Does MathWorks provide any tools for automatically generating flight code for the Pixhawk platform?

I am using the Pixhawk autopilot system designed by the PX4 open-hardware project by 3D Robotics. Is there an existing Simulink library block-set for generating embedded C-code from Simulink for this platform?

[MathWorks Aerospace Products Team]

A new version of the Pixhawk Pilot Support Package (Version 1.3) has been released for MATLAB R2015b.

http://www.mathworks.com/hardware-support/pixhawk.html

This release incorporates the following changes:

1) Added high-resolution timer (HRT) for posting the base-rate semaphore in the Nuttxinitialize.c scheduling code

2) Forked Firmware tied to Pixhawk PSP upgraded to Release v1.0.0 https://github.com/PX4/Firmware/releases/tag/v1.0.0

3) uORB Topic blocks for publishing and subscribing data

4) Ability to model asynchronous tasks that are driven by uORB topic events

5) ADC block support

6) Serial Rx/Tx Block support

7) Ability to read flight parameters in the generated code using storage classes

See: https://pixhawk.org/firmware/parameters

7) Various bug fixes

Included are also examples/tutorials that go over some of these new features.

NOTE: The R2015a and R2014b release of the Pixhawk PSP contain the exact same set of features and are considered the same version (Version 1.2) and represent the first public release. Please consult the documentation to learn more about the features contained within Release 1.2.

[MathWorks Aerospace Products Team]

MathWorks has developed a Pixhawk Pilot Support Package (PSP) which provides a suite of Simulink blocks to target and interface with the Pixhawk FMU. To download the support package go to this page:

http://www.mathworks.com/hardware-support/pixhawk.html

Please note that only MATLAB R2014b is supported at this moment.

[Steve Kuznicki]

R2015a is now supported.

Hi All,

The official support package - 'Embedded Coder support Package for PX4 Autopilots' is now live from R2018b onwards.

[Ahmad Drak]

is there a release for ubuntu? running matlab 2016a?

[Walter Roberson]

Sorry, at present (early July 2016) it is only MS Windows.

I think R2016a is supported, but I am not positive.

[Ahmad Drak]

2016a is not supported. Only 2015b

I am getting the following error: "Failed to load library 'AR_Drone_Positioning' referenced by 'Green_Ball_Tracking_Mounted/Flight Controller'". Can you please help?

Are there plans to upgrade PSP support for MATLAB 2017b?

[Ningjun Liu]

Or probably support for Pixhawk2? That controller has more redundancy and better connectors.

[Mahmud Khan]

The update you asked for has been released.

hi Mahmud, thanks for that answer. Yes the PSP has been updated to support R2017a/b. My own question is, where can I find an updated userguide to enable me setup the pixhawk psp on R2017a. The only one availabe/or which i've seen onliine is the one released in February 2017 appicable to matlab R2016. Thanks.

[Walter Roberson]

The bottom of https://www.mathworks.com/hardware-support/pixhawk.html currently says,

"This support package is available for 64-bit Microsoft® Windows® and Linux. This version of the support package is compatible with MATLAB R2017a and R2017b. It also works in MATLAB R2018a with limitations to External Mode functionality."

My OS is win10, Matlab is 2017b

these were what i have done and met:

download bash,install it.

download PSP, install it in matlab,

download Python, install it.

In the PSP UI, validate path, no problem. push download firmware button, after a whole night ,finished, on problem.

If i push the 'save setting and exit' button first ,error will tell no firmware, so I download firmware first.

install other tools by running 'windows_bash_nuttx.sh', error met as below:

do not know how to fix it.

then push build button ,met these message:

can not go on, how can i fix these?

[Matija Krznar]

They have created this script with windows editor and because of that linux have problems with space and newline.

Install a tool dos2unix and run it on script.

install:

sudo apt-get update
sudo apt-get install dos2unix

then use it on script:

dos2unix windows_bash_nuttx.sh

it worked for me.

[Stephen Warwick]

Is support for R2018b planned in the near future? Will this block set be regularly updated for new versions. Just curious whether I should migrate or not to the newer version of Matlab/Simulink. Thank you

[Mahmud Khan]

I can't even make it work with R2017a (yet).

I followed the instructions provided in the download page. It results in this error during the installation and its not like there's any support material/group to help anyone through all that.

Did you get to try it out?
