18F25k22 PWM

Merhabalar bir 25k22 problemiyle yine karşı karşıyayım. EPWM modülünü kullanarak pwm üretmeye çalışıyorum, simülasyonda gayet başarılı çalışıyor ancak reelde ilgili çıkışlarda TIK yok. Çıkışları dijital olarak kontrol edebiliyorm ancak PWM lerde çıkış alamıyorum. Sizce nedendir?

Teşekkürler @mehmet hocam. Sabah deneyeceğim

Gece bakınca daha iyi çalışıyor kafam :). PMD0:1 registerlerini FF yapmışım. Bu tüm donanımlar arası haberleşmeyi kontrol eden bir register. Kapatınca düzeldi. Kusura bakmayın boşuna konu açtım.

@apsis boşuna değil aslında belki sizin karşılaşmış olduğunuz durumla çok kişi karşılaşacak en azından buradan görme şansları olabilir.

@HeCToR doğru söylüyorsunuz. Ben de bazen böyle küçük konulardan cevap bulabiliyorum. Teşekkürler

 Ben çözüm bulamamıştım, k serisinden başka seri kullanarak çözmüştüm. Sorunu çözmeniz benim içinde iyi oldu.

PMD = Peripheral Module Disable Herhangi bir Çevre birimini aktif/pasif yapmaya yarar default olarak hepsi 0 dır yani aktiftir. Özel bir amaç yok ise bu registerlere değer vermeyin. 46K80 de çok uğraştırmıştı :)
