基于数字信号处理的超声手术刀电源控制电路设计与实现
<p>目的:自主研制一款超声手术刀电源控制系统,以减少能量的消耗,维持手术刀的正常温度。方法:对超声换能器在谐振附近的等效电路建立模型,并设计基于数字信号处理(DSP)的超声手术刀的硬件控制系统。结果:经对电源控制系统的电路和工作性能测试,生成的电流和电压的有效值等参数,能够及时调整电源的频率,并达到预期的功能指标,使超声手术刀工作在谐振状态。结论:以DSP为核心设计的超声手术刀电源控制系统,测试
基于STM32单片机控制的智能水杯设计
<p>本设计介绍了一种基于STM32单片机控制的智能水杯,可利用插口式电源或无线充电底座为加热器提供能量,并在达到某种饮品所需温度时进行保温。水杯内置充电电池,可选用USB接口或无线充电。在水杯内部设置无线模块,用户利用手机App与水杯进行匹配进行加热操作,加热完后水杯会通过手机App和液晶显示屏实时反馈液体温度,通过指示灯显示电量情况等,给用户进行提醒。该智能水杯设计创新,实用价值较高。</p>
基于MSP430单片机及FPGA的简易数字示波器
<p>数字示波器功能强大,使用方便,但是价格相对昂贵。本文以Ti的MSP430F5529为主控器,以Altera公司的EP2C5T144C8 FPGA器件为逻辑控制部件设计数字示波器。模拟信号经程控放大、整形电路后形成方波信号送至FPGA测频,根据频率值选择采用片上及片外高速AD分段采样。FPGA控制片外AD采样并将数据输入到FIFO模块中缓存,由单片机进行频谱分析。测试表明:简易示波器可以实现自
多功能电子药箱的设计与实现
<p>基于药物治疗在临床治疗中的重要性,分析目前服药提醒装置存在的不足,以STM32F103VET6单片机为控制核心,设计了一种多功能电子药箱。该系统包括显示模块、语音模块和数据存储模块。显示模块通过触摸屏电路和LED指示灯电路,与语音模块相配合,实现了服药提醒及指导的功能;数据存储模块通过EEPROM存储电路,能够实现掉电时服药信息不丢失的功能。并且为了实现电子药箱的智能化控制,开发了手机APP
J-LINK下载器
<p style="text-align: justify;">首先下载软件，解压软件，安装在程序中找到SEGGER,选里面的J-FLASH，进入界面，刚开始的那个界面可以忽略，不用建project也可以；单击菜单栏的“Options---Project settings”打开设置，进行jlink配置;正在General选项，选择“USB”，一般都是默认配置，确认一下即可;然后在CPU选项，选择芯
