Description:
1. Be effective at once, save when power off.
2. 4 PWM output frequencies are identical.
PWM Period calculating method description:
Assuming that the required target cycle is t ,and the input parameter is para (i.e. "AT+PWMFRQ=para"), then
t=T*para,means para=t/T.
For example, the setting cycle is 5ms: then para=5ms/0.01ms=500.
