Code sai ở đâu??????ai giúp em với...

[quangthangbk]

Các pác ơi giúp em với.huhu.Em đang làm đồ án môn học, cụ thể là đồng hồ kèm đo nhiệt độ hiển thị bằng LCD nhưng em thử viết code thì không biết sao không chạy được. Bác nào giúp em với.hic.thứ 6 em phải nộp rồi.huhu
code của em như sau:

Em đính kèm mạch nguyên lý của em.

[tranpic]

mình chưa coi hết được nhưng mình thấy thế này nhé.

chỗ kiểm tra lcd busy của bạn sao lại viết hàm While(1) nhỉ cái này chỉ cần viết như sau:
void busy()
{
rs=0;
rw=1;
P2_7=1;
while(P2_7)
{
e=0;
e=1;
}
}
