9.5. Radio Driver
The radio driver module resides in a low-level driver software layer. It is intended to provide a user-friendly and
easy-to-use API to the radio functionality. It contains API functions and macro definitions for all radio commands.

. Including this driver module into the software project makes
the control of the radio chip easier than ever before through its comprehensive public API functions. The driver
handles all the SPI communication with the chip, including the check for the CTS signal, and automatically reads
the response from the chip. Thanks to the layered approach, it can be easily ported to other architectures and
platforms, as it depends only on the Hardware Application Layer. This means it is enough to port the HAL for a
given architecture in order to get the radio driver work. As introduced in the other drivers, the radio driver also can
be compiled with different support types (Minimal, Extended or Full). Depending on which support type defined, the
radio driver provides different level of API coverage. This way it provides a convenient way of managing the
compile firmware size depending on the API functions usage and excludes the unused and, therefore,
unnecessary functions.
