stm32f103c8 aynı anda pwm çıkışları çalışmıyor

FMY · 14 Kasım 2018, 19:16:27

merhabalar, bahsettiğim entegreyi cube mx den tüm kanallarını aktif ediyorum. ancak hal_tim_pwm_start fonksiyonu ile çıkışlarını aktif ettiğim halde aynı anda 2 den fazla kanaldan pwm alamıyorum. sebebi ne olabilir

Alabilirsiniz, kodunuzu eklerseniz daha çok yardımıncı olabiliriz.

Sebebi programinizi yanlis/eksik yazmaniz olabilir.

Datasheetin ilgili bolumlerini sabirla yavas yavas sindire sindire okuyunuz.

Hocam anladığım kadarı ile TIM2 ayarlarını (Period,Pulse) yapmamışsınız.
TIM1 ayarlarını TIM2 içinde yaptım deneye bilirmisiniz ?
