ST7787 芯片的SPEC,比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and 320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

学 习 ASP 页 的 最 佳 途 径 是 动 手 编 写 自 己 的 ASP 页 。 创 建 ASP 页 其 实 很 简 单 , 只 要 使 用 文 本 编 辑 器 将 脚 本 命 令 插 入 到 HTML 页 中 就 行 了 。 将 这 个 主 页 以 .asp 为 文 件 扩 展 名 保 存 , ASP 服 务 器 就 知 道 处 理 其 中 的 脚 本 命 令 了 。 若 要 查 看 脚 本 的 结 果 , 只 要 使 用 HTTP 协 议 在 Web 浏 览 器 中 请 求 查 看 该 页 就 行 了 。 也 就 是 键 入 ht tp://localhost/iishelp/iis/htm/tutorial/filename.asp 。 在 本 课 中 , 您 将 创 建 流 行 的 “ Hello World! ” 脚 本 , 方 法 是 从 教 程 中 将 HTML 和 ASP 脚 本 命 令 复 制 到 文 本 编 辑 器 中 。 当 您 在 文 本 编 辑 器 中 保 存 文 件 后 , 就 能 用 浏 览 器 查 看 脚 本 的 输 出 效 果 了 。
