2,4" TFT LCD Shield an NodeMCU ESP 8266 Verdrahtung und Library

Hallo Gemeinde,

ich bin auf der Suche nach einem Verdrahtungsplan und entsprechendem Library für o.g. Komponenten. Möglich wäre auch ein 1,8" TFT Modul SPI 128x160.
Für Hilfe wäre ich außerordentlich dankbar :-)

Gruß, Atze

Moin Atze68,

Willkommen im Forum,

hast du vllt ein paar Links zu deiner geplanten Hardware ? Es gibt via Google schon viele Howtos dazu.

Servus,

dass 1,8" habe ich jetzt zum Laufen gebracht, allerdings klappt es mit dem 2,4" TFT LCD Shield noch nicht.
Hardware: ESP 8266 Nodemcu Lolin und 2,4" TFT LCD Shield Display.
Treiber für das Display ist der ili 9341.

Gruß, Atze

welche ILI9341 Treiber Lib verwendest du?

und verlinke bitte mal dein TFT Shield!

Dieses ist mein Display:

Ich würde die Beispiel ILI9341 anpassen und dann verwenden, allerdings müsste erstmal die richtige Verdrahtung erfolgen.....

der Link zu Adafruit_ILI9341 Lib und Adafruit ILI9341 Shield http://www.adafruit.com/products/1651 hätte gereicht, der Beispielcode ist nicht so wichtig (bitte Code aber auch immer in code-tags formatiert posten!).

Aus meiner Erfahrung könnte es sich als Problem herausstellen, falls adafruit Software-SPI verwendet, aber ob das so ist, kann ich nicht sagen.
Dieses Adafruit Shield kenne ich aber auch nicht, daher muss dir dann doch jemand anderes helfen.

Soooo,

jetzt habe ich bei Amazon das richtige Display gefunden: https://www.amazon.de/Yongse%C2%AE-t.../dp/B01I1PR580
Genau dieses habe ich. Ob es sich an einen NodeMcu Lolin ESP 8266 anknüppeln lässt ?
