说明：  基于STM32F407 MCU，对RS485进行通讯测试,DMA收发数据，经测试数据稳定，功能正常(Based on STM32F407 MCU, RS485 was tested for communication,DMA data receiving and receiving, the tested data was stable and the function was normal)

说明：  无刷电机驱动器源代码。基于无传感器方案的无刷电机启动器。核心是换向角度检测：即电机反电势波形数据处理，经过衰减滤波，取出过零相位。应为低速反电势波形dB过小，波形扰动太大，本程序还不能稳定处理10Hz以下的换向计算。(Brushless motor driver source code. Program based on the sensorless brushless motor starter. Is the core to the point of view for detection: the motor back-EMF waveform data processing, through the attenuation filter, remove the zero-crossing phase. For low-speed back-EMF waveform dB is too small, waveform disturbance too, this procedure can not be stabilized to 10Hz for the following calculation.)

Silicon Crystallization Simulation CRYSTAL is a program used to simulate the process of creating a crystal of silicon for use in creating computer chips.

GD32 SPI 主从通信，通过片选IO启动传输，单次最大传输64K(GD32 SPI master-slave communication)

该例程是利用MC9S12DG128中TC0和TC7通道共同完成模拟PWM功能的实例。(The routine is the use of MC9S12DG128 the TC0 and TC7 simulated co-channel PWM function instance.)

最近几天突然对红外线遥控器发生兴趣，于是上网混了一下，发现编码方式有好几种，而且同一种编码方式又有许多不同的细节，为了弄清楚手头的遥控器是出身何门，无奈手头又没有logic分析器之类可望不可及（广东话里“及”同“望”都系“睇”既意思）的东西，遂萌生了写这个软件的冲动。(Infrared logic analyzer )
