stm32f7采集一遍往外打点一遍用AD采点然后将采样值返回给电脑(Stm32f7 collects points from outside once, uses AD to collect points, and then returns the sampled values to the computer.)

Zwicker响度计算公式，ISO 532B(Zwicker loudness calculation formula, ISO 532B)

说明：  ALIENTEK STM32开发板SYSTEM文件夹，采用V3.5库的头文件，使得代码可以完美移植到库函数里面使用，不过注意，在新建工程的时候，请在：Options for Target-->C/C++ 选项卡里面 Preprocessor Symbols 栏定义你的STM32芯片容量。比如:ALIENTEK 战舰STM32开发板用户，使用的是大容量的STM32芯片，则在Define栏输入：STM32F10X_HD 对于STM32F103系列芯片，设置原则如下： 16KB≤FLASH≤32KB 选择：STM32F10X_LD 64KB≤FLASH≤128KB 选择：STM32F10X_MD 256KB≤FLASH≤512KB 选择：STM32F10X_HD(ALIENTEK STM32 development board SYSTEM folder, using V3.5 library header file, so that code can be perfectly transplanted to the library function to use, but note that in the new project, please: Options for Target - > C/C++ tab in the Preprocessor Symbols column to define your STM32 chip capacity. For example: ALIENTEK warship STM32 development board users, using a large capacity STM32 chip, in the Define column input: STM32F10X_HD For STM32F103 series chips, the setting principles are as follows: 16KB < FLASH < 32KB Selection: STM32F10X_LD 64KB < FLASH < 128KB Selection: STM32F10X_MD 256KB < FLASH < 512KB Selection: STM32F10X_HD)

说明：  Arduino 对接收到的信号进行解码操作，从而得到按键信息，根据按键值控制舵机。(By decoding the received signal, the key information is obtained and the steering gear is controlled according to the key value.)

基于LPC1768重复定时器实现的数字钟实例，利用其重复定时器实现一个数字钟功能(Based on LPC1768 repeated instances of digital clock timer, and use a timer, repeated digital clock function)

基于51单片机两相四线步进电机驱动程序，本程序可用42，57系列步进电机，工作方式为八拍。(Based on 51 single-chip two phase four line stepping motor driver, this program can use 42, 57 series of stepper motor, working mode is eight.)
