To get the most out of this book

• You should have a little knowledge of a non-graphical text editor such as vi , emacs, or nano. You can't connect an LCD display, a keyboard, and a mouse directly to the embedded kit to carry out little modifications to text files, so you should have a working knowledge of these tools to do such modifications remotely.
• You should know how to manage an Ubuntu system, or at least a generic GNU/Linux-based one. My host PC is running on Ubuntu 18.04.1 LTS, but you can use also a newer Ubuntu LTS release, or a Debian-based system with a few modifications. You can also use another GNU/Linux distribution, but this will require a little effort from you, mainly with regard to the installation of cross-compile tools, libraries dependencies, and package management.
  Foreign systems, such as Windows, macOS, and others, are not covered by this book due the fact that you should not use low-tech systems to develop code for a high-tech system!
• Working knowledge of the C programming language, how a C compiler works, and how to manage a makefile are all mandatory requirements.
