http://speedy.sh/HHXYA/Usart.rar proje dosyasını buraya kopyaladım.Nerede hata yaptığımı anlamadım.Daha doğrusu v1.3 kütüphaneyi neden kullanamıyorum?

[sseedat]

ben sorunsuz belirttiğiniz kütüphane versiyonunu kullanıyorum sıkıntı çıkmadı.
dma ile ilgili dosyaları projeye dahil ettiniz mi. .

[pisayisi]

Kütüphane dosyaların düzgün yapılandırılmamış gibi görünüyor , aşağıda derlenmiş şablon projeyi dene senin main.c yi ekledim sorunsuz derleniyor...

http://speedy.sh/ccnnT/stm32f4-proje-sablon-uart.rar

Teşekkürler. Çalışıyor.Sen verdiğin şablon ile istediğim şekilde daha düzenli proje dosyası oluşturup template gibi kullanıyorum.Ancak benim verdiğimde ne gibi düzensizlik vardı?Yani neden derleme hatası alıyordum?

[Mucit23]

Teşekkürler. Çalışıyor.Sen verdiğin şablon ile istediğim şekilde daha düzenli proje dosyası oluşturup template gibi kullanıyorum.Ancak benim verdiğimde ne gibi düzensizlik vardı?Yani neden derleme hatası alıyordum?

Mutlaka bir yerde eksik birşeyler yapıyorsundur. Bence indirdiğin template projeye bakarak kendin yeni bir proje oluşturmaya çalış. Zamanında ben öyle yapa yapa öğrenmiştim.

Aslında STD_Peripheral_Library kullanılarak sıfırdan proje kurulumuna dair forumda hiçbir anlatım yok. Bu bence bir eksiklik

[yldzelektronik]

Mutlaka bir yerde eksik birşeyler yapıyorsundur....

Orası kesin de nerede ne hata yaptığımı bılmaya çalışıyorum. Ki aynı hataları tekrarlamayayım.

Bu arada dma kullanımından bahsedebilir misiniz?

Adc ile dma kullanarak 10 elemanlı diziye veriyi yazıp, veriyi 30 elemanlı bir stringe çevirmek ve yine dma ile usart üzerinden göndermek istiyorum.

Normalde adcden veriyi okuyup diziye yazdıktan sonra kesme oluşturuyorum.O kesmede median filtreden geçirip usart dmayı açmak ve adc dma yı kapamak istiyorum.Usart dma veriyi yolladıktan sonra kendini kapatıp adc dmayı açsın istiyorum.

Adc dma ile veriyi 10 elemanlı diziye yazıyorum.Ama usart çalışmıyor.

Bir de incelediğim örnek programda gariplik olduğunu düşünmeye başladım.Adc 12bit.Değişken 32 bit.Okuduğum değerler ilginç değerler. Bir türlü doğru gerilimi hesaplayamadım.
