18F8722 ve CCP3 pwm çıkış sorunu

Maxim · 27 Kasım 2013, 15:04:04

18F8722 ile RGB led kontrolü yapmaya çalışıyorum

mavi rengin bağlı olduğu PORTG.0 ccp3 çıkışında sıkıntım var
HPWM ile sürmeye kalkınca yeşil led yanıyor!
(mavi çıkışı high veya low yapınca çalışıyor)

kırmızı ve yeşil çıkışlar düzgün çalışıyor

bir türlü çözemedim
problem proteus simulasyonunda da mevcut, gerçek devrede de.

led kontrolü için kullandığım basit proton+ kodu bu.

hocam simülasyon dosyasınıda yükleseydin.

pwm.c · 27 Kasım 2013, 20:28:44

aynı kodları PBP'ya uyarlayarak ve ayrıca CCS ile de denedim. ikiside sorunsuz çalıştı.
sanırım proton kusuru olmalı.

hocam Enhanced Capture 3 input/Compare 3 output/ bu pinde compare var bunu iptal ettinizmi?

hocam Enhanced Capture 3 input/Compare 3 output/ bu pinde compare var bunu iptal ettinizmi?

dosyaları ekledim
o pinde compare mi var?
hemen bakayım

edit: yanlışın var PORTG.0 da comparator yok

Hocam pdf sayfa 30 da

Enhanced Capture 3 input/Compare 3 output/
PWM 3 output.
ECCP3 PWM output A.

Maxim · 27 Kasım 2013, 21:01:06

compare - comparator karıştı
evet compare var doğru
şöyle bir deneme yaptım
CCP3CON=%00001100 yazıp denedim yani ccp3 ve diğerlerinide pwm moda set ettim gene aynı

evet teşekkürler oldu böyle ama her çıkışa aynısını yapmak gerekti yoksa gene karışıyor yeşil ile mavi.
acaba bu bir bug mıdır? karar veremedim

mesela hpwm.inc yardımcı dosyası var protonun
onu kullandım denedim, o da düzgün çalıştı
tabi onun içinde bir sürü yardımcı tanımlama var

şöyle tam oluyor
