Chào các bạn, lâu rồi không đụng món này. Không biết trên dienvietnam có ai đã từng gặp lỗi như mình chưa. Số là có ứng dụng mình làm giao tiếp hid trên 18f4550 chạy trên win 7,xp Ok hết.
Nay mới up lên win 10, thì cấm vào báo lỗi này mới đau chứ lay hoai mãi mà không biết sữa thế nào nên lên đây hỏi xin ý kiến các tiền bối.
Lỗi: CODE 43
Nghi ngờ là do File descriptor chưa hợp lệ mình dùng HIDterminal tool của mikro c soạn file descriptor cho thiết bị là usb, trình biên dùng của mikro C.
Cám ơn mọi người.
