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
