ESP32-S3 7-inch Display: How to Rotate Text from Horizontal to Vertical?

[raylan22]

Hello everyone, I'm new here

I recently purchased a 7-inch display with an ESP32-8048S070 chip.

Link: https://aliexpress.com/item/1005004952726089.html?spm=a2g0o.order_list.order_list_main.23.2c585c5fCZLXQj&gatewayAdapt=glo2deu

With the example code, I can display text, but unfortunately, it's always displayed horizontally, and I'd like to have it displayed vertically.

Here's what I've tried so far:

gfx->setRotation(1);

However, this doesn't seem to work. I suspect it might be due to the RGB panel.

Here's the code I'm using:

#include <Arduino_GFX_Library.h>
#define GFX_BL DF_GFX_BL
#define TFT_BL 2

#if defined(DISPLAY_DEV_KIT)
Arduino_GFX *gfx = create_default_Arduino_GFX();
#else
Arduino_ESP32RGBPanel *bus = new Arduino_ESP32RGBPanel(
  GFX_NOT_DEFINED, GFX_NOT_DEFINED, GFX_NOT_DEFINED,
  41, 40, 39, 42,
  14, 21, 47, 48, 45,
  9, 46, 3, 8, 16, 1,
  15, 7, 6, 5, 4);
Arduino_RPi_DPI_RGBPanel *gfx = new Arduino_RPi_DPI_RGBPanel(
  bus,
  800, 0, 210, 30, 16,
  480, 0, 22, 13, 10,
  1, 16000000, true);
#endif
#define BACKGROUND BLACK
#define TEXT_COLOR WHITE

void setup(void) {
  Serial.begin(9600);
  gfx->begin();
  gfx->fillScreen(BACKGROUND);

#ifdef TFT_BL
  pinMode(TFT_BL, OUTPUT);
  digitalWrite(TFT_BL, HIGH);
#endif
}

void loop() {
  gfx->setTextColor(TEXT_COLOR);
  gfx->setTextSize(2);
  gfx->setCursor(2, 2);
  gfx->println("hello world");
  delay(100);
  gfx->fillScreen(BACKGROUND);
  Serial.println("hello world");
}

Does anyone have any suggestions? Thanks in advance and have a great Sunday!

Best regards,
Raylan

this is what the display looks like.

I would like to have the text on the top left.

@raylan22

gfx->setRotation(1);

did you try other values..
try 0, think that's the one you need..
do in setup, just below screen begin..

good luck.. ~q

[raylan22]

with:

  gfx->begin();
  gfx->setRotation(0);

the output looks the same.

with:

  gfx->begin();
  gfx->setRotation(1);

does it look like it?

looks like the rgb channels does not support the function?

Hi, I have the same problem, did you find a solution? Thanks.

[qubits-us]

No, it was a limitation of the hardware i believe..
sorry.. ~q

[guimbastos]

did you manage to rotate the screen? If yes, what was the procedure? Thanks.
