51单片机LED流星雨灯，原理： 利用PWM来模似流星雨：将亮度等级分为8个 ，通过改变每一组LED的亮度来达到流星雨效果。因为流星雨是前面亮后面越来越暗，就像一条龙一样，拖着尾巴过来。(51 single LED meteor light, principle: the use PWM to die like a meteor shower: The brightness level is divided into eight, each group by changing the brightness of the LED to achieve the effect of the meteor shower. Because meteor shower is getting back in front of bright dark, like one-stop, like dragging tail over.)

求解二维声子晶体能带结构XY模式，内附注释，希望能帮到你(Solving the two-dimensional phononic crystal band structure XY mode, included comments, I hope it may give some help )

在keil中，用程序控制stm32的声卡，程序较为简洁高效！(In keil, the use of the program to control the STM32 sound card, the program is relatively simple and efficient!)

stm32下使用max7219驱动点阵,使用spi总线来没驱动，最后下载验证，结果很稳定。(Under the stm32 use max7219 driver lattice, the use of spi bus to not drive, download the verification, the result is stable.)

这是基于STM32的USART转232的应用程序(This is based on the STM32 USART 232 applications)

说明：  这是我认为51汇编里面比较好理解的书籍，以及我简单整理的汇编指令文档一份。入门学习还是不错的。(This is a book that I think is better understood in the 51 assembly, as well as a document of assembly instructions that I simply organized. Initial study is still good.)
