Help lập trình pic16f877a giao tiếp màn hình LCD nokia3310
Hi.
Em đang nghịch cái màn hình nokia3310 kết nối với vi điều khiển để hiển thị một số hình ảnh mà em chưa biết cách xử lý như thế nào cả. Em có sử dụng phần mềm fastLCD để truy xuất file ảnh ra mã hex nhưng từ mã đó em không biết thao tác như nào để vi điều khiển có thể nhận nó và xuất ra để hiển thị trên màn hình cả. Mong các vị tiền bối chỉ giáo giúp em, em viết code trên CCS! Em cám ơn nhiều! |

Bạn tham khảo luồng này nhé , nhưng code viết bằng Picbasic pro . Ngôn ngữ này rất dễ hiểu và tiếp cận .

Đầu tiên của chương trình , ta phải set lcd , bằng các dòng sau đây : Code:
LOW DC ' TRUYEN LENH LCD 3310 LcdData= $21: GOSUB LCD_ByteOut ' CODE %00100001 -> PD=0:CHIP ACTIVE ; V=0:HORIZONTAL ; H=1:LENH LCD MO RONG LcdData= $C8: GOSUB LCD_ByteOut ' CODE %11001000 SET LCD Vop (CONTRAST) LcdData= $06: GOSUB LCD_ByteOut ' CODE %00000110 SET TEMP COEFFICENT = 2 LcdData= $13: GOSUB LCD_ByteOut ' CODE %00010011 LCD BIAS MODE LcdData= $20: GOSUB LCD_ByteOut ' CODE %00100000 -> PD=0:CHIP ACTIVE ; V=0:HORIZONTAL ; H=0:LENH LCD CO BAN LcdData= $0c: GOSUB LCD_ByteOut ' CODE %00001100 LCD IN NORMAL MODE - NEN TRANG CHU DEN . Ta truyền dữ liệu chứa trong biến LcdData ra màn hình . 2 chân DTA và CLK là 2 chân giao tiếp với lcd . Bạn chú ý lúc này chân DC = 0 tức là ta đang truyền lệnh nhé . Code:
LCD_ByteOut: SHIFTOUT DTA,CLK,1,[LcdData] RETURN chương trình con như sau : chân DC được kéo lên mức 1 tức là truyền dữ liệu . Code:
XOA_GLCD : PosX=0:PosY=0:GOSUB LCD_GotoXY ' DEN VI TRI HANG = 0 - COT BANG 0 HIGH DC ' TRUYEN DU LIEU FOR Chr=1 TO 252 LcdData=0:GOSUB LCD_ByteOut LcdData=0:GOSUB LCD_ByteOut NEXT Chr RETURN code cho chương trình LCD_GotoXY như sau : DC = 0 là để truyền lệnh . PosY được "or" với %01000000 , truyền lệnh ra lcd PosX được "or" với %10000000 , truyền lệnh ra lcd tại sao y cần "or" với %01000000 và x cần "or" %10000000 thì bạn xem lại datasheet của lcd nhé . Code:
LCD_GotoXY: LOW DC LcdData=%01000000 | PosY :GOSUB LCD_ByteOut LcdData=%10000000 | PosX :GOSUB LCD_ByteOut RETURN +Sau khi vẽ xong màn hình bằng chương trình fastLCD , dịch ra ta sẽ được 1 tập các giá trị . +Ta dùng 1 vòng lặp for để lấy từng giá trị và cho hiển thị ra lcd . Câu lệnh LOOKUP2 I là để lấy giá trị theo vị trí I . Vì I là biến chạy từ 0 cho đến 504 cho nên ta sẽ lấy được tuần tự các giá trị có trong tập để hiển trị ra lcd . Code:
MAIN_CLOCK_TEMP_SCREEN :
PosX=0:PosY=0:GOSUB LCD_GotoXY ' DEN VI TRI HANG - COT BANG
FOR I = 0 TO 504 ' VE MAN HINH

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!
