Gphone Clock (Dam Clock V1.0) sử dụng GLCD 128×64 trong máy bàn không dây Homephone của Viettel và máy Gphone.
Sau khi tháo ra thì ngoài số mã PCB-S68063-1 V02 thì không có thêm thông tin gì khác, lên mạng tìm thì không thấy bất cứ tài liệu datasheet gì nói về con này.
Rất may mình đã tìm được thư viện giao tiếp và sơ đồ chân của Vũ Văn Thái kèm theo bản test mà mình đã đăng lần trước và thấy các hàm đọc, ghi,hiển thị dữ liệu cũng na ná như 1 số dòng LCD khác nên mình quyết định chinh phục em nó cho bằng được.
Sau vài ngày tìm hiểu về cái LCD này mình quyết định cho ra sản phẩm Gphone Clock (Dam Clock V1.0)
Xem thêm:
- Đồng hồ thời gian thực (Read Time Clock – DS1307) sử dụng Arduino
- Đồng hồ số hiển thị trên LED 7 đoạn dùng 89S52 và DS1307
- Hiển thị thời gian thực (RTC DS1307) lên LCD16x2 bằng giao tiếp I2C trong môi trường Arduino
Tuy rằng còn nhiều chức năng thiếu : Báo thức, remote , bật tắt đèn nền … nhưng mình thấy khá hài lòng vì tính ĐỘC và chưa đụng hàng với bất kỳ sản phẩm nào.
Mình cũng quyết định chia sẻ full code C bản Gphone Clock (Dam Clock V1.0) này để anh em nghiên cứu .
Hy vọng rằng anh em có ai share hoặc thương mại thì cũng bớt ra 1 vài dòng chót cho tác giả để mình thấy công sức của mình bỏ ra là hoàn toàn xứng đáng…Xin cảm ơn!

Giới thiệu màn hình GLCD 12864 Homephone Viettel hoặc GPhone VNPT
Màn hình GLCD 12864 HOMEPHONE/GPHONE từ điện thoại Viettel hoặc Vinaphone
Xem hướng dẫn sử dụng chi tiết ở đây nhé:
Hướng dẫn sử dụng glcd ST7565 homephone và chia sẻ thư viện
- Sử dụng IC điều khiển ST7565
- Điện áp: 3,3 – 5,5 VDC (Không khuyến khích sử dụng 5V)
- Kích thước viền ngoài: 60 x 90.5 x 10 mm
- Kích thước màn hình: 70 x 47 mm.
- Độ phân giải: 128px x 64px
GLCD của máy điện thoại không dây Gphone do hãng ZTE sản xuất theo đơn đặt hàng của VNPT.
Ưu điểm của LCD này là đẹp, rẻ có thể đi nhặt đồng nát hoặc xin được, vì giá những con GLCD trên thị trường cũng khá khó kiếm
GLCD có đèn nền mầu trắng hoặc màu vàng sẫm tùy đời máy Gphone
Giao tiếp SPI 4 line tiết kiệm chân MCU, điện áp hoạt động theo mình dò được khoảng 2.2-3.3V (2.5V) và các tính năng khác mình có nêu rõ trong ghi chú Code.
Điều đáng nói ở đây là tài liệu về con GLCD này là không có trên mạng lên việc xác định chân cẳng hoàn toàn bằng kinh nghiệm và chip driver cũng noname luôn, nhưng thật may là mình đã test thử với con ST7565, ST7567… mà tìm ra tập lệnh tương thích với nó.
Như vậy từ bây giờ các bạn có thể sử dụng nó như một Text LCD 20×8 với bộ font được bạn Lê Đắc Đảm biên soạn sẵn và chế độ Graphic cho những bạn nào thích đồ họa đen trắng 😀
Sau đây là sơ đồ nguyên lý chung cho GLCD: Tất cả các LCD trong máy Gphone đều giống nhau!!!!
Chú ý: Vị trí chân của LCD này khác so với LCD 9 chân như sau
- Serial input data = SDA or SI or DIN or MOSI ( chân 7 của màn hình )
- Serial clock = SCL or SCK or SCLK ( chân 3 của màn hình )
- Data/command select = RS or AO or DC ( chân 4 của màn hình )
- LCD chip reset = RST or REST ( chân 2 của màn hình )
- LCD chip select = CS or CE or SS or EN or SCE ( chân 8 của màn hình )
Màn dùng điện áp <5V nên khi cấp nguồn + cho chân 9 của màn hình từ khoảng 2,5-3,3V hoặc dùng cầu chia áp bằng 2 điện trở 10K.
Nguồn (-) cấp vào chân 1 và 10 của màn hình.
Cấp nguồn cho 2 chân led nền là 5 và 6 của màn hình
