STM32 F4xx and ST7789 240x320 bug

[Satanpit]

Hello. I have a problem with STM32 F4xx and ST7789 240x320. If i define STM32 i have screen resolution only 240x240

My display - Wiki

Code example:

#include <Arduino.h>
#include <Wire.h>

#include <TFT_eSPI.h>
#include <SPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.begin();
  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_RED);

  tft.setCursor(0, 26);
  tft.setFreeFont(&FreeSans18pt7b);
  tft.setTextColor(WHITE, BLACK);
  tft.print("Test text");
}

void loop() {}

User setup code:

#define STM32

#define ST7789_DRIVER      // Full configuration option, define additional parameters below for this display

#define TFT_RGB_ORDER TFT_BGR  // Colour order Blue-Green-Red

#define TFT_WIDTH  320 // ST7789 240 x 240 and 240 x 320
#define TFT_HEIGHT 240 // ST7789 240 x 320

#define TFT_BL   PC14            // LED back-light control pin
#define TFT_BACKLIGHT_ON HIGH  // Level to turn ON back-light (HIGH or LOW)

#define TFT_MISO PA6
#define TFT_MOSI PA7
#define TFT_SCLK PA5
#define TFT_CS    PB6
#define TFT_DC    PA8
#define TFT_RST   PA9

#define LOAD_GLCD   // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2  // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters
#define LOAD_FONT4  // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6  // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm
#define LOAD_FONT7  // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:-.
#define LOAD_FONT8  // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.
//#define LOAD_FONT8N // Font 8. Alternative to Font 8 above, slightly narrower, so 3 digits fit a 160 pixel TFT
#define LOAD_GFXFF  // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

#define SMOOTH_FONT

// #define SPI_FREQUENCY  80000000

// Optional reduced SPI frequency for reading TFT
#define SPI_READ_FREQUENCY  20000000

// The XPT2046 requires a lower SPI clock rate of 2.5MHz so we define that here:
#define SPI_TOUCH_FREQUENCY  2500000

Result screen:

The screen size must be specified in portrait orientation. So use:

#define TFT_WIDTH  240
#define TFT_HEIGHT 320

See example setup.

@Bodmer i try to use your example, but have the same problem

Sorry to break in this closed thread, but i have the same situation. My user_setup.h has width and hight mixed up (landscape mode) but it works with all my 15 tft screens correctly (w = 128, h=160 ST7735), only the sprite(screen) buildup is in protrait. Maby these issues are related. I cannot find where to set the sprite(screen) to portrait.
