STM32运用PID控制DA输出电压稳定，可以设置。(STM32 using PID control DA output voltage stability, can be set.)

说明：  keil c51 开发安装包 新唐51内核插件(Keil C51 Development and Installation Package Xintang 51 Kernel Plug-in)

说明：  sht20温度湿度读取源码,C语言源码，自测成功，STM32平台(read the sht20, and show the temp and hum.)

说明：  能够驱动5v-12v直流电机电动小车的驱动不但要求电机驱动系统具有高转矩重量比、宽调速范围、 高可靠性，而且电机的转矩 -转速特性受电源功率的影响，这就要求驱动 具有尽可能宽的高效率区。(The drive of 5V-12V DC motor electric car requires not only the motor drive system with high torque-weight ratio, wide speed range and high reliability, but also the torque-speed characteristics of the motor affected by power supply power, which requires the drive to have as wide a high efficiency area as possible.)
