Note
This Bricklet is currently in the prototype stage and the software/hardware as well as the documentation is in an incomplete state.
This is the description of the Shell API bindings for the Analog Out Bricklet 2.0. General information and technical specifications for the Analog Out Bricklet 2.0 are summarized in its hardware description.
An installation guide for the Shell API bindings is part of their general description.
The example code below is Public Domain (CC0 1.0).
1 2 3 4 5 6 7 8 | #!/bin/sh
# connects to localhost:4223 by default, use --host and --port to change it
# change to your UID
uid=XYZ
# set a voltage of 3.3V
tinkerforge call analog-out-v2-bricklet $uid set-output-voltage 3300

Possible exit codes for all tinkerforge commands are:
The common options of the call and dispatch commands are documented here. The specific command structure is shown below.
Parameters: |

---|
The call command is used to call a function of the Analog Out Bricklet 2.0. It can take several options:
Parameters: |
|
---|
The dispatch command is used to dispatch a callback of the Analog Out Bricklet 2.0. It can take several options:
Parameters: |
|
---|
The <function> to be called can take different options depending of its kind. All functions can take the following options:
Getter functions can take the following options:
Setter functions can take the following options:
The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is send and errors are silently ignored, because they cannot be detected.
