PWM模式也叫脉冲宽度调制模式，它可以产生一个频率和占空比可调的方波。由TIMx_ARR寄存器确定频率、由TIMx_CCRx寄存器确定占空比的信号。在硬件电路中，PWM波产生通常是由一个三角波和参考值送入比较器中，然后比较器输出的就是PWM波。 V1是三角波发生器 ...

Say, we wish to configure AF mode on an STM32F103 MCU, first we look in its reference manual (RM0008) at section 9.3 (‘Alternate function I/O and debug configuration (AFIO)’) and zip over to ...
