跑马灯设计，主要是利用51单片机完成跑马灯的设计(Marquee design)

模拟了现实中的示波器，可以滚动显示波形，动态显示，属性振幅都可以改变 实用性 比较好 (Simulated reality oscilloscope, you can scroll waveform display, dynamic display, amplitude attribute can be changed relatively good practicality)

基于MSP430G2553 TI超低功耗单片机，5110液晶显示程序(Based MSP430G2553 TI ultra-low power microcontroller, 5110 LCD procedures)

状态机按键检测，实现单击双击多击功能,单片机用的是STM8L(Key detection state machine to achieve multi-click-click, double-click function)

模拟PWM信号控制小灯，控制二极管占空比(Analog PWM signal control light)

说明：  单片机c语言 初学者有用 有例子哦 (SCM c language for beginners there are examples of useful oh)

AD9851驱动程序，采用串行写入方式，STM32写入频率控制字。(AD9851 driver, using serial write mode, STM32 write frequency control word.)

ACR38智能读卡器测试用：芯片IC卡等(ACR38 Smart Card Reader test: IC card, etc.)

ht1621的液晶驱动程序，很好用，欢迎下载。(ht16xx LCD driver, useful, welcome to download. A password to extract passwords note that the procedures do not have the passwords.)
