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.
Alıntı yapılan: fatihmehmet00 - 14 Kasım 2018, 19:16:27merhabalar, 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
Sebebi programinizi yanlis/eksik yazmaniz olabilir.
Datasheetin ilgili bolumlerini sabirla yavas yavas sindire sindire okuyunuz.
