Hỏi về code msp430g2553

[kuku92]

Mình đang làm đồ án 2, sử dụng msp430g2553. Code của mình sử dụng với 1 con 8x8 thì chạy chữ rất chuẩn, nhưng khi đặt 5 con led 8x8 vào lại vẫn chạy như 1 con (chạy giống hệt nhau), các bạn giúp mình sửa code này với nhé. Giờ mình làm xong mạch rồi, nhưng code thì lại bị như vậy.
Code:
#include "msp430g2553.h"
int m,n,k;
// KHAI BAO CHAN /////////////
// PORT2.0 == data
// PORT2.1 == clk
// PORT2.2 == chot
//---------chuong trình con delay ----------
void delay(unsigned int t)
{
unsigned int i, a;
for(i=0;i<t;i++)
{
for(a=0; a<125; a++)
{}
}
}
