Arkadaşlar merhaba,
Proteusta her zaman hoşuma giden ve basic ile kod yazarken severek kullandığım seri LCD nin c kodlarını 18F4520 işlemci kullanarak xc8 de derledim.Kısaca bilgi vermek isterim.seri LCD tek portla çalışır, bu port istediğiniz bir işlemcinin herhangi bir portu olabilir.
Proteusta simulasyonu nu yaparken seri LCD yi üzerine tıklayarak hız ayarını yapınız(9600/2400 baud).
Yine seri lcd yi hangi hıza ayarladınız ise program içinde -->baud_kur(baud)<<-- programında hızı 9600/2400 olarak giriniz.
Tüm ayarlar bu kadar.
