If you want to use the Sense HAT without resorting to sudo or root, you need to add some udev rules to permit access to regular users. There’s plenty in there that deal with the various environmental sensors, the display, the joystick, and the IMU on the HAT. You can try the same and watch the reading spike up before falling back down.Īt this point, I’d suggest having a play with the other demo scripts available in the emulator.
In the image above, the reading is quite high as I’ve just breathed on the HAT. This is my Sense HAT, mounted on a Pimoroni Black HAT Hacker board (because it makes it far easier to wiggle around without worrying about HDMI cables and such): Let’s get started with installing the HAT. Secondly, if you do have a Sense HAT, then you can use all the demo scripts that come with it! Firstly, you can play with it even if you don’t have a Sense HAT. We’ll start with the Sense HAT desktop emulator package for a couple of reasons (full disclosure: these reasons have nothing whatsoever to do with my having written it … no sir!).

How to set up the Sense HAT desktop emulator sense-emu-tools - The Sense HAT desktop emulator package, which includes the GUI desktop emulator and the sense_rec and sense_play tools.(Note: there’s no corresponding python-sense-hat library for Python 2.x on Ubuntu because Python 2.x is no longer supported.) python3-sense-hat - The official Python library for interfacing to the Sense HAT.sense-hat - The main Sense HAT package which depends on all the other bits you’ll need (like the Python library detailed below) and a basic configuration with some reasonable calibration figures.
Thanks in advance for any help you can provide.One of the main new features in Impish Indri for the Raspberry Pi is the addition of packages to support the Raspberry Pi Sense HAT. Alternatively, it was implied I might have to wait for years for Gtk 4.0 to be offered. It was suggested I could build my own Gtk 4 compiler using the open source code, however when I attempted to do that, I kept getting additional errors. When I mentioned this in the Gtk forum, I pointed out that Gtk 3.0 was supported, but I was told this is likely because Gtk 3.0 had been out for nearly a decade. Now, with the release of Gtk 4.0, I hear it is currently unavailable for Debian (Raspberry Pi Os) and the following command fails: Still, I was able to press on, ending up with a fairly impressive application. The only struggle was the abundance of library functions that were deprecated.

I was able to use the above instead (sudo apt-get install libgtk-3-dev) and it worked great. I first got started using Simon Long’s “C & GUI Programming” book which referenced Gtk 2.0 and provided a command to install that is similar to the above (sudo apt-get install libgtk-2-dev). This it, add this to your project source file and off you go. For subsequent ones you can simply 'duplicate' and then 'edit' to add each as a new entry. For the first one you can paste the line in even though an open file dialog is shown but you may need to go back and edit it to make it right. Go to: Project Properties > Build > C++ Compiler > General > Include Directories > and add in each one. usr/lib/arm-linux-gnueabihf/glib-2.0/include usr/lib/arm-linux-gnueabihf/dbus-1.0/include pthread -I/usr/include/gtk-3.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/at-spi-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/arm-linux-gnueabihf/dbus-1.0/include -I/usr/include/gtk-3.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng12 -I/usr/include/glib-2.0 -I/usr/lib/arm-linux-gnueabihf/glib-2.0/includeĬonvert it into a list of directories and delete any duplicates, so you end up with something like this: Now you need to add all of the directories used by the gtk libraries – dull but necessary… Use this command: Note the single quote marks are correct and should be used as is! `pkg-config –cflags gtk+-3.0` `pkg-config –libs gtk+-3.0` Go to: Project Properties > Build > Linker > Compilation Line > Additional Options > paste in this: Include gtk and get programming – see here.
