Sau khi xóa chip xong, bạn thử đọc lại xem chip có thực sự bị xóa hay không. Nếu chip không thực sự bị xóa thì bạn không thể nạp chương trình mới vào được.

Thân,

Em nạp cho PIC16F877A

Đây là các thông báo của WinPIC ở phần Message: từ khi khởi động WinPIC, nạp file hex, chạy lệnh xóa rồi thử lệnh đọc về:


Info: Loading definitions for "PIC16F877A" from C:\Program Files\WinPic\devices.ini .

Tiếp theo là: quá trình khởi động WinPIC, rồi chạy lệnh Load & Program Device:

Các anh xem giúp em với, em không biết bị lỗi gì nữa
