摘要
针对国内大多喷码机依赖于价格高昂的进口产品,且靠单片机系统控制,具有体积大、操作繁琐等缺点,提出设计了具有便携、人机交互简单、价格低廉等众多优点的喷码机;采用Windows CE嵌入式操作系统作为软件支持,以S3C2440核心板作为硬件支持,通过深入分析相关硬件的工作原理及软件的运行机制,设计出了XJ128喷头与S3C2440核心板的硬件连接和驱动程序的软件实现;通过分析示波器测量出的SPI管脚信号波形,符合XJ128喷头的时序逻辑,实验验证此程序运行稳定,能正确控制喷头,为国内喷码机行业的发展提供了技术性的支持。
According to most of inkjet printers in our country depend on imported products which are costly, and controlled by single chip microcomputer, which have many disadvantages of large size, cockamamie manipulation and so on, the inkier printers which have the characteristics of portability, simply human computer interaction and low cost are putted forward. Using the Windows CE embedded opera- tion system as software support, and the S3C2440 core plate as hardware support, designning the hardware connection between XJ128 print --head and S3C2440 core plate and implementing the software of the driver through analyzing the operating principle of the related hardware and the operating mechanism of the software in depth. Through analyzing the measurements of SPI pins＇ signal waveform by oscilloscope, it conforms to the sequential logic of XJ128 print-head, Experiments prove that the driver runs well and could control the print--head correct ly. Providing the technical support for the development of domestic inkjet printers.
