Quickstart

Preparing the environment

apt-get install -y gcc-arm-none-eabi gdb-arm-none-eabi git make cmake libgtk-3-dev libusb-1.0-0-dev build-essential dpkg-dev
https://github.com/texane/stlink
cd stlink
dpkg-buildpackage -rfakeroot
dpkg -i ../*stlink*.deb
cd
cat > ~/.gdb-load-firmware << EOF
target remote :4242
load
EOF

cd && git clone https://devel.mephi.ru/dyokunev/disabled-people-button
cd ~/disabled-people-button && git submodule update --init --recursive

Loading the firmware on a sensor

cd ~/disabled-people-button/sensor/firmware
make
st-util &
gdb -x ~/.gdb-load-firmware build/*.elf

(also you can change SENSOR_ID value in file Src/main.c)

Loading the firmware on a receiver

cd ~/disabled-people-button/receiver/firmware
make
st-util &
gdb -x ~/.gdb-load-firmware build/*.elf
