7 AT command
Only list some special AT command for your reference, more AT command please refer to the official datasheet.
1
AT+EBPWM-PWM Set or modify
T+EBPWM=<channel_num>,<period>,<duty0>[,<du
ty1>][,<duty2>][,<duty3>]
Parameter specification
：
channel_num
：
channel number
period
：
cycle
（
1000~10000corresponding
to1~10ms
）
duty0~duty3
：
PWM0~PWM3Duty cycle setting
（
high level time=duty*45ns
）
Duty number should keep the same with channel
number.
Response:
First transmission response
：
PWM Start!
Non-first transmission response
：
OK
Error response
：
ERROR
Example: Set PWM0 duty cycle 25% PWM1 duty cycle 50% cycle 10ms
AT+EBPWM=2,10000,55555,111111
Notes
：
PWM cannot be closed after booting, and channel number cannot be modified.
2
AT+EBIOGET to get IO input status
AT+EBIOGET=<gpio_num>
Parameter specification
：
gpio_num
：
GPIO number, 4,5,12,13 and 14 are
available.
Response
：
0 or 1
OK
Example
：
AT+EBIOGET=4
Notes
：
The pins which could been used to be the PWM output, is not suitable for this command.
3
AT+EBIOSET to configure IO output status
AT+EBIOSET=<gpio_num>
，
<value>
Parameter specification
：
gpio_num
：
GPIO number, 4,5,12,13 and 14 are
available.
Value: Pin status can be configure to 0,1
Response
：
OK
Example
：
AT+EBIOSET=4
，
1
Notes
：
The pins which could been used to be the PWM output, is not suitable for this command.
4
AT+EBADC to get ADC value
AT+EBADC
Parameter specification
：
Range of input voltage
：

Response
：
45
（
real voltage=45/1024
）
OK
Example
：
AT+EBADC
5
AT+EBSTATE register GPIO13 as Wi-Fi indicator
