h köprü sürmek için pwm üreten mikroişlemci önerileriniz.

[berkay_91]

bu program Atmega8A da sinüs sinyali üretmek için, Atmelin pwm çıkış bacağına RC filter bağlamayı unutmayın
(R=10 k ohm C=10nF olabilir)

Yanlış anlamayın ama pic haric sorduğum halde niye ısrarla pic öneriliyor anlam veremiyorum

kusura bakma sadece ilk satırı okuyup yorum yapmışım

[ohacagatay]

atmega164/324/644P  'yi kullanabilirsin, atmega16,32,64 ile aynı şekilde programlanıyor fakat 6 adet timer 'ı var
0A,0B,1A,1B,2A,2B sanırım yeterli olucaktır

attiny bile iş görür hocam bir analog giriş ikide pwm çıkışı bir adette dijital giriş yeticek şimdilik.

elimde birkaçtane stm8s003k3 var onlarla nasıl yapılır merak ediyorum açıkçası.

internetten bulma örnekdeğilde datasheetle biraz boğuşsak daha eğitici olacak.
