ESP32-4848S040C

[Bzhmic]

Hi moonnourturation and thanks for your very good work.
I'm bored with my screen because it doesn't work well with the latest version of Arduino GFX Ver 1.4.6
my screen is an ESP32-4848S040C with an ST7701. https://homeding.github.io/boards/esp32s3/panel-4848S040.htm

it works well with Arduino GFX 129 with this config

#define GFX_BL 38 // BackLight 

Arduino_ESP32RGBPanel *bus = new Arduino_ESP32RGBPanel(
    39 /* CS    */, 48 /* SCK  */, 47 /* SDA */, 18 /* DE */, 17 /* VSYNC */,
    16 /* HSYNC */, 21 /* PCLK */,
    
    11 /* R0 */, 12 /* R1 */, 13 /* R2 */, 14 /* R3 */,  0 /* R4 */, 
     8 /* G0 */, 20 /* G1 */,  3 /* G2 */, 46 /* G3 */,  9 /* G4 */, 10 /* G5 */, 
     4 /* B0 */,  5 /* B1 */,  6 /* B2 */,  7 /* B3 */, 15 /* B4 */, false );

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 */ );

but not with Arduino GFX 146 and this config

#define GFX_BL 38 // BackLight
#define ESP32_S3_RGB

Arduino_DataBus *bus = new Arduino_SWSPI(
    GFX_NOT_DEFINED /* DC */, 39 /* CS */,   48 /* SCK */, 47 /* MOSI */, GFX_NOT_DEFINED /* MISO */);

// Uncomment for 4" rect display
Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
    18 /* DE */, 17 /* VSYNC */, 16 /* HSYNC */, 21 /* PCLK */,

  /*R*/   11 /* R0 */, 12 /* R1 */, 13 /* R2 */, 14 /* R3 */,  0 /* R4 */, 
  /*G*/    8 /* G0 */, 20 /* G1 */,  3 /* G2 */, 46 /* G3 */,  9 /* G4 */, 10 /* G5 */, 
  /*B*/    4 /* B0 */,  5 /* B1 */,  6 /* B2 */,  7 /* B3 */, 15 /* B4 */, 

    1 /* hsync_polarity */, 10 /* hsync_front_porch */, 8 /* hsync_pulse_width */, 50 /* hsync_back_porch */,
    1 /* vsync_polarity */, 10 /* vsync_front_porch */, 8 /* vsync_pulse_width */, 20 /* vsync_back_porch */);
Arduino_RGB_Display *gfx = new Arduino_RGB_Display(
    480 /* width */, 480 /* height */, rgbpanel, 0 /* rotation */, true /* auto_flush */,
    bus, GFX_NOT_DEFINED /* RST */, st7701_type8_init_operations, sizeof(st7701_type8_init_operations));

part of the image at the bottom is missing

and with init1 the colors are inverted

when I have this white screen, I have to reset init 8 of v146 to have the right colors, because even with v129 the colors are inverted.

I'm using IDE 2.3.2. I have the same result with IDE 1.8.19 except for the last point where it's ok

Have a good day

why you changed type1 to type8?

[Bzhmic]

After tests, I modified the " st7701_type1_init_operations" section of the "Arduino_RGB_Display.h " file of version 1.4.6 of GFX_library_for_Arduino with the "st7701_type1_init_operations" section of the Arduino_ST7701_RGBPanel.h" file of version 1.2.9.

Version 1.4.6 works great now for my ESP32-4848S040C screen, even better, because screen rotation works.
Except for "invertDisplay" which doesn't work, which worked with ver 1.2.9.

The Guition 4848S040 work fine with the type 9 update.
Thanks for the update Moononournation ;-)
