Description
Dear All:
the system cannot find the following lib. Could someone give me a hint?
import pytest
| from baseline_data import get_reference_data, primitives
| from helpers import Mock, serial, call, setup_function, assert_invalid_dimensions # noqa: F401
The ST7567 1.8 LCD is not lighted up even I wired it as exactly what the document said.
How to turn on the backlight?
It mentioned that GPIO18 can be used for backlight how to wire and code that?
Thanks a lot.

can you share the code you're using?

Thanks for your feedback. All the codes are from the the examples here. There is nothing new.
I bought 3 OPEN-SMART 1.8INCH LCD ST7567. None of them has any response.
So my first question now is how to light up to check whether it works?
The GPIO setup
Board - GPIO Pin# (GPIO name)
GND - 09
3V3 - 01
SDI - 19 (GPIO10 SPI0-MOSI)
SCK - 23(GPIO11 SP10_CLK)
DC - 16(GPIO23)
CS - 24(GPIO08, SPI0-CE0_N)
RST - 18(GPIO24)
Could you please help me to check whether the wiring is right?
