Xin giúp đỡ về set ip tĩnh cho Ethetnet shield

Xin chào các bác !
Em có mua 01 bộ Ethetnet shield & Arduino ( nó là bộ box switch reset pc từ xa), người bán đã config sẵn hết. Nhưng giờ em muốn set IP tĩnh cho cái box này (default nó lấy IP Auto, nhưng thỉnh thoảng bị xung đột IP hay sao mà no cứ offline)
Em có down cái soft Arduino 1.8.5, nhưng ko biết connect với cái Box & load data, sửa IP tĩnh theo ý mình như thế nào ạ ? Mong các bác hướng dẫn, thanks

Hi @limann
Bạn set như bạn phía trên chỉ là được code bên dưới.
Tuy nhiên bạn phải kêu ng bán gửi bạn code để sửa nha bạn.
Thân!
