct-20-2017
from Tkinter import *
root = Tk()
def connectToArduino():
arduino = serial.Serial(arduinoPort, serialTransferRate)
arduino.timeout = None
time.sleep(2)
arduino.write("S\n")
lab=Label(root, text="Connected")
lab.grid()
return arduino, lab
lab.config(text="Disconnected")
arduino = connectToArduino()
arduino.pack()
root.mainloop()When Arduino Connected serial to PC,Label has Connected MSG.When discomnected,MSG is disconnected.How could i make if Else condition about Connected or Disconnected messages in Label?
RE: Tkinter/Label/Arduino/ if Else condition - Larz60+ - Oct-20-2017
Send a request (ping) to the arduino to which it will respond if connected
If you get a response, just make sure it's not a timeout, and you have your
trigger for messages.
