  • VCSELs and EELs

    InGaAs/AlGaAs semiconductor lasers come in threetypes: VCSELs and two types of EELs. The VCSEL, asits name implies, emits vertically, normal to the planeof the device, owing to cavity mirrors grown withinthe epitaxial material itself. The VCSEL’s circular beamhas a numerical aperture (NA) of roughly 0.2, or a fullangle of approximately 25 degrees.

  • J-LINK下载器

    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,选择芯片型号,先选择“Device”才能选择芯片型号,芯片型号,要根据你使用的芯片进行选择;在Target interface选项 里面选择SWD模式;首先Target里面选“Connection”连接目标芯片,然后 Target--Auto进行程序烧写;首先Target里面选择“Connection”连接目标芯片,然后 Target--Auto进行程序烧写.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

  • 半导体制冷温度控制系统的设计研究

    在半导体制冷技术的工作性能及其优缺点研究的基础上,设计了以单片机为核心控制元件,以TEC1-12706为执行元件的半导体制冷温度控制系统。采用高精度分段式PID控制算法配合PWM输出控制的方法实现温度控制;选择数字传感器DS18B20为温度检测元件,还包含1602液晶显示模块、按键调整输入模块和H桥驱动模块等。实际测试表明,该系统结构简单易行,操作方便,工作性能优良,同时针对该系统专门设计的温控算法,使半导体制冷器能更好地适应不同工况而充分发挥其制冷制热工作特性。Based on the study of the performance and advantages and disadvantages of thermoelectric cooler(TEC)technology,a thermoelectric cooling temperature control system with single-chip microcomputer as the core control element and TEC1-12706 as the executive element was designed. High precision piecewise PID control algorithm combined with PWM output control method is adopted to realize temperature control. The digital sensor DS18B20 is selected as the temperature detection element. It also includes 1602 LCD module,key adjustment input module and H bridge drive module. The actual test shows that the system has simple structure,convenient operation and excellent performance. Meanwhile,the temperature control algorithm specially designed for the system can make the semiconductor cooler better adapt to different working conditions and give full play to its refrigeration and heating characteristics.

  • 步进电机驱动器原理图+PCB+驱动源码+使用教程等

    该步进电机驱动器又称为EasyDriver,EasyDriver能够为两级步进电机提供大约每相750mA(两极一共1.5A)的驱动。它默认设置为8步细分模式(所以如果你的电机是每圈200步,你使用EasyDriver时默认为每圈1600步),更多细分模式可以通过将MS1或MS2两个接脚接地进行设置。这是一种基于Allegro A3967驱动芯片的细分断路器。对于此设计的完整规格,请查阅A3967的参数表。它的最大每相电流从150mA到750mA。可以采用的最大驱动电压大概是30V,其中包括板载5V的调压器,所以只需要一个电源。质优价廉,这玩意儿只要十几美元,比你自己制作电路板更便宜。步进电机驱动器设计特色:· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
