“Download.zip” is to download “all” files from github repository. It doesn’t require much time. After done, simply choose the file of your interest (inside example, Inc or Src directory). Example contains applications for arduino or stm32 systems, Inc contains important files such as stone.h and stone.config.h extremely necessary to use stone serial library. Src contains stone_receive.h and stone_transport.h. You need all these files to make stone serial library working.
