Returning LCD keypress

[noven]

I'm working on some code to cycle through functions on the LCD using buttons. This works perfectly for simple one line commands. But when I need to call another function I wish one keypress to exit the loop AND pass that same keypress back to the menu function to cycle.
Snippet:

Code: Select all

def pident():
    while True:
        hostname = subprocess.check_output("hostname")
        hostip = subprocess.check_output("ip addr show eth0 | grep 'inet ' | awk '{ print $2}'", shell=True)
        lcd.backlight(lcd.WHITE)
        lcd.clear()
        lcd.message("Pi %s \n" % hostname)
        lcd.message(hostip)
        sleep(0.5)
        if (lcd.buttonPressed(lcd.UP) | lcd.buttonPressed(lcd.DOWN) | lcd.buttonPressed(lcd.LEFT) | lcd.buttonPressed(lcd.RIGHT)):
            return lcd.buttonPressed

The function does it's job until a key is pressed. Then it exits the loop but doesn't pass the button press back to the menu - I have to press it a second time and it works. Is there a simple change to the final return statement that could pass the result back? Or should I look at reengeneering the code?

You can return lcd.buttons(). That will give you a bitmap of the currently pressed buttons.
