Bahkan di situs web ebay disebutkan bahwa saya tidak dapat menggunakan layar LCD TFT 2.4 "yang terpasang pada Arduino Mega. Masalahnya adalah saya membeli perisai ini secara tidak sengaja. Saya ingin meletakkan perisai ini ke Arduino Mega 2560. Apakah ada cara untuk menggabungkan Mega dan 2.4 "Display Shield?
Catatan: Saya mencoba Arduino Uno teman saya. Shield bekerja dengan sangat baik.
Catatan: Foto di bawah ini menentukan pertanyaan saya. Layar tidak menjalankan kode Arduino saya. Ini hanya menjalankan LED-nya.
