Hi HotSystems,
Das Display ist einfach ein Shield und somit einfach auf das Arduino Uno WiFi ähnliche Board gesteckt. Die "Verkabelung" sieht folgendermaßen aus.
Hier nochmal mein Code direkt im Forum:
/***********************************************************************************
*This program is a demo of clearing screen to display red,green,blue.
*This demo was made for LCD modules with 8bit or 16bit data port.
*This program don't need to rely on any libraries and Can run directly.
* File : _9486uno.ino
* Hardware Environment: Arduino UNO
* Build Environment : Arduino
*Set the pins to the correct ones for your development shield or breakout board.
*This demo use the BREAKOUT BOARD only and use these 8bit data lines to the LCD,
*pin usage as follow:
* LCD_CS LCD_CD LCD_WR LCD_RD LCD_RST SD_SS SD_DI SD_DO SD_SCK
* Arduino Uno A3 A2 A1 A0 A4 10 11 12 13
* LCD_D0 LCD_D1 LCD_D2 LCD_D3 LCD_D4 LCD_D5 LCD_D6 LCD_D7
* Arduino Uno 8 9 2 3 4 5 6 7
*Remember to set the pins to suit your display module!

Die aktuelle Library an der ich mich versuche ist folgende: GitHub - Bodmer/TFT_eSPI: Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips
Vielen Dank für die Antwort!
