Có vẻ trình biên dịch không hiểu "P1" là cái giống gì !
Bạn thử thêm $MOD51 ở dòng đầu tiên.
Trong thư mục làm việc phải có file MOD51 (định nghĩa các thanh ghi của 8051)

Em không bết phải khắc phục làm sao...có bác nào giúp mình với...thanks!

Lại thêm cái ông "lập.....bập......trình" kiểu nông dân này nữa

chết mất .Nhìn đoạn trên có vẻ như bác này làm led sign chẳng biết gì về cái gọi là "thuật giải " hay "cấu trúc lập trình" là gì cả nhể .

bạn muốn học thêm về vdk nên đọc sách "cấu trúc và lập trình vdk 8051" nên lập trình bằng keil C sẽ dễ dàng vì thư vện rất đầy đủ.nếu lập trình dùng ASM thì không cầ khai báo thư viện
Goodluck

lehung883 chê người khác quá nha. bạn nghỉ ai củng biết như bạn hả?.người ta chưa biết người ta mới đi từ cái cơ bản.
ông đọc cuốn sách "chuyên đề : VI ĐIỀU KHIỂN HỌ MSC-51" của VƯƠNG KHÁNH HƯNG CHƯA.
người ta củng chỉ cách lập trình giống như bạn jackchan1987. (trang 160)
ông cha ta có câu" cười người hôm trước hôm sau người cười"

Uhm...vậy thì mình nên sửa như thế nào...mình đang lập trình bằng con 89C51...!

Lần sau bạn nên gửi dưới dạng file,chứ đọc thế này hành hạ đôi mắt quá trời luôn!chác là bạn đang dùng trình biên dịch là ASM51 đúng không?nếu dùng trình này thì nó sẽ không định nghĩa được các địa chỉ đâu,cách đơn giản là bạn có thể sửa lại các địa chỉ theo như bảng địa chỉ tôi gửi dưới đây.Ví dụ:P0.0 là 080H,P0.1 LÀ 081H ....Thế nhé!
