The LCD will be used in its 4-bit mode so these 6 lines are the only ones
required to use the LCD. You must also pass in the number of columns and

If you would like to control the backlight, pass in the pin connected to
the backlight with the backlight parameter. The invert_polarity boolean
controls if the backlight is one with a LOW signal or HIGH signal. The
default invert_polarity value is True, i.e. the backlight is on with a
LOW signal.
You can enable PWM of the backlight pin to have finer control on the
brightness. To enable PWM make sure your hardware supports PWM on the
provided backlight pin and set enable_pwm to True (the default is False).
The appropriate PWM library will be used depending on the platform, but
you can provide an explicit one with the pwm parameter.
The initial state of the backlight is ON, but you can set it to an
explicit initial state with the initial_backlight parameter (0 is off,
1 is on/full bright).
You can optionally pass in an explicit GPIO class,
for example if you want to use an MCP230xx GPIO extender. If you don't
