                                    ai có thể viết giúp em chương trình điều khiển nhiệt độ hiển thị ra màn hình lcd được không ạ? có cả khối đo nhiệt độ nữa
                                    các chân Rb* ra màn hình lcd
                                    các chân Ra* ra khối đo nhiệt độ
                                    các chân Rc* ra Rp4
                                    các chân Rd* ra Rp1
                                    cám ơn ạ!

                                        Có ai giúp em học Pic với không? Em học mãi mà không hiểu gì? Huhu. Mà em đang phải thiết kế mạch. Ai giúp em với. Quay video cho em thì càng tốt. em xin cảm ơn!

                                            Cho em hỏi câu này. Bình thường em dùng PIC18F4431 để đk 3 động cơ DCthì ko sao. Giờ em muốn dùng Pic16F877A để điều khiển ba động cơ DC thì có thế được ko ạ. Em dùng hai chân CCP thì không vấn đề j rồi. Còn một động cơ nữa thì làm sao được ạ. Mong các bác giúp đỡ

                                                    cho hỏi e hỏi viết chương trình cho ngắt RB0 trong pic 16f877a khi đo khoảng thời gian cho 1 xung chữ nhật trong 1 chu kì như thế nào
