  • 基于PIC单片机的低功耗读卡器硬件设计

    基于PIC单片机的低功耗读卡器硬件设计:本文提出了一个完整的基于串口的智能读卡器子系统设计方案并将其实现。读卡器的设计突出了小型化的要求,全部器件使用贴片封装。为了减小读卡器的体积,设计中还使用了串口窃电的技术,使用串口信号线直接给读卡器供电。为此,读卡器使用了省电的设计,采用了省电的集成电路,并大胆简 ...

  • Emulating a synchronous serial

    The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...
