GPIO properties¶

Below are the available gpio properties are described. To each gpio needs to be accessed by their Property followed by the target in or output [ ] square brackets

gpio.input.function[1] = gpio.input.function.talk 

// sets the function of the first GPI to talk

gpio.input.function¶

Property for GPI input function. needs to be called with an [index] and can be assigned with one of its values.

gpio.input.value¶

Property for GPI input channel. needs to be called with an [index] and can be assigned with any of the available regular channels. By default 1 - 32, and 24 added for each connected extension.

gpio.input.normally¶

Property for GPI normal state. needs to be called with an [index] and can be assigned with one of its values.

gpio.input¶

Property to read the current GPI state. needs to be called with an [index] and has one of its values.

gpio.output.function¶

Property for GPO function. needs to be called with an [index] and can be assigned with one of its values.

gpio.output.value¶

Property for GPI output channel. needs to be called with an [index] and can be assigned with any of the available regular channels. By default 1 - 32, and 24 added for each connected extension.

gpio.output.normally¶

Property for GPO normal state. needs to be called with an [index] and can be assigned with one of its values.

gpio.output¶

Property to override the current GPO state needs to be called with an [index] and can be assigned one of its values

Beacon GPI¶

gpi.bcn¶

property for the GPI inputs on the USB data pair connection of the beacon. needs to be addressed with the index of the gpi in [] square brackets, can be 1 or 2 or with the predefined values

the value of a GPI can be read and can have the following values.

a closed contact is switched to the USB ground

event gpi.bcn[gpi.bcn.2]
    if gpi.bcn[gpi.bcn.2] == gpi.bcn.closed
        // action if contact is closed
    else   
        // action if contact is opened
    end
end
