Help!!! Led matrix 32x64

[thucpro]

Hiện tại mình đang làm đồ án led matrix. Dự tính là 32x64. Dùng phương pháp đưa dữ liệu vào cột - quét hàng đều dùng 74hc595. Mình mô phỏng trên proteus chỉ thấy chữ đứng yên không chạy qua trái hay qua phải gì cả. Nhờ mấy pác trên 4rum coi lại cái code và phần công suất của mạch dùm:
Code:
STAR:
CLKC BIT P2.0
DTC BIT P2.1
LATC BIT P2.2
CLKH BIT P2.3
