AURIX平台实现PWM触发ADC采样,顺序采样(aurix complete pwm trigger function)

利用单片机（STC89C52）为核心结合机械按键、数码管以及稳压器件等电子元器件组装了一个数字时钟，可以实现精准的计时以及修改等功能；(The combination of mechanical buttons, digital tube, and electronic regulator device the microcontroller (STC89C52) as the core components assembled a digital clock, and can achieve precise timing and modify functions )

基于51的C语言频率计，内涵仿真图，以实现空能(Based on 51 C-language frequency meter, meaning simulation diagram, in order to achieve air can)

18B20电路图,温度传感器，汇编版与C语言版共有及51开发板上的连线(The 18B20 schematic, temperature sensor, assembly version of the C language version of Total and 51 development board of the connection)

基于stm32单闭环pid调速控制，单电阻采样，正弦波驱动，pid调速。(Based on stm32 pmsm drive, single sampling resistor, sine wave drive, pid speed control.)

测试电脑鼠各个红外探测器的算法，可自行调试(Test each computer mouse infrared detector algorithm, self-debugging)

这是基于单片机的计算器程序，可以实现加减乘除的功能(This is based on single-chip calculator program, Math functions can be achieved)

说明：  采用4路红外对管进行循迹，电机控制小车运动。(Four infrared channels are used to track the tube, and the motor controls the motion of the car.)

内核重载过TP（看雪大牛作品，非常完整）(Kernel overloaded over TP (see snow Daniel works very complete))
