Các phần thiết lập LCD và hiển thị ký tự hoặc giá trị lên LCD thì em đã làm được rồi, chỉ có phần lúc em tạo file ảnh từ phần mềm fastLCD xong em ra được mảng mã hex đó rồi nhưng khi em sử dụng vòng lặp for cho nó chạy nhưng nó lại báo lỗi, vì em viết trên CCS nên cấu trúc phần ctrinh trên này các lệnh em ko hiểu cho lắm. Anh đã từng viết qua chương trình CCS chưa,nếu viết rồi có thể giúp em phần hiển thị khung màn hình ở đoạn cuối được không anh.
Em cám ơn anh nhiều!
