说明： 本例程实现功能：
通过定时器3的输出比较模式，在PC6~PC9，输出4路PWM，每路PWM频率为500Hz，占空比为50%，每一路PWM相位差为45°
通道1接的是PC6，通道2接的是PC7，可以看到他们的时间差是250us，一个周期是2ms（500Hz），刚好是1/8个周期，即45°。符合设计要求。
在此基础上，大家只需要稍作修改，即可实现其他相位差的波形输出。
(This routine realizes the following functions
Through the output comparison mode of timer 3 four PWM channels are output from PC6 to pC9 with each PWM frequency of 500Hz, duty cycle of 50, and phase difference of each PWM channel of 45
Channel 1 is connected with PC6 and channel 2 is connected with PC7. We can see that the time difference between them is 250us. One cycle is 2ms 500Hz which is exactly 0.125 . Meet the design requirements.
On this basis, we only need a little modification to achieve other phase difference waveform output.)
