Support ST7701s IPS TFT 5 inch 854x480 RGB+SPI With ESP32-S3 about lovyangfx HOT 15 OPEN

hi,

given the square-ish shape it looks like cfg.offset_rotation = 1 (or another value up to 3) is needed for the panel config

hscync/vsync values seem to need adjustment too, but first fix the rotation

from lovyangfx.

Thank you for your advice, but setting cfg.offset_rotation from 0-3 still doesn't work.

...
cfg.offset_x = 0;
cfg.offset_y = 0;
cfg.offset_rotation = 0; // <- I've tried entering values ​​from 0-3, but still doesn't work!

If you need information about this display and other information, It's already on top.

What should I do next?

from lovyangfx.

but still doesn't work!

this is an issue tracker, not a customer service, the quality of the support you get is as good as the feedback you give

from lovyangfx.

Here is a picture of the results I got.

cfg.offset_rotation = 0

cfg.offset_rotation = 1

cfg.offset_rotation = 2

cfg.offset_rotation = 3

from lovyangfx.

thanks,

offset rotation 1 and 3 don't show the cropped square, so there's progress, I suggest you keep cfg.offset_rotation=1 for the meantime

I don't read Chinese and can't make much of the datasheet but it also looks like hsync*/vsync* values need to be adjusted with values provided by the vendor:

            cfg.hsync_front_porch = 20;//10;
            cfg.hsync_pulse_width = 1;//8;
            cfg.hsync_back_porch  = 42;//50;
            
            cfg.vsync_front_porch = 4;//10;
            cfg.vsync_pulse_width = 10;//8;
            cfg.vsync_back_porch  = 12;//20;

unfortunately the google drive zip file is invalid and/or infected and I can't compare your values with the recommended settings

error: invalid zip file with overlapped components (possible zip bomb)
 To unzip the file anyway, rerun the command with UNZIP_DISABLE_ZIPBOMB_DETECTION=TRUE environmnent variable

• did you manage to unzip the zip archive?
• does the sample code work with your display?

if the answer is yes to both questions please share the code of that sample ( try https://gist.new ) so we can compare the configurations

I edited the file (on the original link) so I expect you should be able to open it normally.

did you manage to unzip the zip archive?

Yes, I unzip the zip archive and I have access to all the files normally.

does the sample code work with your display?

I have not yet tried out the code I received. Because the example the seller sent me has the project format used in ESP-IDF (the seller said there is no example code for Arduino IDE) and now I am developing my project on Arduino IDE(ArduinoESP32 V2 .0.17) only

from lovyangfx.

esp-idf calls this variant LCD_5r0_480x854, so you can try to invert the height/width values

        cfg.memory_width  = 480
        cfg.memory_height = 854;
        cfg.panel_width  = 480;
        cfg.panel_height = 854;

you may have to adjust cfg.offset_rotation again during your tests though

The results look much better than before! And this is an illustration.

cfg.offset_rotation = 0

cfg.offset_rotation = 1

cfg.offset_rotation = 2

cfg.offset_rotation = 3

from lovyangfx.

could it be that pin_vsync and pin_hsync need to inverted too?

            cfg.pin_vsync   = 17;
            cfg.pin_hsync   = 47;

from lovyangfx.

could it be that pin_vsync and pin_hsync need to inverted too?

I tested it and the result was that nothing was displayed on the screen and everything was black.

Could the incorrect display of the display be related to the ST7701s init command?
I noticed that this display has SPI+RGB communication.

from lovyangfx.

init commands sequences are hardcoded for this panel, but there is another variant of Panel_ST7701 that you may want to try: Panel_ST7701_guition_esp32_4848S040

from lovyangfx.

that you may want to try: Panel_ST7701_guition_esp32_4848S040

This is the result

from lovyangfx.

colors can be adjusted with cfg.invert and cfg.rgb_order (both booleans) options

that deinterlacing effect is similar to what you had with the Panel_ST7701 with cfg.offset_rotation = 2 so the init sequence is probably not the cause and I'm out of ideas
