The new LabVIEW navX-AE software library and example code integrates navX-sensors into a RoboRIO Robot. LabVIEW navX-AE supports access to navX2-MXP via SPI, USB, I2C and TTL UART, and to navX2-Micro via I2C.
Note that the navX-AE library is also backwards-compatible with the “Classic” navX-MXP and navX-Micro sensors.
[Update: 1/12/2021 – Version 4.0.412 is now available – which is compatible with the FRC 2021.1.2 (Kickoff) Release. This is compatible with the 2020 FRC Release of LabVIEW.]
After running the setup program included in the latest build, the navX AE library will be located in the LabVIEW tool palette, in the WPI Robotics Library->Sensors->ThirdParty palette menu.
To begin using LabVIEW navX-AE, locate the navX Main.vi in the navX AE Tool Palette then drag and drop the navX Main.vi onto your main block diagram (alternatively, you can place navX Main.vi in the timed tasks vi). Important NOTE: DO NOT PLACE navX Main.vi in a loop.
Once placed on the block diagram, navX Main.vi will initialize communications with the navX2-sensor. After placing navX Main.vi on the block diagram, use the protocol selector to choose the communication protocal that you want to use. Choices include SPI, I2C, TTL UART, and USB.
Reading sensor data
After configuring navX Main.vi, sensor data can be retrieved from the connected navX-sensor. Available sensor data is accessible via the various navX-AE “Get” vis on the “Get” Tool Palette.
Modifying sensor configuration
In addition to retrieving sensor data, certain actions (such as zeroing the yaw) are available via the navX AE “Set” vis on the “Set” Tool Palette.
After getting the sample navX-sensor application running, please see the Examples section for a description and sample code which implements some key capabilities enabled by navX-sensors.
