    Số cột dữ liệu của Led matrix 8x32

    VD em có đoạn code như sau:
    Code:
    ORG 0000H
mov DPTR,#string1
LOOP: MOV R2,#0 
LOOP2: MOV R5,#78h 
LOOP1: MOV R0,#0 
MOV R1,#0 
LOOP3: MOV A,R1
MOV P2,A 
MOV A,R0
ADD A,R2
MOVC A,@A+DPTR 
MOV P1,A 
CALL DELAY1
INC R0
INC R1
CJNE R1,#32,LOOP3
DJNZ R5,LOOP1
INC R2
CJNE R2,#255,LOOP2

    trong chương trình có câu lệnh là:
    CJNE R2,#255,LOOP2 tức là số cột dữ liệu là 255 cột.
    255(dec) = 11111111(bin) = FF(hex) - max8bit
    lên khi tăng nó lên lớn hơn 255 tức là từ 256 trở đi thì.
    256(dec) = 000100000000(bin) = 100(hex) - 12bit
    nhưng 89cXX là họ VXL 8bit lên khi tăng lên 256 sẽ làm dữ liệu bị cắt xén bớt.
    lên em muốn hỏi các bro là có code hay cách nào để cho led matrix có số cột dữ liệu lớn lớn hơn 255 không, hay quét vô hạn cũng dc. chứ để thế này đem đi tặng sn bx thì k viết dc nhiều chữ vì nó giới hạn chỉ có số cột dữ liệu là 255 mà.

    thanks

      tăng dptr (dptr=16bit)
      pác có thể nói rõ hơn k, sửa dòng dptr thành dptr=16bit ah
      em sửa nó báo lỗi mà.

          trong chương trình có câu lệnh là:
          CJNE R2,#255,LOOP2 tức là số cột dữ liệu là 255 cột.
          255(dec) = 11111111(bin) = FF(hex) - max8bit
          lên khi tăng nó lên lớn hơn 255 tức là từ 256 trở đi thì.
          256(dec) = 000100000000(bin) = 100(hex) - 12bit
          nhưng 89cXX là họ VXL 8bit lên khi tăng lên 256 sẽ làm dữ liệu bị cắt xén bớt.
          lên em muốn hỏi các bro là có code hay cách nào để cho led matrix có số cột dữ liệu lớn lớn hơn 255 không, hay quét vô hạn cũng dc. chứ để thế này đem đi tặng sn bx thì k viết dc nhiều chữ vì nó giới hạn chỉ có số cột dữ liệu là 255 mà.

          thanks

                Thanks pác. nhưng em tò mò muốn hỏi chút!!!
                Đây là code dành cho mạch Led Matrix 1 màu 8x32.
                Pác có thể nâng nó lên thành code cho mạch LED Matrix 2 màu 8x32 dc không.
                Nghĩa là tạo 2 chương trình con như trên và hai chương trình xuất mã cột ở các cổng khác nhau, để mối chương trình điều khiển 1 led matrix khác nhau (VD: chương trình 1 điều khiển led matrix màu đỏ, chương trình 2 điều khiển led matrix màu xanh).
                Còn chương trình chính có nhiệm vụ gọi 2 chương trình này ra. khi gọi chương trình 1 thì khóa chương trình 2 và khi gọi chương trình 2 thì khóa chương trình 1.
                thanks

                  quên mất.
                  đây là file mô phỏng led matrix 8x32

                  )
                  design bằng pro 7.7 sp2 đấy nhé. bro nào xài pro 7.6 trở về trc không đọc dc đâu.
                  nếu chưa có bản pro 7.7 sp2 thì vào link sau down nhé:

                      Thanks pác đã nhiệt tình giúp đỡ nhưng em hơi gà lên k hiểu lắm.
                      Vậy khai báo dữ liệu cho led xanh và đỏ như thế nào vậy.
                      hai màu led matrix có dữ liệu # nhau mà.
