LẬP TRÌNH VI ĐIỀU KHIỂN 8051 Mục tiêu: Hiển thị chữ tiếng việt lên led ma trận sử dụng led ma trận 8x8, chữ chạy từ phải qua trái (cho dễ đọc) Hiệu ứng: Chữ thường dài phần hiển thị, nên sau hiển thị tất cột, sau cột cuối trơi hết lặp lại Có thể hiển thị nhiều chuỗi nối tiếp Điều khiển: Mạch tự động chạy, có nút bấm: nút pause/unPause; nút next (để sang chuỗi tiếp theo) thấy bé để hiển thị tiếng việt Cuối định dùng hàng led8x8 đủ độ cao để hiển thị tiếng việt có dấu Mạch thật: chưa làm ^^ Mạch mơ phỏng: sử dụng AT89C51 IC loại 74HC595, cuối dùng để xác định cột cần quét, dùng để đưa liệu bít
