control of colors) and the hardware supports PWM on the provided pins,
set enable_pwm to True. Finally you can set an explicit initial backlight
color with the initial_color parameter. The default initial color is

the number of columns and lines on the LCD.
The red, green, and blue parameters define the pins which are connected
to the appropriate backlight LEDs. The invert_polarity parameter is a
boolean that controls if the LEDs are on with a LOW or HIGH signal. By
default invert_polarity is True, i.e. the backlight LEDs are on with a
low signal. If you want to enable PWM on the backlight LEDs (for finer
control of colors) and the hardware supports PWM on the provided pins,
set enable_pwm to True. Finally you can set an explicit initial backlight
color with the initial_color parameter. The default initial color is
white (all LEDs lit).
You can optionally pass in an explicit GPIO class,
for example if you want to use an MCP230xx GPIO extender. If you don't
pass in an GPIO instance, the default GPIO for the running platform will
be used.

You can enable PWM of the backlight pin to have finer control on the

you can provide an explicit one with the pwm parameter.

explicit initial state with the initial_backlight parameter (0 is off,

You can optionally pass in an explicit GPIO class,
