This PiFace menu tutorial keeps it simple @Raspberry_Pi #piday #raspberrypi

Pi face menu

Using his new PiFace, this maker wrote a python script for a 5 option menu for the Raspberry Pi that you can leave running (with an adjustable backlight!), from uktechreviews.

My prototype Python script generates 5 menu options which are accessed via the push buttons. Once pressed they either launch another script or run part of the menu script.

I intend to leave this running so I have included two buttons to switch off the back light and turn it back on again.

The clock option displays the current time for three seconds.

The code is still in development and is rather ‘clunky’ (if you can use such a term!) – but it does work!

Please feel free to use any aspect of the code and modify and improve!!!

import pifacecad
import time

def update_pin_text(event):
event.chip.lcd.write(str(event.pin_num))
choice = event.pin_num
if choice == 0:
cad.lcd.clear()
cad.lcd.write(“Menu selected”)
import subprocess
p = subprocess.Popen([“sysstart”])
output, err = p.communicate()
cad.lcd.clear()
cad.lcd.backlight_on()
cad.lcd.write(“1:Welcome 2:GS\n3:Clock [4/5]:BL”)
if choice == 1:
cad.lcd.clear()
cad.lcd.write(“GSL countdown\nselected”)
import subprocess
p = subprocess.Popen([“GSL2014”])
output, err = p.communicate()
cad.lcd.clear()
cad.lcd.backlight_on()
cad.lcd.write(“1:Welcome 2:GS\n3:Clock [4/5]:BL”)
if choice == 2:
cad.lcd.clear()
cad.lcd.write(“Current time: \n”)
cad.lcd.write(time.ctime())
time.sleep(5)
cad.lcd.clear()
cad.lcd.write(“1:Welcome 2:GS\n3:Clock [4/5]:BL”)
if choice ==3:
cad.lcd.backlight_on()
if choice ==4:
cad.lcd.backlight_off()

cad = pifacecad.PiFaceCAD()
cad.lcd.backlight_on()
cad.lcd.write(“Pi menu Use the \nbuttons”)
time.sleep(2)
cad.lcd.clear()
cad.lcd.write(“1:Welcome 2:GS\n3:Clock [4/5]:BL”)

listener = pifacecad.SwitchEventListener(chip=cad)
for i in range (6):
listener.register(i, pifacecad.IODIR_FALLING_EDGE, update_pin_text)
listener.activate()
