GPIO console support, new target SWIMCOM, improved configuration options
This release prepares the code for the support of a wide variety of target boards.
The most important changes are:
- improved console communication options, e.g. through a single port D GPIO pin like PD1/SWIM
- simultaneous communication in console and background task is possible (UART and software RxD/TxD)
- configurable character I/O code is now part of the core
- board I/O code (board key input, 7S-LED output) was split into core and board code
- a new target SWIMCOM with console communication through PD1/SWIM was added for exploring unknown boards.
