Merhaba sevgili yaz\u0131l\u0131mperver dostlar\u0131m, bu yaz\u0131mda sizler i\u00e7in faydal\u0131 olaca\u011f\u0131n\u0131 d\u00fc\u015f\u00fcnd\u00fc\u011f\u00fcm (\u00f6zellikle VxWorks i\u00e7in yaz\u0131l\u0131m geli\u015ftirenler) bir kod payla\u015f\u0131p, yeni repolar\u0131n duyurusunu yapmak istiyorum.<\/p>\n

\u00d6ncelikle, yeni repo’lar\u0131n duyurusunu yapay\u0131m. Daha \u00f6nce sizler ile, \u00e7e\u015fitli vesileler ile haftal\u0131k veya modern c++ yaz\u0131lar\u0131yla payla\u015ft\u0131\u011f\u0131m kodlar\u0131 (bu dahil) ve kulland\u0131\u011f\u0131m di\u011fer ara\u00e7lar\u0131 listeledi\u011fim repolara a\u015fa\u011f\u0131daki adreslerden ula\u015fabilirsiniz:<\/p>\n

Bundan sonra payla\u015faca\u011f\u0131m yaz\u0131larda olacak \u00f6nemli kod par\u00e7alar\u0131n\u0131 da bu repositoryler i\u00e7erisinde tutuyor olaca\u011f\u0131m.<\/p>\n

\u015eimdi gelelim yaz\u0131m\u0131n ba\u015f\u0131nda bahsetti\u011fim kod par\u00e7as\u0131na.<\/p>\n

G\u00f6m\u00fcl\u00fc yaz\u0131l\u0131m geli\u015ftiricisi olarak, kimi zaman RTC’leri veya di\u011fer saatleri g\u00fcncelleme ihtiyac\u0131 olabiliyor. RTC’leri genelde bir kere g\u00fcncelledikten sonra kullanabilirsiniz fakat zaman\/tarih bilgisini CMOS’tan da alabilirsiniz. \u0130\u015fte bu ama\u00e7la a\u015fa\u011f\u0131daki kodu<\/strong><\/span><\/a> kullanabilirsiniz:<\/p>\n
