Hello! How can I rotate the screen? I need to set portrait orientation.
I use display with driver ILI9488.

As I understand it, I need to change the starting coordinates of the rendering in the file ili9488.c :

`/* Column addresses */
uint8_t xb[] = {
(uint8_t) (area->x1 >> 8) & 0xFF,
(uint8_t) (area->x1) & 0xFF,
(uint8_t) (area->x2 >> 8) & 0xFF,
(uint8_t) (area->x2) & 0xFF,
};

/* Page addresses  */
uint8_t yb[] = {
    (uint8_t) (area->y1 >> 8) & 0xFF,
    (uint8_t) (area->y1) & 0xFF,
    (uint8_t) (area->y2 >> 8) & 0xFF,
    (uint8_t) (area->y2) & 0xFF,
};`

I made corrections to the void ili9488_init (void) function in the ili9488.с file, {ILI9488_CMD_MEMORY_ACCESS_CONTROL, {(0x20 | 0x08)}, 1}
I changed it to
{ILI9488_CMD_MEMORY_ACCESS_CONTROL, {0x48}, 1},

I think you can add this option to menuconfig

Hi @Djaison,

Can you try swapping the values on this config?

If that doesn't work i can add an option to the menuconfig as you've suggested.

Offtopic: Your interface looks really cool :)

it does not work :)

now it looks like this

Ok, I will try to add an option to set the display on portrait mode from the menuconfig, but it will be later today.

It would be good to add this option for the ILI9341, too. I just worked on this today and found that for the M5Stack Fire in the file externals\lv_port_esp32\components\lvgl_esp32_drivers\lvgl_tft\ili9341.c writing 0x08 (instead of 0x68) to 0x36 worked for me. With this the display shows in landscape, with the buttons on the bottom. I used this code:

#if ILI9341_INVERT_DISPLAY
uint8_t data[] = {0x08};
// this same command also sets rotation (portrait/landscape) and inverts colors.
// https://gist.github.com/motters/38a26a66020f674b6389063932048e4c#file-ili9844_defines-h-L24
ili9341_send_cmd(0x36);
ili9341_send_data(&data, 1);
#endif

Value taken from ILI9341 datasheet, section 8.2.29. Memory Access Control (36h). Also height and width must be swapped, too. I did it like this in file externals\lv_port_esp32\components\lvgl\lv_conf.h

#define LV_HOR_RES_MAX (CONFIG_LVGL_DISPLAY_HEIGHT)
#define LV_VER_RES_MAX (CONFIG_LVGL_DISPLAY_WIDTH)

Sure, I will add it later today, I'm at work right now.

I was able to configure the touch to the portrait orientation should also change the default settings in menuconfig, the operating settings such:

Result ;-)

P.S. Touch driver is a FT6236

It looks really nice :)

We can add a note for that on the README, I don't know if it can be done automagically based on the display orientation.

[Djaison]

it can be added to menuсonfig as a function of the orientation of the display, and later I will be able to provide it after checking
