Tarama ile 12 adet displayin sürülmesi (74HC595+ULN2803) ÇÖZÜLDÜ.

Faruk53 · 17 Nisan 2016, 21:51:49

Merhaba arkadaşlar. CCS C ile yazdığım programı XC8'e çevirmek için uğraşıyorum. Fakat bir türlü çalıştıramadım. Hiçbir türlü displaylerde herhangi birşey görünmüyor. Program 12 adet displayi sürmek için. CCS C de çalıştırmıştım herhangi bir problem yaşamamıştım. Ek olarak 32mhz pll yapmaya çalıştım. Orada mı hatam var yoksa giriş çıkış tanımlamalarımda mı ne yaptıysam olmadı. Yardımlarınız için şimdiden teşekkür ederim. İyi çalışmalar..

Arkadaşlar sorunu çözdüm. Sorun 74hc595 in yaz fonksiyonlarını tanımlarken ST_CP ucunu low konumuna çekmemem. uykusuzluk başa bela işte

Birde delay ayarlarını birazdaha kısmam gerekiyordu. kodlar aşağıdadır. belki birilerinin işine yarar. kolay gelsin.
