C/C++ Language Embedded Programming Fundamentals

The following sub-chapters cover programming fundamentals in C/C++, which comply with most C/C++ notations. Those who feel comfortable in programming will find these chapters somewhat introductory, while for those having no or little experience, it is highly recommended to cover this introduction. This chapter and its sub-chapters target the basics and general syntax of C/C++ programming for different platforms, including Arduino, Espressif, Nordic, STM32, and partially for Raspberry Pi devices; however, in any case, the programming environment configuration is different for every platform. The Arduino programming framework is common for many MCU manufacturers of the IoT Edge class devices in bare metal programming mode, even if it brings some overhead and does not let the developer push the devices to their limits. To enjoy full power, efficiency and control of the specific device, one needs to use a dedicated SDK and Framework, but for teaching purposes and many even professional applications, Arduino Framework is suitable and a good balance between the cost of the development and the result.
