version. For example it is possible to compile the RPP library for
Linux (using POSIX version of the FreeRTOS), which can be desirable
The following FreeRTOS versions are distributed:

- \item[6.0.4\_posix] POSIX version, usable for compilation of the library

\subsection{System Layer}
\label{sec-system-layer}
This layer contains system files with data types definitions, clock definitions,
folder.
Large part of this layer was generated by the HalCoGen tool (see
-Section~\ref{sec-halcogen}).

-\subsection{HAL abstraction layer}
-\label{sec-hal-abstraction-layer}
-Hardware Abstraction Layer (HAL) provides an abstraction over the real
-hardware. For example imagine an IO port with 8 pins. First four pins
-are connected directly to the GPIO pins on the MCU, another four pins
-are connected to an external integrated circuit, communicating with
-the MCU via SPI. This layer allows to control the IO pins
-independently of how that are connected to the MCU, providing a single
-unified API.
-
-Note that this functionality is not needed in the current version for
-\tgtBoardName, because all IOs are controlled directly by GPIO pins.
-
-As a result, the higher layers do not have to know anything about the
-wiring of the peripherals, they can just call read, write or configure
-function with a pin name as a parameter and the HAL handles all the
-details.
-
-The source files can be found in
-\texttt{$\langle$rpp\_lib$\rangle$/rpp/src/hal} and the header files can
-be found in \texttt{$\langle$rpp\_lib$\rangle$/rpp/include/hal} folder.

\subsection{Drivers layer}
\label{sec-drivers-layer}
The Drivers layer contains code for controlling the RPP peripherals.
Typically, it contains code implementing IRQ handling, software
queues, management threads, etc. The layer benefits from the lower

We suggest to provide a similar header file for your operating system as
well.
