STM32F429 EXTI Problem

[Forever_Embedded]

Merhaba;

PG9 ve PA9 pinlerine birer buton bağladım. Bunların ikisinin de pin sourceları aynı olduğu için hangisini main dosyasının içinde sonradan yazsam sonradan yazdığım buton çalışıyor sadece. Bunu it.c dosyasındaki fonksiyona aşağıdaki kodu yazarak aşmaya çalıştım ama olmadı:

if(EXTI_GetITStatus(LCD_B1_PINLINE) == SET && GPIO_ReadInputDataBit(LCD_B1_PORT,LCD_B1_PIN)==1 )
{
...
}

Aşağıda Configurationn ayarlarını veriyorum:

#define LCD_B5_PIN  GPIO_Pin_9

/*LCD Button Pin Sources,Lines, Port Sources for EXTI*/

Gerçekten zor bir soru sormuşum kimseden cevap gelmedi

[magnetron]

exti9-5 interrupt bütün portlar için sadece 1 tane var

aşağıdaki resim ( reference manual'den )

yani 2 değişik porta ayrı ayrı exti9_5 tanımlayamazsınız
