实现呼吸灯的功能，用两种不同的方法。基于stm32f103，可给初学者一个较好的编程思路(To achieve the function of the breathing lamp, use two different methods. Based on stm32f103, it can give beginners a better programming idea)

说明：  一本较好的VB教程，主讲上位机编程，相信大家会喜欢的。(A better VB tutorials, keynote host computer programming, I believe you will like.)

说明：  用于arduino单片机驱动错误的修复。如电脑无法识别。或被电脑识别为usb设别而非串口。(t is used to repair driving errors of Arduino single chip computer. If the computer can not recognize. Or it can be recognized as a USB device rather than a serial port by a computer.)

LED显示屏的设计可以实现动态字体的左移右移上下移动等功能(LED display is designed to realize the right to move to the left and so on down the function of dynamic fonts)

串口控制c源代码，自己看看，根据例程改的(Serial port control C source code)

说明：  modbus仿真设计，充当服务器的功能，在测试中具有很重要作用(Modbus simulation designed to serve as a server.It plays an important role in testing.)

用控制台程序倒着输出九九乘法表；输出结果按下图所示： 1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81 …… 1*3=3 2*3=6 3*3=9 1*2=2 2*2=4 1*1=1 ( 1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81 …… 1*3=3 2*3=6 3*3=9 1*2=2 2*2=4 1*1=1 )

TI公司的ADS1299是8路低噪音同时取样的24位delta-sigma ADC,并内置了可编程增益放大器(PGA),基准电压和振荡器,集成了脑电图(EEG)所需的通用特性.器件具有非常低的输入参考噪音:1.0 μVPP (70-Hz BW),没路的功耗5mW,输入偏置电流300pA,数据速率250SPS到16kSPS,C1.0 μVPP (70-Hz BW),CMMR为-110dB,可编程增益为1, 2, 4, 6, 8, 12或24,单极或双极电源工作,主要用在医疗仪器如EEG和ECG,听觉诱发电位(EAP),脑电双频谱指数(BIS),睡眠研究监测等,高精度多路信号采集.(The ADS1299 is a low-noise, multichannel, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADS1299 incorporates all commonly-required features for electroencephalogram (EEG) applications.)

oled屏幕上面显示时分秒，可自行控制暂停(Time and seconds are displayed on the OLED screen, and the pause can be controlled by itself.)

主要是基于STM32的音乐喷泉调试程序，采样音频信号进行FFT变换，再输出PWM波控制电机出水。(Mainly musical fountain debugger STM32-based sampling FFT transform audio signals, and then outputs PWM wave to control the motor water.)
