lcd menu buton algılama sorunu

[matter]

Merhaba,stm32f103'de 16x02 lcd menu kullanarak sera otomasyonu yapıyorum.Mikrodenetleyici programlamada yeniyim.Ana ekranda saat,tarih,sıcaklık gibi bilgiler bulunuyor.Set butonuna bastığım zaman menu kısmına giriyor.

Benim sorunum menu kısmına geçince menuler arası geçiş yaparken butona basınca bazen algılıyor bazen butonu kaçırıyor.Geçişleri düzgün olarak yapabilmem için butona 1 sn gibi basılı tutmam gerekiyor.Fakat benim istediğim butona bastımmı hiç kaçırmaması.Nerede hata yapıyorum,yardımcı olur musunuz?Teşekkürler...[code]
