A- Gerekli Malzemeler:<\/strong><\/p>\n

1 – Bilgisayar
\n2 – 2 adet RS232 kap\u0131s\u0131 bulunan bilgisayar yada USB-Seri d\u00f6n\u00fc\u015ft\u00fcr\u00fcc\u00fc<\/p>\n

Bu uygulamada ISIS ortam\u0131nda RS232 sim\u00fclasyonu yapaca\u011f\u0131z. Bunun i\u00e7in ISIS\u2019in COMPIM nesnesini kullanarak bilgisayar\u0131n seri kap\u0131s\u0131ndan veriler g\u00f6nderece\u011fiz ve bu verileri bir program arac\u0131l\u0131\u011f\u0131yla okuyaca\u011f\u0131z. Ayn\u0131 \u015fekilde bilgisayardaki programdan bir veri g\u00f6nderildi\u011finde de devremiz bu veriyi alabilecek.
\nBunu yapabilmek i\u00e7in bilgisayar\u0131n 2 seri kap\u0131s\u0131n\u0131 kullanaca\u011f\u0131z. E\u011fer bilgisayar\u0131n\u0131zda seri kap\u0131 yoksa veya bir tane varsa (ki bende 1 tane var) USB-Seri \u00e7evirici kullanarak USB kap\u0131s\u0131n\u0131 seri kap\u0131 gibi kullanabilirsiniz.<\/p>\n

<\/p>\n

C- Uygulama:<\/strong><\/p>\n

PIC\u2019e seri kap\u0131dan \u201c1\u2033 karakteri gelirse PIC bu karakteri geri yollayacak, \u201c2\u2033 karakteri gelirse \u201cMerhaba\u201d mesaj\u0131n\u0131 yollayacak ve \u201c3\u2033 karakteri gelirse \u201c3\u2033 karakterini iki ile \u00e7arp\u0131p geri yollayacak. Di\u011fer veriler i\u00e7in ise verinin alg\u0131lanamad\u0131\u011f\u0131na dair bir mesaj g\u00f6nderecek.<\/p>\n
