如何从网络发送信息到 LCD
我曾见过能够向 Logitech LCD 面板发送信息的应用程序,并在几年前使用过它。目前,我有四个小型液晶面板。两个是 CrystalFontz 633,一个来自 1U EMC 数据存储盒,另一个来自旧的基于以太网的 KVM,所以我不知道它的功能是什么。使用 Flex Builder 或 Visual Studio,是否可以创建网页或离线应用程序(例如 Adobe Air、Mac Widget 或 Windows 7 Gadget),可以检查文本并将其馈送到 USB 或串行连接液晶显示设备?如果它是一个离线应用程序,那么能够与基于 Web 的 php 脚本对话并将数据转发回 LCD 将非常方便。
I have seen applications capable of sending information to Logitech LCD panels and played with that a bit a few years ago. Currently, I have four small LCD panels. Two are CrystalFontz 633s, one came from a 1U EMC data storage box and one was taken from an old ethernet-based KVM, so I've no idea what it's capabilities are. Using either Flex Builder or Visual Studio, is it possible to create either a webpage or an offline app, such as for Adobe Air, Mac Widget, or Windows 7 Gadget, that can check for and feed text to a USB- or serial-connected LCD device? If it's an offline app, it would be very convenient to be able to talk to web-based php scripts and relay that data back to the LCD.

PHP 可以与串行端口通信,幸运的是,有人已经完成了繁重的工作:
http://code.google.com/p/php-serial/
之后,这只是一个与LCD 具有其理解的任何指令集。该信息应该在开发人员手册中,除非您想走有趣的路线并发送随机字符直到发生事情:)
PHP can talk to serial ports and fortunately for you someone has done the heavy lifting already:
http://code.google.com/p/php-serial/
After that it's just a question of talking to the LCD with whatever set of instructions it understands. That information should be in the developer manual unless you want to go the fun route and send random characters until something happens :)
不要直接写入 LCD。那只是痛苦。相反,编写一个小型客户端应用程序来与您的 Web 服务器通信,并在 LCD 屏幕上显示数据。
Don't write directly to LCD's. That's just pain. Instead, write a tiny client application that will talk to your web server, and display the data on your LCD screens.
