WT32-SC01 (not PLUS) with ESP32 (not S3)

[picpic020960]

Bonjour Kevin , This vidéo for three issues : 1 - 'hello world' IS inversed 2 - the scroll IS inverted [3 - how to control the backlight] 3 - are the colors rights ? St7796 with ft6x06 (typo on CHIP_ID in ft6x06.py ?) Thanks for help (After this , return to unix port) https://github.com/user-attachments/assets/c1869a39-ac58-43c0-bb15-db4584edc13e

Édit : OK for backlight : backlight_on_state=st7796.STATE_PWM,

damned 7796 issues. This single display IC is going to be the bane of my existence.

I can fix the reversed text, that's not too big of an issue.

there are 2 possible things that can fix the touch.. The first is trying to set the startup rotation of the display.

import ft6x06

touch = ft6x06.FT6x06(
    ...
    startup_rotation=pointer_framework.lv.DISPLAY_ROTATION._180
)

If that doesn't correct the problem you can do a display calibration and that should fix it.

import ft6x06

touch = ft6x06.FT6x06(
    ...
)

if not touch.is_calibrated:
    touch.calibrate()

for the time being to correct the problem with the text being backwards... point the display at a mirror and look at the mirror... :smile:, I'm joking...

Until I am able to get around to updating the driver I am going to have you override part of the display driver...

import st7796

st7796.ST7796._ORIENTATION_TABLE = (0x40, 0xE0, 0x80, 0x20)

# create the driver as usual.

Bonjour Kevin, Calibrate and _ORIENTATION_TABLE works fine Thank's

On the video, are the colors rights ? Only this lines about colors in script :

color_space=lv.COLOR_FORMAT.RGB565,
    color_byte_order=st7796.BYTE_ORDER_BGR,
    rgb565_byte_swap=True,

And

scrn.set_style_bg_color(lv.color_hex(0x000000), 0)

[picpic020960]

Kevin , Tryed this example (lvgl v8)

https://github.com/lvgl/lvgl/blob/4d96c27ce35dd2ea6b34926f24a647e7ea7c4b0c/examples/widgets/slider/lv_example_slider_1.py

But the slider not respond You confirm ?

[kdschlosser]

you cannot use lvgl8 code it's not going to work..

[kdschlosser]

and for the display you are using you should have the color byte order set to RGB and set the rgb565 byte swap to True

Kevin , OK for the RGB for the slider example , delta in C source V8/V9 lv_obj_set_style_anim_duration(slider,2000, 0); How to write this in micropython ? edit https://github.com/lvgl/lv_binding_micropython/blob/master/examples/advanced_demo.py Lvgl V9 And all IS good ! thank's
