pi@raspberrypi:~ $ cd honey_dispenser
pi@raspberrypi:~/honey_dispenser $ chmod +x install_and_start.sh
pi@raspberrypi:~/honey_dispenser $ ./install_and_start.sh

Manual Install

• Set rpi to performance mode:

    echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

• lgpio-dev is required to be installed. It may be available to you via apt:

sudo apt-get install -y liblgpio-dev

If it is not available, manually build and install it by following the instructions here.

• Install C++ dependency for python library

pi@raspberrypi:~ $ git clone --depth=1 https://github.com/endail/hx711
pi@raspberrypi:~ $ cd hx711

For RPi 5 the expansion header GPIO pins are now on /dev/gpiochip4 instead of /dev/gpiochip0. endail/hx711/issues/85

pi@raspberrypi:~/hx711 $ cd src
pi@raspberrypi:~/hx711/src $ sed -i 's/Utility::openGpioHandle(0)/Utility::openGpioHandle(4)/g' HX711.cpp
pi@raspberrypi:~/hx711/src $ cd ..
