本例展示了如何利用外设TIM2来产生四路频率不同的信号。
TIM2时钟设置为36MHz，预分频设置为2，使用输出比较-翻转模式（Output Compare Toggle Mode）。
TIM2计数器时钟可表达为：TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz
设置TIM2_CCR1寄存器值为32768，则CC1更新频率为TIM2计数器时钟频率除以CCR1寄存器值，为366.2 Hz。因此，TIM2通道1可产生一个频率为183.1 Hz的周期信号。
同理，根据寄存器TIM2_CCR2 、TIM2_CCR3和 TIM2_CCR4的值，TIM2通道2可产生一个频率为366.3 Hz的周期信号；TIM2通道3可产生一个频率为732.4 Hz的周期信号；TIM2通道4可产生一个频率为1464.8 Hz的周期信号。
可以通过示波器观察各路输出-This example demonstrates how to use peripherals TIM2 to generate four different signal frequencies. TIM2 clock set to 36MHz, pre-divider is set to 2, the use of output compare- flip model (Output Compare Toggle Mode). TIM2 counter clock can be expressed as: TIM2 counter clock = TIMxCLK/(Prescaler+ 1) = 12 MHz set TIM2_CCR1 register value is 32768, then cC1 update frequency for TIM2 counter clock frequency divided by the value of CCR1 register for 366.2 Hz. Therefore, TIM2 channel 1 can generate a frequency of 183.1 Hz for the periodic signal. Similarly, under the register TIM2_CCR2, TIM2_CCR3 and TIM2_CCR4 value, TIM2 channel 2 can have a frequency of 366.3 Hz cycle signal TIM2 channel 3 can have a frequency of 732.4 Hz cycle signal TIM2 Channel 4 can produce a frequency of 1464.8 Hz cycle signal. Can be observed through the oscilloscope various output
