18f4550 rb0 kesmesi

[bbs2006]

Merhaba
18f4550 de rbo kesmesi için yazılmış örnek bir yazılım varsa yardımcı olursanız sevinirim. ccs c için

hocam project wizart tan project olusturur iken inteerups bolumundeki 'external interrupt' yazan yeri isaretlediginizde kendisi otomatik olarak kodunuzun icine ext int fonsiyonunu dahil ediyor.

Mantığı ve MikroC örneğini blogumdaki linkte bulabilirsiniz.
