pub struct B15F {}Structure representing the driver for the board 15
-Creates a new instance of the B15
+pub struct B15F { /* private fields */ }Structure representing the driver for the board 15
+Creates a new instance of the B15
This function will establish a connection to a connected B15 and return
a handle to interact with it. Only one such instance should exist per
program; calling B15F::new() more than once might lead to unexpected
behaviour.

It aims to be syntactically similar to the original implementation.
The original repository is no longer maintained, and this library doesn’t maintain it either,
it simply provides the same functionality in another language.
