Pwm peripheral configuration data format (6 Byte): PwmId start/stop Period1 Period2 duty1 duty2
PwmId: Channel ID
start/stop: start and stop channel PWM output
0xFF means to start PWM in the unit of 1mS, the parameter range is 0-1700, and the maximum period that can be set is
1700mS.
0xFE means to start PWM with 1uS as the unit, and the parameter range is 0-1700, then the maximum period that can be
set is 1700uS.
0x00 means stop PWM
period: pwm cycle time (determine the unit of the cycle and the maximum cycle according to the start/stop byte)
Period1 represents the upper 8 bits of the period
Period2 means that the lower 8 of the period is
duty: pwm duty cycle time (according to the start/stop byte to determine the cycle unit and the maximum cycle)
