用L298作为驱动器，控制两相混合式步进电机。 按键从上至下分别为减速，加速，正转，反转，停止。 具体参数还没有设定过。速度有些慢，加速按2下有效，然后就不能再快了。 转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.

随着精准农业的发展，农业种植和农业研究人员需要一种手持式NDVI测量仪，以便对农作物长势进行定量测量。本文讨论了一种手持式NDVI测量仪的完整设计过程，详细论述了设计原理，并给出了详尽的单片机程序、设计电路原理图及PCB图。该NDVI测量仪采用太阳光作为光源，光电探测器采用滤光片和光敏二极管实现，用AT89C51单片机控制。其具有结构简单、成本低、轻便、低功耗的特点。-With the development of precision agriculture and farming, and agricultural researchers need a handheld NDVI measuring instrument, in order to crop growth for quantitative measurement. This paper discusses a handheld meter NDVI the integrity of the design process, discussed in detail the design principles, and gives a detailed SCM procedures, circuit schematics and PCB plans. The NDVI measuring instrument used sunlight as a light source, photodetector using filters and photodiode realized, with AT89C51 control. Its structure is simple, low cost, lightweight, low-power characteristics.
