Stm32f051 disc ile bir test yaptım, hatta yazisinida yazmistim.
Ama bir hata var sanirim.
Tim17 yi oneShot olarak init ettim. Channel1 i pa7 ye verdim. Ve pwm çıkış yap dedim.
Ama nedense pa7 yi init de alternate olarak görmüyorum.
Neden ?

Tımarların her bir kanalı icin
Compare,pwm,force output mevcut nedir bunlar?

Kod da neden PA7 yi görmüyorum, neden alternate yapmamış ?
