STM32 的定时器能功，可以用来作为信号发生器和频率计，一方面来测频，一方面来发生频率可变，占空比可变的信号发生器(STM32 timer can work, can be used as a signal generator and frequency meter, on the one hand to measure frequency, on the one hand to variable frequency, duty cycle variable signal generator)

stm32为核心的全套信号发生器代码《电子设计》，内涵论文及源代码(stm32hajsbhasfasagasdzasfaf)

stm32使用TIM+DAC+DMA输出任意波形,实现简单的信号发生器(STM32 uses TIM+DAC+DMA to output arbitrary waveform to realize simple signal generator)
