Adjustment for duty cycle value Range of 0~222222 corresponding to 0ms~10ms (high level time≈value*45ns)
3
Channel number range 1~4 indicates the number of currently enabled PWM channels, increasing from PWM0,
for example channel number is equal to 2, then PWM0 and PWM1 are enabled(channel number cannot be
changed after the first transmission)
Notes
1
The actual duty cycle = adjustment value for duty cycle *45ns/ cycle
The following figure shows the cycle for opening four channel is 10ms, the duty cycle is 50% for PWM.
2
Calling PWM command once again to modify the duty cycle.
Click “PWM output” after parameter-setting (AT+EBPWM=4, 10000, 111111, 111111, 111111, 111111).
（
Please refer to the AT chapter for AT command
）
Click “PWM output” one more time after parameter-setting to modify PWM output.
But channel number cannot be changed after the first setting.
Channel number after modifying other parameters must keep the same as the first set, otherwise the error is returned.
Notes: PWM channel cannot be closed after opening. It can be reset by reset command or re-power.
