Inputs

Inputs are assets that push signals to the Octave-enabled device at some arbitrary time and interval. You will create an input resource in Octave any time you have an asset connected to the Octave-enabled device that you want to monitor in Octave.

Note

If the asset does not push data to the Octave-enabled device, then you must use a sensor instead, to poll for the data from Octave.

The following steps describe how to add and configure an input resource in Octave that is connected to a GPIO pin.

Configuring an Input

Inputs such as GPIO input pins, must be configured on the Device > Services screen. Follow the steps below to add a new GPIO input pin:

1. Navigate to Device > Services (1), locate the GPIO section (2), and click Configure (3).

2. Locate the Add pin (1) section.

3. Click the Pin (1) drop down and select a GPIO pin (e.g. WP_GPIO_1).
4. If the input supports both input and output signals, ensure that Input (1) is selected for the pin. Note that the Input field (1) is automatically selected and set to read-only when the selected pin only supports one direction.

5. (Optional) Set the Resource field (2) to a more descriptive name. By default, the Resource created by the IO service will share the name of the pin that it connects. However, it's usually much more practical to use a short name that describes what you are actually connecting. For example, red_led might make sense for a digital output connected to an LED, while photoresistor might make sense for an analog input name.
6. Click Add (3) to add the input to the list. Note that the path provided in the previous step has been prepended with /io.
