from datetime import datetime
import tkinter as tk

running = False

def update_time():
    """Update the time display"""
    if running:
        time_display.set(datetime.now().strftime('%H:%M:%S'))
        root.after(1000, update_time)  # Scedule myself to run again

def start_stop():
    """Start/stop updating the time display"""
    global running
    running = not running
    if running:
        update_time()

root = tk.Tk()
time_display = tk.StringVar()
tk.Label(root, textvariable=time_display, width=8).pack(padx=10, pady=10)
tk.Button(root, text='Start/Stop', command=start_stop).pack(padx=10, pady=10)
root.mainloop()

This doesn't do anything in you program.

#Set Globals
global pitchLabel
global rollLabel
global yowLabel

Using the "global" keyword only makes sense inside a function. It tells Python to not create a local variable when doing variable assignment.

global_variable=0
def uses_local_variable(value):
    global_variable = value

def uses_global_variable(value):
    global global_variable
    global_variable = value

print(global_variable)
uses_local_variable(5)
print(global_variable)
uses_global_variable(10)
print(global_variable)

Output:
0
0
10

Thank you but as you can see from my reply I worked it out
