HƯỚNG DẪN LẬP TRÌNH KEIL C CHO 8051-[Chỉ dành post bài hướng dẫn]

[Timang]

Cám ơn ban NgoHaiBac về bài viết trên . Mình mới vừa chập chững bước vào phần mềm này . Mong bạn hướng dẫn tiếp . Cám ơn nhiều .

[HD.03]

các bác cho e hỏi. e muốn học lập trình C cho vđk vậy e nên bắt đầu từ đâu.
trước e có học qua các vòng lặp for vs do-while nhưng còn mơ hồ quá.
Mong các bác tư vấn giúp.
Thân.

e có thắc mắc là tại sao nhiều lúc lập trình mà người ta cứ khai báo #define F P0 . rồi sử dụng F thay cho P0 vậy mọi người ??? liệu việc sử dụng F với việc sử dụng P0 trực tiếp truyền giá trị và thao tác bit thì nó có khác nhau không ???
