输入字符串 生成相应的CRC16-modbus校验码(create the crc16-modbus checkcode depends on the charactor string input to the program)

STM32HAL 库，USB HOST，介绍，可以了解。(STM32HAL library, USB HOST, introduction, you can understand.)

这是一个QPSK的调制及解调过程的例子，供大家学习参考(This is the example of a QPSK modulation and demodulation process for them to learn from the reference)

说明：  按照洛伦兹分布将散点拟合成曲线，基于Labview(Lorentz distribution curves fiting based on Labview.)

A计权是分析声学信号在计算声压级的时候必须做的一个步骤，程序里解释了A计权的方法。(A weight is a step in the analysis of acoustic signals must be done in the calculation of sound pressure level, the program explained A right.)

说明：  基于LabVIEW的电机控制系统。包括：直流电机闭环，永磁同步电机控制，电机转速调试，步进电机控制，电机调速器等。适合相关从业人员交流学习。(The motor control system based on LabVIEW. Including: DC motor closed-loop, permanent magnet synchronous motor control, motor speed debugging, stepper motor control, motor governor, etc. It is suitable for relevant practitioners to exchange and study.)

说明：  labview学习资料，花了2W获得的过程学习资料，可以看看很多小例程，值得学习！(LabVIEW learning materials, spent 2W to get the process of learning materials, you can see a lot of small routines, worth learning!)

用于测量信号的振幅谱与功率谱，对初学LABVIEW做信号分析会有帮助。(Used to measure the signal amplitude spectrum and the power spectrum, signal analysis for beginners LABVIEW do help.)

函数发生器，各种常规的波形发生，以及数据的存储和数据导入功能！(Function generator, a variety of conventional waveform generation, and data storage and data import capabilities!)

Labview基础练习以及几种简单数字门电路、触发器、译码器等的实现(Labview-based exercises and some simple digital gates, flip-flops, such as the realization of the decoder)
