基于PIC单片机的低功耗读卡器硬件设计
<P>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，并大胆简化了许多传统的设计电路。<BR>关键字： 读卡器， 单片机， 串口窃电</P>

基于MSP430F1611单片机的音频信号分析仪设计
<p>
为了使音频信号分析仪小巧可靠，成本低廉，设计了以2片MSP430F1611单片机为核心的系统。该系统将音频信号送入八阶巴特沃兹低通滤波器，对信号进行限幅放大、衰减、电平位移、缓冲，并利用一单片机负责对前级处理后的模拟信号进行采样，将采集得到的音频信号进行4 096点基2的FFT计算，并对信号加窗函数提高分辨率，另一单片机负责对信号的分析及控制显示设备。此设计精确的测量了音频信号的功率
