In the hd44780 library, how do you use the set_backlight function? The first argument is 'hd44780_t *lcd' whereas the other functions use 'const hd44780_t *lcd' which is &lcd in my code (following the example provided) so I'm wondering what I need to write in set_backlight to get it to work. Context: Trying to turn the backlight on and off with a button.
