摘要
提出一种全面的计算机与LED显示屏控制卡之间通信的通信协议,并且给出了用C++Builder编程实现串口通信的具体过程。其中以无灰度的双色屏为例子,重点给出了传输图片的方法,这种方法可以适用于各类显示屏控制卡的传输,对于双色屏和三色屏同样有效。结果证明:此种设计能够准确地从PC机向控制卡传输图片数据。
A comprehensive communication protocol between computer and LED display system was introduced, and the process of realizing serial communication by using C ＋ ＋ Builder was given. At the same time, a method of transmitting pictures by serial communication was intro- duces as well. This method can be used in transmission by all types of control card of LRD display screens, including two-colour screen and three-colour screen. The result is that the design can transmit data from PC to control card accurately.
