Visual basic6 + 18f4550 usb

[ibrahim626]

Öncelikle Herkese merhaba benim bir sorum olacak , ben suan PIC 18F4550 ile usbden led yakmaya çalışıyorum bağlantıyı sorunsuz kurdum işlemci ile haberleşebiliyorum fakat ledleri istediğim gibi yakamıyorum. programda toplamda 16 adet buton var bunlar 8 ledi yakıp söndürmek içindir, benim istediğim çalışma kosulu :
butonlardan basılı olana karsılık o ledi yakmak yani hangi buton yada butonlar basılı ise karsılık gelen ledlerı yakmak
benim programımın çalışması iste şöyle :
1. butona basıyorum portb'nin 0.ledi yanıyor
2. butona bastığımda ise port.0'daki lled sönüyor 1.led yanıyor ben bunları birbirinden nasıl kontrol edebilirim ? nasıl bi program yazmalıyım vb'de henuz biraz acemiyim.
