Arduino ile Dokunmatik TFT Ekran Kullanımı:Ekrana Yazı Yazdırma

Merhaba arkadaşlar bu yazımızda sizlerle Arduino ile dokunmatik TFT ekrana yazı yazdırmayı göreceğiz.Bu uygulamada SSD1289 LCD ekran sürücüsüne sahip 320×240 pixel ve 65K-16 bit renk çözünürlüğüne sahip TFT ekranı kullanacağız.Uygulamada programlama kartı olarak Arduino Mega’yı kullanacağız.Aşağıda kullanacağımız ekranın ön ve arka yüzü gösterilmiştir.

Kullanılan Malzemeler

• Arduino Mega
• TFT Ekran
• Jumper Kablolar

Dokunmatik ekranın pinleri aşağıda verilmiştir.

Tft ekran ve Arduino MEGA bağlantı pinleri aşağıda verilmiştir.

Programı yazmaya başlamadan önce UTFT kütüphanesini indirmemiz gerekmektedir.Aşağıda linki verilmiştir.

Kütüphanemizi indirdikten sonra uygulamamıza başlayabiliriz.
