ST单片机的LIN总线通信代码。详细说明，范例，库。Description of STM8 LIN software package (STSW-STM8A-LIN) release 5.1(Description of STM8 LIN software package (STSW-STM8A-LIN) release 5.1)

说明：  针对温度控制系统，采用传统pid和模糊pid，进行比较，用模糊控制器实时调节pid参数以实现较好的效果(For the temperature control system, the traditional pid and fuzzy pid are used for comparison, and the fuzzy controller is used to adjust the pid parameter in real time to achieve better results.)

pic16f1829的i2c通信.一个pic做从机另一个做主机，主从都是硬件操作没有用软件模拟。主机发送一个值用于调整从机的pwm。(I2C communication pic16f1829. A pic from another host, master and slave are hardware operation without the use of simulation software.The host sends a value used to adjust from the machine pwm.)

使用keil5编写的STM32输出四路互补的PWM，适配正点原子的mini版，同样是为电赛逆变系统做的准备。通过定时器的输出比较模式，在PC6~PC9，输出4路PWM，每路PWM频率为500Hz，占空比为50%，每一路PWM相位差为45°(The STM32 output four complementary PWM, which is written in keil5, is suitable for the mini version of the positive point atom, which is also the preparation for the electric match inverter system.Through the output comparison mode of the timer, in PC6~PC9, the output 4 road PWM, the PWM frequency of each road is 500Hz, the duty ratio is 50%, and the PWM phase difference of each road is 45 degrees.)
