STM32F4 Discovery Dokunmatik Ekrana Resim Çizme Uygulaması

Merhaba arkadaşlar yeni ve özgün bir uygulamayla tekrar karşınızdayız.Bu yazımızda bizden çok kodlar konuşacağı için çok fazla açıklama  yapmak istemiyorum.Aşağıda paylaşacağım kodları derleyerek daha güzel projeler elde edeceğinizi düşünüyoruz.Bu uygulama temel olarak dokunmatik ekrana resim nasıl çizilirden çok daha fazla bilgi içermektedir.Tabi ki bunun için kodları dikkatle incelemenizi tavsiye ediyorum.Özellikle yazı nasıl yazdırılır,buton nasıl çizdirilir vb. detayları göreceğinizi umuyorum.
