ben PIC16F877 ENTEGRESİ VE PCF8583(SAAT VE TARİH İÇİN ENTEGRE),LM35 ISI SENSÖRÜ İE TARİH SAAT VE SICAKLIĞI
Lcd EKRANDA GÖSTERMEK İSTİYORUM..
BUNUNLA İLGİLİ BİR PROGRAMA SAHİBİM AMA BENİM PROGRAMIMDA SICAKLIĞI GAYET İYİ GÖSTERİYOR SICAKLIKTA SORUN YOK.. AMA TARİH VE SAAT SABİT BİR ŞEKİLDE KALIYOR İLERLEMİYOR
MESELA SAAAT 12:10:09 BİR TÜRLÜ 12:10:10 OLMUYOR SABİT KALIYOR BEN MİCROC PRO FOR PİC PROGRAMIYLA YAZILMIŞ BİR PROGRAM...
PROTEUSDA SİMULASYON YAPTIĞIM ZAMAN DEVAMLI SAAT KONUSUNDA SORUN YAŞIYORUM...BEN DEVREMDE KULLANDIĞIM MALZEMELERİ,PROTEUSDA ÇİZİLMİŞ DEVREMİ VE PROGRAMIMI
ATACAĞIM YARDIMCI OLURSANZ ÇOK SEVİNİRİM...BUNU YAPAMAZSAM DERSTEN KALACAĞIM
KULLANDIĞIM MALZEMELE: Materials: RS232 İLETİŞİM KABLOSU,PIC16F877 ENTEGRESİ,LCD 2*16
