Need help with T-Watch 2020 V1 TFT_ESPI PLATFORM IO

[2ant]

Hi, i desperately need help, I'm trying to use the last version of tft_espi library with my watch.

I'm using Platform IO, I installed the ttgo library but the version of tft_espi in it is too old si I installed it separately but I'm having trouble finding how to make it work.

After a while i found this :

#if !defined(EXTERNAL_TFT_ESPI_LIBRARY)
    #if defined(LILYGO_WATCH_HAS_DISPLAY) || defined(LILYGO_EINK_TOUCHSCREEN) || defined(LILYGO_WATCH_HAS_EINK)
        #include "libraries/TFT_eSPI/TFT_eSPI.h"
        #include "libraries/U8g2_for_Adafruit_GFX/src/U8g2_for_Adafruit_GFX.h"
    #endif
    #else // EXTERNAL_TFT_ESPI_LIBRARY
        #include <TFT_eSPI.h>
#endif /*EXTERNAL_TFT_ESPI_LIBRARY*/

I added the flag in my config.h file :

#define LILYGO_WATCH_2020_V1              // Use T-Watch2020

#define LILYGO_WATCH_LVGL

#define EXTERNAL_TFT_ESPI_LIBRARY

#include <LilyGoWatch.h>

#include "icones.h" 

#include "esp_sleep.h"

I chose the right user setup in the newer tft_espi library and then tested a simple code that works :

#include <Arduino.h>

#include "config.h"     

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

TFT_eSPI tft = TFT_eSPI();
TFT_eSprite spr(&tft), spr1(&tft);

TTGOClass *ttgo; 

void setup() 
{

  Serial.begin(115200);

  Serial.println("start");

  ttgo = TTGOClass::getWatch();
  ttgo->begin();     
  ttgo->openBL();
  ttgo->bl->adjust(255);

  tft.init();

  tft.setRotation(2);

  tft.fillScreen(TFT_BLUE);

}

void loop()
{

}

I then tried a simple code to test screen + touch :

#include <Arduino.h>

#include "config.h"     

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

TFT_eSPI tft = TFT_eSPI();
TFT_eSprite spr(&tft), spr1(&tft);

TTGOClass *ttgo; 

char buf[128];

void setup() {

  Serial.begin(115200);

  Serial.println("start");

  ttgo = TTGOClass::getWatch();
  ttgo->begin();     
  ttgo->openBL();
  ttgo->bl->adjust(255);

  tft.init();

  tft.setRotation(2);

  tft.fillScreen(TFT_RED);

  tft.setTextFont(2);
  tft.setTextColor(TFT_WHITE, TFT_BLACK);
  tft.drawString("T-Watch Touch Test", 62, 90);

}

void loop()
{
  int16_t x, y;
    if (ttgo->getTouch(x, y)) {
        tft.drawString("Touch detected", 62, 90);
        sprintf(buf, "x:%03d  y:%03d", x, y);
        tft.drawString(buf, 80, 118);
    }
    delay(5);

}

I get a red screen with text but when I touch it the watch reboots.

I get this in my VS Code terminal :
