Read GPIO Status

Reads the state of a [GPIO] pin http://pt.wikipedia.org/wiki/General_Purpose_Input/Output specified by the gpio parameter. The HTTP method used is POST.

POST /gpio_state.fcgi

Parameters

• gpio (int): Number of the general-purpose pin (GPIO) whose state you want to read.

For iDFit/iDAccess:

• pin 0 - alarm zone 1
• pin 1 - alarm zone 2
• pin 2 - alarm zone 3
• pin 3 - alarm zone 4
• pin 4 - alarm zone 5
• pin 5 - Door sensor 1
• pin 6 - Door sensor 2
• pin 7 - button 1
• pin 8 - button 2
• pin 9 - alarm output
• pin 10 - LED of Biometry
• pin 11 - Relay 1
• pin 12 - Relay 2
• pin 13 - Tamper sensor
• pin 20 - Wiegand output 1
• pin 21 - Wiegand output 0
• pin 22 - Wiegand input 1
• pin 23 - Wiegand input 0

For iDFlex/iDAccess Pro/iDAccess Nano:

• pin 0 - Tamper sensor

For iDFace:

• pin 0 - Tamper sensor
• pin 1 - SIP call button

Response

• enabled (int): Indicates whether the GPIO is enabled (1) or disabled (0). An attempt to read or write to a disabled GPIO has an indefinite effect.
• in (int): Indicates whether the GPIO is configured as input pin (1) or output pin (0).
• pin (string): Contains the name of the GPIO.
• idle (int): Contains the value of the GPIO when idle.
• pullup (int): Indicates whether GPIO pullup is enabled (1) or disabled (0).
• value (int): Contains the current GPIO value.
• notify (int): Indicates whether the access software will be warned (1) of changes to this GPIO or not (0).
• notified (int) : Indicates how many times the GPIO has notified the access software of a change.

Request Example

Reading the state of GPIO 1:

    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify({
        gpio: 1
    })
});
