Pic18F4550 iç osilatörü ve config bilgileri - yardım

has_artvinli

Arkadaşlar öncelikle merhaba ben pic18f4550 nin iç osilatörünü nasıl çalıştırabileceğim hakkında biraz bilgi arıyorum örneğin bu iç osilatörü 4mhz de çalıştırmak istesem ayarları ne olacak 8mhzde ne olacak gibi konular
Bütün bunların yanında ben programı proton basic ile yaptığım için aşağıdaki gibi bir config bildirileri çıktı hepsi sağlıklı bir şekilde derlenebiliyo hatasız olarak ama ben burda bazı terimlerin anlamlarını bilmiyorum örnek vermek gerekirse FCMEM_OFF_1 gibi yada VREGEN_OFF_2,LPT1OSC_OFF_3 gibi bildiriler ne anlama geliyor yani neyi kontrol etmek için kullanılıyor bu konuda detaylı bilgiler verebilirseniz çok ama çok memnun olurum entegrenin datasheet ine baktım ama ingilizcem pek iyi olmadığı için pek de bişey çıkartamadım.

arkadaşlar şimdilik bulabildiğim konuları burada yazmak istedim bildirmem gereken şey ise konuyu farklı bir siteden başka bir arkadaşımızın anlatmış olmasıdır ki kendilerine burdan sonsuz teşekkürlerimi iletiyorum eline ve yüreğine sağlık...
tanımlamalardan ayrıca birde yine farklı sitelerden bulduğum farklı 18f serisi piclere ait proton basic ile yazılmış programları da burada örnek olması açısından paylaşmak istiyorum umarım ilgilenen arkadaşların projelerinde faydası olur...
