STM32F7 Discovery GPIO setlenmiyor

[unknownperson]

STM32F7 Discovery kullanıyorum, çok saçma bir durumla karşı karşıyayım.
STM32CUBEMx 'de GPIO bacağını PI2(MCU pin'i olarak) yani D8(kit üzerinde) belirliyorum.(PI2 sağ tıklayıp Output olarak seçiyorum.)
HAL_GPIO_WritePin() fonksiyonu ile setlemek istiyorum fakat programı load edince kitte o pinde 5V okumayı beklerken 0V okuyorum.
Koddaki main.c şöyle:

__HAL_RCC_GPIOB_CLK_ENABLE(); // bu satırda gpiob nin clockunu aktif ediyor. oysaki siz I nin pinini kullanıyorsunuz[/size]

[unknownperson]

Hocam ufak denemeler yapmıştım ondan kodu buraya yapıştırırken değiştirmeyi unutmuşum, şimdi kodu tekrar üretip iletimi düzenledim tekrar bi bakabilir misiniz bu şekilde çalıştırdım gene 0V gördüm.

[skara1214]

hocam debug yapamadan göremessin bence yüksek ihtimal bir yerde hard faulta düşüyordur.zira bende dma yı hal libraryinin kodlarıyla kullanmaya kalkınca hard faulta düştüğünü gördüm. Sonra kendim düzenledim sıknıtı kalmadı.
Sizdede böyle bir sıkıntı varsa sizde registerler üzerinden ayarlama yapabilirsiniz.

[unknownperson]

Hocam o zaman şöyle diyeyim şimdi bu Cubemx dediğimiz program bizim init ve config işlerimizi main.c içinde tanımlıyor bir de kütüphaneleri gönderiyor. Ben bu projede LCD, GPIO ve DAC kullanıyorum. Ben LCD işini STemWin example'ı ile hallettim. Bu example üzerinden Keil'da Manage Run time environment'ı açarak gerekli şeyleri seçsem. Sonrasında init ve config işlemlerini el ile main.c içine yazsam olur mu ? 

[skara1214]

olur tabi ama neden debug yapmayı reddediyorsunuz onu anlamadım

[unknownperson]

Aslında şu yüzden elimde çalışan cubemx ile oluşturulmamış bir yazılım var,
Öte yandan cubemx ile olusturduğum gpio, dac yazılımı var ama doğru çalışmıyor.
Amacım çalışan yazılımı bozmadan yazılımları birleştirme.


Öte yandan hard fault ile ilgili bilgim yok. Sanırım breakpoint koyup debugda adım adım yazılım bir yerde takılıyor mu diyee bakıcam writepin'e geliyor mu diye kontrol edicem .

[muhittin_kaplan]

projeyi biryere atarsan (CubeMx) deneyebilirim.

[unknownperson]

Hocam sanırım sadece GPIO olan projeyi atmamı istediniz, buyrun :

http://www.dosyaupload.com/1Foz

Bu arada stm32f7 discovery pinlerini çok saçma yapmışlar, belki yanlış pine bakıyorumdur o yüzden tekrar bi tüm pinleri ölçeyim.

[unknownperson]

Hocam sorunu çözdüm, sıkıntı şuymuş flash download kısmında reset and run seçili değilmiş butona basınca tekrar ölçüm yaptım o şekilde anladım.

[skara1214]

bende o hatayı çok yapıyorum alışıyor insan

[unknownperson]

Ben aslında düzeltmiştim de yeni proje açınca sıfırlanıyormuş ben keil otomatik tutuyor sandım, neyse tecrübe oldu bu da ilk oraya bakıcam artık 


O bitti şu başladı hocam basit bir DAC oluşturmak istedim sadece 2V civarı bir değer görsem yeterli sonrasında kendim bir fonksiyon yazıcam göndermek istediğim değer için.


Hesabı şu şekilde verilmiş :



*** DAC data value to voltage correspondence *** 
       ================================================
       [..]
       The analog output voltage on each DAC channel pin is determined
       by the following equation:
       DAC_OUTx = VREF+ * DOR / 4095
       with  DOR is the Data Output Register
          VEF+ is the input voltage reference (refer to the device datasheet)
        e.g. To set DAC_OUT1 to 0.7V, use
          Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
 


Şuan aşağıdaki kodu yazdım 0V görüyorum :
