STM32F103 SPI2 Problemi

[baran123]

Hayırlı akşamlar,
Saatlerdir uğraşıyorum fakat STM32F103C8T6 için SPI2 çalıştıramadım.
Pini çıkış yapıp led falanda yaktım sorun ama SPI bir türlü veri basmıyor.
Osilaskop ve Logic analyzer ile canlı izliyorum fakat hiç bir değişiklik yok.
Hat sürekli olarak Logic 1 de kalıyor(SCK ve MOSI)
İnternetteki örnekleride denedim ama nafile.
Kodlar aşağıda konfigurasyonu incelerseniz sevinirim.

Sorunu yakaladım fakat çözemedim.
TIM1 kullanarak PWM çıkartıyorum Bu PWM'ler A8,A9,A10,A11 den çıkıyor. Bunların Complement kanalları aktif değil.

Neden sorun çıkardığını anlamadım.
TIM1 ayarlarım şu şekilde
