ANNOUNCING: Kauai Labs navX-MXP Upgrade, navX-Micro & SF2

[naldarn]

The Labview information is difficult to find, http://www.pdocs.kauailabs.com/navx-mxp/labview-ae/

has nothing on it.

and if you go to the navx-micro for the examples, it takes you to github and shows you the c++ examples instead of Labview.

Thanks for the head's up; the path to the labview AE URL is fixed.

As far as the navX-Micro examples, you likely found yourself to the FTC examples; there are separate FRC examples linked to as well on the navX-Micro Examples page.

I am getting a navXFirmware error "unable to load DLL 'STDFUFiles.DLL' on 2 different laptops with the firmware downloaded on each laptop (not copied from USB). Can anyone please help?

Thanks in advance,

Mr. B

Is there any plan to port SF2 to Python? If there are not any official plans, I'll probably try in my free time (hah!)

We don't have this in the plans right now (we're focused on developing other very cool SF2 features). However, you might contact Dustin Spicuzza, he's done some amazing work to port the navX-MXP libraries to Python. And I'd be happy to provide support if you should choose to attempt this yourself.

Aloha,

Are there any FRC Java examples for turning to or driving on a heading with a tank drive like there are for FTC? The FRC examples all seem to be for a mecanum drive. Thanks!

Hi, after installing the latest navx_mxp jar file we are getting the following errors during deploy. We followed the Java coding steps from the Kauai Labs website. Any suggestions would be welcomed.

Thanks in advance.

[javac] RobotMap.java:3: error: package com.kauailabs.navx.frc does not exist
[javac] import com.kauailabs.navx.frc.AHRS;
[javac] ^
[javac] RobotMap.java:23: error: cannot find symbol
[javac] AHRS x = new AHRS(SerialPort.Port.kMXP);
[javac] ^

[javac] AHRS x = new AHRS(SerialPort.Port.kMXP);

The info you sent suggests that Eclipse can't locate the navx_frc.jar file (the navX-MXP RoboRIO Java Library).

For 2017, the location of the navX-MXP RoboRIO Java Library has changed, to match the new standard defined by the WPI Library for 3rd-party libraries.

This new location is:

C:\Users\<username>\wpilib\user\java\lib

This actually makes things simpler to configure in Eclipse than in previous years, but it involves a change to the Eclipse library paths.

Please review the RoboRIO Java Library instructions for Configuring Eclipse Library Paths, which have been recently updated to reflect this new location.

Thanks a lot. That was the missing step.

If Kauai Labs creates a Java tank drive "straight-line driving" example using the WPI Library RobotDrive class, would your team be able to spend some time testing it? I realize everyone's busy right now...

Thanks in advance,

Mr. B

Please take a look at this post from a year ago, it might provide some ideas. A few others encountered similar troubles and found workarounds.

https://www.chiefdelphi.com/forums/s...d.php?t=143307

What you are encountering is an issue that appears on a small percentage of Windows computers.

As background, STDFUFiles.DLL is a user-mode driver from ST Microelectronics which provides USB-based access to the STM32 micro-controller firmware loader. This is used by the navXFirmwareUpdater. The navX-MXP/Micro setup programs install STDUFiles.DLL (using an installer from ST Microelectronics). There are two points:

- Certain operating system privileges are required to install this.
- STDUFiles.DLL is dependent upon some other DLLs, and it's possible they're either not getting installed, or conflict with other DLLs already on your machine.

So in addition to reviewing this post, I'd encourage you to run the navX-MXP/navX-Micro setup program as an administrator.

If that doesn't work, please send details about the configuration of your two computers (operating system version, 32 vs 64 bit, what are the privileges of the account you are using when installing, and anything else you might think is helpful).

If all else fails, we'll can replace your board with one that has the latest firmware (support@kauailabs.com), but let's see if we can resolve it using the above means first.

Aloha,
