lỗi của bạn là biến num bạn khai báo kiểu char ( 8 bit) => chỉ lên được đến 255 là đúng rồi

giúp em sửa code với, em sửa hoài mà không được

**kiepngheo** · 15-08-2013, 23:16

các bác có thể giúp e cái code này hk vậy

ở cái ngắt timer 1 k hiểu tại sao có cùng cái thời gian với ngắt timer 0 là "delay_mms(10,5)"
nhưng với timer 0 thì thiệu ứng lại chạy nhanh hơn rất nhiều với timer 1.

mong các bác giúp đỡ. thanks các bác nhiều nhiều lắm lắm.................

các bác có thể giúp e cái code này hk vậy

ở cái ngắt timer 1 k hiểu tại sao có cùng cái thời gian với ngắt timer 0 là "delay_mms(10,5)"
nhưng với timer 0 thì thiệu ứng lại chạy nhanh hơn rất nhiều với timer 1.

mong các bác giúp đỡ. thanks các bác nhiều nhiều lắm lắm.................

đa số trong các phần mềm nạp code điều có chế độ khóa chip mà.
niếu chíp đã khóa thì không thể nào đọc code từ chip nữa đâu

Code này mình chia sẻ lại nè. Bạn nhớ thanks tác giả trong code na..^^

Code:

}

không có source "Sound.h" thì code bạn đưa lên dùng sao được bạn?
