Xem cái chóng mặt rùi đấy !

Bạn Sunset_Pro có thể giới thiệu chút lý thuyết để mọi người dễ hiểu được chương trình bạn làm ko . Thank!

anh huudotb ơi, em mới gia nhập môn lập trình, đọc bài viết của anh em chẳng hiểu là lập trình cho con VĐK nào nữ.hic

đó là lập trình cho 8051 mừ bạn! hicihic!

dạo này ae bàn bạc rầm rộ quá.mình có cái này ae xem tạm
