Basics

Last edited by Alvise de'Faveri

Here are some concepts which are useful to know before starting to deal with skyward, boardcore and embedded development.

Embedded Systems

If you are reading this guide, it is very likely that you will work on some kind embedded system sooner or later, so it's useful to know some basics. Here 🔗 you can find some presentations we did on the topic, in particular:

Moreover, it is a good idea to know something about how these work:

  • USART, I2C, SPI
  • Interrupts
  • PWM

C++

C++ is a quite vast language that can be very powerful, but also very dangerous for those who don't know it. You can approach it by reading about some of these things:

  • inheritance, children, instances
  • what's a header file (.h) and what goes there
  • namespaces
  • scopes
  • references vs pointers
  • virtual
  • std::vector and std::map
  • cin and cout
  • templates
  • static and dynamic allocation

Also some basic C knowledge is required, such as:

  • malloc
  • stdint.h that contains things like uint8_t, int32_t etc
  • bitwise operands <<, >>, & and |
  • #define

Git

We use Git as our source version control system, and we love it. Git is fun, but you should be very careful of doing it the right way:

  • Commit messages should always be
[topic] Short description
*blank line*
Long description

Style

Follow our Codestyle guide. Really, do it. As a quick recap:

  • Never use printf(), use TRACE() instead
  • Every class and function you write should have Doxygen comments like this
  • Download the clang-format plugin for your favourite IDE and tell it to apply our .clang-format style

Miosix and Multithreading

Sice we are using an Operating System, you have to be aware of what multithreading is. Taking a look at this presentation will give you all the information you need, and even something more.
