@russhughes - Could you confirm this?

11wanqin commented 2 years ago

my lcd is not working , when mode be equal to 0. But it is work well, when i copy the ili9XXX.py to st7789d and make the mode be equal to 2.

The following is my code:

from st7789d import st7789
import lvgl as lv
import machine

disp = st7789( miso=-1, mosi=23, clk=18, cs=26, dc=2, rst=4, backlight=5,width=240, height=240,backlight_on=0, double_buffer = False, factor=4,hybrid=False,initialize=True)

# Create a button with a label 

scr = lv.obj()
btn = lv.btn(scr)
btn.set_align(lv.ALIGN.CENTER)
label = lv.label(btn)
label.set_text('Hello world.') 
lv.scr_load(scr)

All the displays I have, use SPI_MODE 0 (clock polarity=0), but I have read that others require SPI_MODE 2 (clock polarity=1). SPI_MODE should be added to the initialization parameters.

Thank's @russhughes for this information!
I'll add a new spi_mode argument with a default value of 0.
