利用VC实现汉字字模提取及串行通信

Withdrawing the Chinese Matrix and Realizing the COM Port Communication by VC

目前,单片机广泛地应用于许多实时工业控制和数据采集系统,极大地提高了工业设备的智能化。在单片机加显示器件构成的小系统中,需要经常用到汉字显示技术。如何得到汉字字模是汉字显示技术中首先必须解决的问题。并且,由于单片机的硬件资源很有限,寻址和计算能力都远低于PC机,显示汉字受到限制。因此将这个工作交给PC机,让PC机访问汉字库并提取汉字字模,再通过串口将汉字字模发送给单片机。通过该方法不仅极大地提高了汉字显示的效率还保证了可靠性!

At present, single chip compute is widely used in real-time industrial control and data acquisition system, which greatly increases the intellectualization of industrial equipment.A small system consisting single chip computer and display device often requires Chinese characters display technology. How to get Chinese fonts becomes the first important problem which has to be solved in Chinese characters display technology. Moreover, due to the limited hardware resource, addressing and computation ability are far inferior to that of PC, the ability of display of Chinese characters will be limited. Therefore, this work is taken over by PC, allowing PC to withdraw the Chinese fonts from Chinese character library and sending them to the single chip computer through the COM port. By this means, it enhances the efficiency of the display of Chinese character and ensures the reliability!
