@Gina et all, I have just released astroberry-diy drivers (including focuser, relays and system info). This version is independent of WiringPi and BCM2835 low level control libraries. Instead I decided to use the latest libgpiod, which uses mainland kernel character device. This makes the driver totally independent from any external library. As for now the driver need some testing so it is kept in separate branch. As soon as you test it and confirm it works ok I will move it to master branch and release debian packages. You can grab the source code by running:

git clone https://github.com/rkaczorek/astroberry-diy.git
cd astroberry-diy
git checkout libgpiod

Make sure that you have libgpiod-dev package installed before compiling this version. The compilation should go smoothly by running:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make
make install

Please let me know if it works as designed

Thanks @RadekKI'll try that.

BTW. I took my time and added GPIO pins configuration to Options Tab. No more recompiling if custom pins are used!
