ESP32 - Module lvgl not found after firmware burn(lvgl 1.19.1)

Micropython
14

Hello,

Thanks for your anwser. after attempt and attempt …i built a LV_COLOR_16 Version it working without SWAP_FLAG=1
But it seem CFLAGS parameter is not taking into account … (so strange)

Now i’m attempt to display something :slight_smile: i added the drivers ST7786 made by @ kdschlosser
https://forum.lvgl.io/t/st7796s-driver-lv-micropython/4123/9
But without success. The driver start and initalize but i have a white screen.

So i decided to use the ST77xx_test.py and it is working with low level command.

My script initial script if you can give me your opinion !

import machine
import sys
sys.path.append('.')
import espidf as esp

import utime

from st7796 import *

# init display
disp = st7796(
    miso=23,
    mosi=19,
    clk=18,
    cs=5,
    dc=27,
    rst=-1,
    backlight=12,
    power=-1,
    width=480,#480
    height=320,#320
    rot=0, #PORTRAIT
)

# Create a screen with a button and a label
scr = lv.obj()
btn = lv.btn(scr)
btn.align_to(lv.scr_act(), lv.ALIGN.CENTER, 0, 0)
label = lv.label(btn)
label.set_text("Hello World!")

# Load the screen
lv.scr_load(scr)
