Arduino 开发板上用的PS2接口鼠标源码(Arduino PS2mice)

使用定时器TIM3输出四路的SPWM波，其中一二路、三四路波形一致，一二路与三四路波形相差180°(Timer TIM3 is used to output four SPWM waveforms, of which one, two, three and four waveforms are identical, and one, two and three and four waveforms are 180 degrees different.)

NRF51822相关的API相关的代码，不是很完整，希望有帮助(NRF51822 related API related code, not very complete, I hope to help)

该程序为自己做的一个项目：精准控温，控温精度正负1度。温控最高可达200度。其中运用了usb虚拟串口、AD采集、Time1中断等.(The program is a project to do: precise temperature control, temperature control accuracy of plus or minus 1 degrees. The temperature up to 200 degrees. The use of USB virtual serial port, AD acquisition, Time1 interrupt.)

STM32的ADC程序，亲测可用。内有详细注释和说明文档，很好的参考资料。(STM32 ADC program, pro - test available. There are detailed notes and documentation, good references.)

说明：  一种新型模糊自适应PID的控制算法，试验证明是很有效的(A new type of fuzzy adaptive PID control algorithm, the pilot proved to be very effective)

用单片机仿真的一个定时器,很有意思,里面有仿真文件,可以瞧瞧(Single-chip simulation using a timer, it is interesting, there are simulation file, you can look at)
