Keil ile Stm32f407 PWM programı ve nasıl değistiririm

[Birol]

Linkteki program mükemel bir şekilde çalışıyor. Keil ile yazılmış. Stm32f407disc.
PE8 ve  PE9 deattıme PWM üretiyor.
@ ama PWM çıkışı vermesi icin ilk olarak PA0 0v olması ve ikinci kısımda ise PA1 kısımdaki ADC 0v  ile 3,3v olması ve bunun 3voltu geçmesi gerekiyor. ve PD 13ten 3volt çıkış veriyor.

@PA0 1volt var ise ve PA1 zine 3 voltun üzerinde ise tek kanal PWM üretiyor ve PD12den 3volt çıkış veriyor.

simdi  birinci durumda ki 0-3,3v kısmını nasıl programa zarar vermeden silerim. Tşk

Birol, "simdi  birinci durumda ki 0-3,3v kısmını nasıl programa zarar vermeden silerim", tam anlaşılır değil. Ne yapmak istediğini net yazarsan

[Birol]

Karta yüklü program 2 farklı çıkış veriyor.

1) deattimelı PWM ve 3 volt çıkış ver.
2) tek kanal Pwm ve 3volt çıkış ver.

bu çıkışları verebilmesi için gerekli şartlar var.
Program 1
! PA0 da hariçi sabit bir kaynak üzerinden ilk önce 1 volt bağlımı diye kontrol ediliyor.
! 1 volt besleme bağlı ise program 2. aşamaya geciyor.
! Pa1 üzerinde yine bir hariçi ayarlanabilir bir kaynak üzerinden 0 ile 3.3 volt bağlı.
!  Bu değer 3 voltu gecince bır deattime PWM üret.
! PD 12'den 3 volt bir çıkış ver.
Program 2
! PA0 da hariçi sabit bir kaynak üzerinden ilk önce 0 volt(anahtar/şalter açık) bağlımı diye kontrol ediliyor.
! 0 volt besleme bağlı ise program 2. aşamaya geciyor.
! Pa1 üzerinde yine bir hariçi ayarlanabilir bir kaynak üzerinden 0 ile 3.3 volt bağlı.
!  Bu değer 3 voltu gecince bir tek kanal PWM üret.
! PD 13'den 3 volt bir çıkış ver.

program birdeki 0 ile 3.3 volt kontrol seçeneğini iptal etmek istiyorum.Programa herhangi bir zarar vermeden.
linkte programın tamanı yüklü. tşk

TŞK  ama olmadı galiba bütün programın değismesi gerekiyor.
