albert
This is a custom linux image for the raspberry pi built with BuildRoot. UI built with QT which just charts randomly generated numbers in real time.
Dev
Deps
sudo pacman -S cmake qt5-base qt5-charts qt5-quickcontrols qt5-quickcontrols2
Building the UI
cd br-ext-tree/package/albert
mkdir build && cd build
cmake ..
make
Building the Temperature Sensor Systemd Dbus Server
cd br-ext-tree/package/temperature-sensor
mkdir build && cd build
cmake ..
make
Building the OS image
make build
Basically this generates the custom config defined for this board and calls make in the buildroot submodule, providing the custom packages built in this repo to the build process via Buildroot's external tree argument. On build complete, an image will be at buildroot/output/images/sdcard.img
Flashing RPI
My machine has two drives so USBs are generally /dev/sdc for me and is hardcoded in the Makefile, this probably needs to be modified depending on your setup (lsblk, change the SD_DEVICE variable) . Assuming the OS image has been built and exists at ./buildroot/output/images/sdcard.img, running:
make flash
will just dd it into the SD card.
Running Flashed Program
Plugging the SD card in, it boots into a login prompt with credentials root and pass. To start the UI:
$ albert-ui
