1.It takes effect immediately, save when power off.
2.4-way PWM output frequencies can be different.

6.44 Set and query PWM duty cycle

Command
Query：AT+DUTYx?
Setting：AT+ DUTYx =[para]
Description:
1.It takes effect immediately, save when power off.
2.4-way PWM output frequencies can be different, and the duty cycle can also be different.

6.45 Query ADC sampling value

Command
Query：AT+ADCx?
Setting：AT+ ADCx =[para]
Description: 12-bit ADC acquisition, output displays in decimal

6.46 Set and read the maximum battery voltage

Command
Query：AT+ BATMAX?
Setting：AT+BATMAX=[para]
Description: Set according to the full voltage of the battery
Because the working voltage of the chip is limited to 1.8V ~ 3.8V, the maximum BATMAX is 3800.

6.47 Set and query the minimum battery voltage

Command
Query：AT+ BATMIN?
Setting：AT+BATMIN=[para]
