de tai thiet ke mach dieu khien thiet bi dien bang sms dung sim 900

[truong1993]

các a giúp e với.hiện nay mạch của e đã xong phần cứng nhưng khi kết nối thị lcd vẫn không thấy tín hiệu gì hết.e có thử cái code coi thử có hoạt động ko thì ra thế này à.ai có tài liệu gj về đề tài này hay kinh nghiệm gjup e với.2tháng nữa là e bảo vệ rùi.

code của e đây ah.đã chuyển sang filr hex mà cũng ko chạy:
