hỏi về code C cho 89c2051 + 74hc595 điều khiển led ma trận 8x8

[darrenshan]

mình nối chân P3_3 với chân 11 của 595,chân P3_4 với chân 14, chân P3_5 với chân 12, mình quét bằng 595,mức 1,port 1 của 2051 mức 0,vì port 1 khi ở mức 1 thì áp các chân ko đều,cụ thể P1_0,P1_1 chỉ ra có hơn 2V nên ko muốn dùng port 1 làm mức 1,mình có thử viết code port 1 quét mức 0 nhưng ko chạy theo ý muốn

sau đây là code mình viết,chạy đúng ý được nửa sau


#include<AT892051.h>

sbit SCK = P3^3;
sbit DATA = P3^4;
sbit SCL = P3^5;
