I would like to thank to Mr.Masayuki Tanaka who is the owner of https://lang-ship.com/blog/
He gave us an important suggestion about how to get screenshots of this LCD.

<Important Tips>
To capture and save the LCD screen, the above R24 should be soldered!!

2.Software

Software: Arduino IDE + libraries
ESP32 and DPS310 libraries

Some essence for ArduinoIDE driving software

void setup() {

Serial.begin(9600);   // at first!
wifi_start();            // wifi

// Initialize SD card.      forget this! 2023-01-24
    if (!SD.begin()) {
        lcd.println(
            "Card failed, or not present"); // Print a message if the SD card
        while (1);
    }

lcd.init();
// 回転方向を 0～3 の4方向から設定します。(4～7を使用すると上下反転になります。)
lcd.setRotation(3);

Serial.begin(115200);

lcd.setColorDepth(16);
lcd.startWrite();
lcd.setAddrWindow(0, 0, lcd.width(), lcd.height());

while (!Serial);      // confirmatiion
Dps310PressureSensor.begin(Wire);     // connect to DPS310 via i2c
Serial.println("Init complete!");     // serial port completed
//WiFi.mode(WIFI_OFF);         // 2022-08-15 https://www.mgo-tec.com/blog-entry-m5stack-yahoo-weather-news-scrolle-watch-message.html
