kandi X-RAY | gpsd Summary

gpsd is a C library typically used in Geo, Map applications. gpsd has low support. However gpsd has 28 bugs, it has 2 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub.

gpsd is a userland daemon acting as a translator between GPS and AIS receivers and their clients. gpsd listens on port 2947 for clients requesting position/time/velocity information. The receivers are expected to generate position information in a well-known format -- as NMEA-0183 sentences, SiRF binary, Rockwell binary, Garmin binary format, or other vendor binary protocols. gpsd takes this information from the GPS and translates it into something uniform and easier to understand for clients. The distribution includes sample clients, application interface libraries, and test/profiling tools. The website for GPSD where you can find updates, news, and project mailing lists is: See that website for a list of GPS units known to be compatible. See the file INSTALL.adoc for installation instructions and some tips on how to troubleshoot your installation. The file build.adoc has instructions for building from source. The packaging/ directory contains resources and suggestions for packagers and distribution integrators. Remco Treffkorn designed and originated the code. Russ Nelson maintained gpsd for a couple of years. Carsten Tschach's gpstrans-0.31b code was the original model for nmea_parse.c. Bob Lorenzini hwm@netcom.com provided testing and feedback. Brook Milligan brook@trillium.NMSU.Edu combined gpsd and gpsclient into one package and autoconfiscated it. Derrick J. Brashear shadow@dementia.org (KB3EGH) added code for the EarthMate DeLorme. He also added "incredibly gross code to output NMEA sentences" (his own words :-) He also did the first cut at DGPS support (see for the Earthmate. Curt Mills BowHunter@mail.com (WE7U) furthered the dgps support, writing the portion for other GPS receivers. None of these people have been active in 2.X and later versions; gpsd has evolved out of recognition from the 1.X codebase. The main feature of the 3.x versions is a stabilized and finalized version of the JSON command/response protocol. This was designed and mainly implemented by ESR. Gary Miller wrote the subframe support.

I have some lines of code that gather NMEA sentences from the gpsmon gpsd command line utility (spawned as a child process) and gathers some internal GPS location data from an external radio. I don't want the user to see the gpsmon output in the terminal when they run the code, so I redirect it /dev/null like so:

That indentation means you have only newlines without carriage returns, and you're rendering into a terminal that's configured to act in a Windows-y way.

On UNIXy systems, the linefeed character also sends the cursor to the left. On Windowsy systems, it only moves the cursor down, and you need a carriage return to send the cursor to the left.

To tell a UNIX terminal to treat a linefeed as if it were both a carriage return and a linefeed, you can use:

I am facing a gpsd issues on petalinux. I have installed the gpsd on petalinux but the gpsd-client was not being installed, thats why gpsd.socket and the gpsd.service files are missing. Can someone tell me if i add these files manually, where i place these files so that gpsd works properly.

gpsd-client is a separate recipe. It's not installed automatically when you install gpsd. You'll need to explicitly call it out in your PetaLinux build. That being said, gpsd is not dependent on gpsd-client so it should work whether gpsd-client is installed or not.

To install gpsd-client:
Open project-spec/meta-user/recipes-core/images/petalinux-image.bbappend
(filename may vary based on version of Petalinux you are using)

add these lines:
IMAGE_INSTALL_append = " gpsd"
IMAGE_INSTALL_append = " gpsd-client"

petalinux-config -c rootfs
user packages --> [x] gpsd
user packages --> [x] gpsd-client

petalinux-build

If gpsd-client fails to build correctly, you may need to add the appropriate layer to the build process. The gpsd-client recipe info can be found in the OpenEmbedded Layer Index.

Yocto bitbake build error when adding fftw package

Asked 2020-Nov-03 at 10:43

I am using Yocto Warrior release to build linux for Dart-imx8m SOM. Documentation can be found here : https://variwiki.com/index.php?title=DART-MX8M_Yocto&release=RELEASE_WARRIOR_V1.1_DART-MX8M.

I want to add fftw package whose recipe is in meta-oe layer. Whenever I add this package in my local.conf file, I get an error with bitbake regarding a dnf related task.

I add the package like this in my local.conf file : IMAGE_INSTALL_append = " fftw"

I get the following error when building image with bitbake fsl-image-gui :

ANSWER

Answered 2020-Nov-02 at 21:11

The fftw recipe is set up to create a few different packages (RPM) like libfftw, libfftwl, libfftwf, fftw-wisdom, fftwl-wisdom, fftwf-wisdom, and fftw-wisdom-to-conf. You probably want to add one or more of those. It seems there is no actual fftw package.

It is important to remember that IMAGE_INSTALL and RDEPEND lists items from the package namespace, while DEPENDS lists items from the recipe namespace.

If you are unsure about which package you want to install you can inspect the packages-split folder for fftw in tmp/work to see which files are included in which package.

QUESTION

periodic polling of port or hardware IO point on Raspberry Pi

Asked 2020-Jul-14 at 17:14

In developing an application using Qt5 with Python, you are generally event driven. No sweat, works like a charm. However, there are instances when you need to poll the status of some hardware GPIO (i.e. a button push), or get some information from a serial port, or something like a gpsd daemon.

What is the preferred way to handle this? Via a QTimer, say, running every 50 msec? Or is there some other method I haven't found? Is it better to set up a trigger on a GPIO pi (https://www.ics.com/blog/control-raspberry-pi-gpio-pins-python) or is there any conflict with the Qt5 Gui?

Basic documentation doesn't look horrible, and I can follow some examples, of course, but didn't know if there was a better/canonical/more Pythonic method.

Answered 2020-Jul-14 at 17:07

I don't think there is a pythonic solution, not because you can't use python but because python is not relevant to the topic. And there is no canonical solution either, everything will depend on the application.

From my experience I have found it much easier to reuse libraries that handle GPIOs like Rpi.GPIO or gpiozero. These libraries have as a strategy to create threads where the state of the pins is monitored, so you cannot use the callbacks directly to update the GUI but you must implement wrapper(see this for example).
