8.9.2. Set the output value of a GPIO pin
Command format: SET●/MEDIA/GPIO/P
n
.Output=<value>
Response format: pw●/MEDIA/GPIO/ P
n
.Output=<value>
Legend: <value>: value of the GPIO pin: H=high level; O=low level
Example:
˃ SET /MEDIA/GPIO/P1.Output
˂ pw /MEDIA/GPIO/P1.Output=H
8.9.3. Toggle the value of a GPIO pin
Command format: CALL●/MEDIA/GPIO/P
n
:toggle(1)
Response format: pw●/MEDIA/GPIO/ P
n
:toggle
˃ CALL●/MEDIA/GPIO/P1:toggle(1)
˂ mO●/MEDIA/GPIO/P1:toggle
