 The framework incorporates an OSAL providing service abstraction classes of a fictitious operating system that can perform all the operations of a real operating system.
 This layer shows the user an abstraction of the common functionality provided by all real-time operating systems (RTEMS, VxWorks, Azure ThreadX, QNX, FreeRTOS, Zephyr,...) or not (Linux, macOS, WinCE,...). We find the following services:
