Color problem while using ST7701 4" screen

[prof955]

ESP32-S3 + 4" ST7701 screen.
PDQgraphicstest works without problem.

When i use library to draw something like circle etc. colors are ok.
But when i try to draw Jpeg/Png/gif examples, drawing is ok but colors are not.
Not inverted colors. i tried invert, it didn't solved. See photo of screen and original image.
Problem is same for every img example like PNG, jpeg, gif bmp.

try switching between draw16bitBeRGBBitmap() and draw16bitRGBBitmap().

Unfurtunatelly didn't solved problem. Colors changed tho. but changed to another weird colors.
See below:

seem the rgb pins mapping not correct

They are exactly like the PDQexample.

#define GFX_BL 38// Back Light pini

Arduino_ESP32RGBPanel bus = new Arduino_ESP32RGBPanel(
39 / CS /, 48 / SCK /, 47 / SDA /,
18 / DE /, 17 / VSYNC /, 16 / HSYNC /, 21 / PCLK /,
4 / R0 /, 3 / R1 /, 2 / R2 /, 1 / R3 /, 0 / R4 /,
10 / G0 /, 9 / G1 /, 8 / G2 /, 7 / G3 /, 6 / G4 /, 5 / G5 /,
15 / B0 /, 14 / B1 /, 13 / B2 /, 12 / B3 /, 11 / B4 */
);
// Uncomment for 4" rect display
Arduino_ST7701_RGBPanel gfx = new Arduino_ST7701_RGBPanel(
bus, GFX_NOT_DEFINED / RST /, 0 / rotation /,
true / IPS /, 480 / width /, 480 / height /,
st7701_type1_init_operations, sizeof(st7701_type1_init_operations),
true / BGR /,
10 / hsync_front_porch /, 8 / hsync_pulse_width /, 50 / hsync_back_porch /,
10 / vsync_front_porch /, 8 / vsync_pulse_width /, 20 / vsync_back_porch */);

 This is what manufacturer info:

st7701_type1_init_operations may not match, had you tried other type number?

[prof955]

So RGB pins are ok then? i didn't try that. How can I change it? How to? Just change init like this?: st7701_type2_init_operations 17 Tem 2024 Çar 13:38 tarihinde moononournation ***@***.***> şunu yazdı:

i tried type 2 init. Screen became darker and screen is flickering BUT colors are same. So for the issue it didn't solved.
Check screenshot pls:

IDK how github works but why top left is set to "closed" while issue is not solved or something?
i really don't know :) is there no on-going, under investigation ro something like that?

I guess you are using GFX_Library_for_Arduino and not the Arduino_GFX-master library supplied with the 4.0inch_ESP32-4848S040.zip example. Or replace the library. The files Arduino_ST7701_RGBPanel.cpp and Arduino_ST7701_RGBPanel.h are different. You can change it in Arduino_ST7701_RGBPanel.h
`static const uint8_t st7701_type1_init_operations[] = {
BEGIN_WRITE,
WRITE_COMMAND_8, 0xFF,
WRITE_BYTES, 5, 0x77, 0x01, 0x00, 0x00, 0x10,

WRITE_C8_D16, 0xC0, 0x3B, 0x00,
WRITE_C8_D16, 0xC1, 0x0D, 0x02,
WRITE_C8_D16, 0xC2, 0x31, 0x05,
WRITE_C8_D8, 0xCD, 0x00,//0x08`
set Arduino_ST7701_RGBPanel *gfx = new Arduino_ST7701_RGBPanel( ........ false/*true IPS */,
and #define LV_COLOR_16_SWAP 1 in lv_conf.h
