** The Demo **
The demo currently just toggles the relay using a thread. It will be expanded
in next releases.
The demo currently just writes a hello world on the LCD and toggles the relay
using a thread while button 2 is pressed.
By pressing the button 1 the test suite is activated, output on serial port 2.

it, the changes were required because the type names were a concern for
some users.
- Implemented a serial driver in the AVR port.
- Implemented a simple HD44780 LCD driver into the AVRmega128 demo.
- Reworked the AVR AT90CAN128 port to share the common AVR code.
- Modified the test suite to be compatible with 8 bit micros.
- MSVC demo dropped, it is still possible to use the MinGW demo as simulator
