I have a 1.3" SPI Colour Square LCD (240x240) Breakout which I want to use with a Pi Pico W and micropython.
However the default pins are not available.
These are the defaults
- 3-5V to any 5V or 3V pin
- CS to GP17
- SCK to GP18
- MOSI to GP19
- DC to GP16
- BL to GP20
- GND to any ground pin
I know how to change the SPI pins but not how to change the backlight pin
changing the SPI pins: (default values for illustration)
from pimoroni_bus import SPIBus
from picographics import PicoGraphics, DISPLAY_LCD_240X240, PEN_P8
spibus = SPIBus(cs=17, dc=16, sck=18, mosi=19)
display = PicoGraphics(display=DISPLAY_LCD_240X240,, bus=spibus, pen_type=PEN_P8)
I want to make use of the display.set_backlight(0.5) command but I need to specify a pin other than GP20
can someone point me to where I can change the default backlight pin please?
