Chương trình mình viết cho đồnếg hồ số có thay đổi giờ và đặt giờ hẹn (lưu trong eeprom. Đồng hồ chạy bình thường, lưu giờ eeprom bình thường, báo giờ bình thường (mình dùng ngắt ngoài sử dụng chân SQW của DS1307-1Hz).
Nhưng khi thêm đoạn code bấm phím - hiển thị menu thì bị lỗi.

* Nếu không che đoạn code đó và không có khai báo #org thì báo lỗi "out of rom".
* Nếu mỉnh che bớt phần code menu từ chức năng _22 trở đi và có khai báo #org thì chương trình chạy bình thường.
* Nếu có khai báo #org và chỉ cần thêm 1 câu lệnh thôi thì compile không lỗi nhưng chương trình không bắt phím được.
Ai đã làm rồi và có kinh nghiệm sửa lỗi này thì giúp mình một chút. Cám ơn nhiều.

* Nếu không che đoạn code đó và không có khai báo #org thì báo lỗi "out of rom".
* Nếu mỉnh che bớt phần code menu từ chức năng _22 trở đi và có khai báo #org thì chương trình chạy bình thường.
* Nếu có khai báo #org và chỉ cần thêm 1 câu lệnh thôi thì compile không lỗi nhưng chương trình không bắt phím được.
Ai đã làm rồi và có kinh nghiệm sửa lỗi này thì giúp mình một chút. Cám ơn nhiều.
