Proxy service for working with weighing scales (only HID-compatible for now)
- libusb-1.0 (libusb-1.0-0-dev package in debian-based distributives)
$PROOF_PATH is compulsory for both build and run-time. It should point to directory where Proof binaries and includes (i.e. artifacts of Proof compilation) are placed.
Set $QMAKEFEATURES var to $PROOF_PATH/features dir (needed only for build itself).
Build process:
mkdir build
cd build
qmake ../proofservice-weighing-scale.pro
make -jNWhere N is number of compile tasks that will run in parallel.
Config changes are applied only at service restart. If service was installed using deb package then auto restarter should be enabled and simple kill -9 SERVICE_PID will work.
Usually scale device will be created with root-only access. To fix it add file /etc/udev/rules.d/50-ultegra-scale.rules (name can be different) with next content (change vendor and product ids to relevant ones):
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0b67", ATTRS{idProduct}=="555e", GROUP="dialout", MODE="0666"

# HID vendor and product ids (can be retrieved from lsusb output)
