Chengdu Ebyte Electronic Technology Co., Ltd.
start/stop: Start/stop channel PWM output
0xFF means to start PWM in 1mS unit, the parameter range is 0-340, and the maximum period that can be set
is 340mS. When the period parameter is less than 2, the period parameter is 2, and the period is 2mS (2*1mS ).
0xFE means to start PWM in 0.5uS unit, the parameter range is 0-3400, and the maximum period that can be
set is 1700uS (3400*0.5 ). When the period parameter is less than 2, the period parameter is 2, and the period is 1uS
(2*0.5uS).
0x00 means stop PWM.
Period: Cycle time of PWM (the unit of cycle and the maximum cycle are determined according to the start/stop byte)
Period1 indicates the upper 8 bits
Period2 indicates the lower 8 bits
Duty: Duty cycle time of PWM (the unit of cycle and the maximum cycle are determined according to the start/stop byte)
Duty1 indicates the upper 8 bits
Duty2 indicates the lower 8 bits
Note:
1. The value of period must be greater than the value of duty. It is recommended that the difference between period and
duty is greater than 2ms. If the period is less than duty, the system will default that period is equal to twice of duty. The
duty here represents the high level time.
2. The PWM cycle units of the four channels need to be the same.

For example, value read: voltage =0x0C
Then voltage is: voltage =0x0CE4
No:
1. If the power supply voltage is the highest 3.3V, the detection range of ADC can reach 3.3V.
2. The time interval between two times of reading of ADC voltage of the same device must be greater than 10ms.
