*****************************************************************************
** ChibiOS/RT port for x86 into a Win32 process **
*****************************************************************************
** TARGET **
The demo runs under any Windows version as an application program. The serial
I/O is simulated over TCP/IP sockets.
** The Demo **
The demo listens on the two serial ports, when a connection is detected a
thread is started that serves a small command shell.
The demo shows how to create/terminate threads at runtime, how to listen to
events, how to work with serial ports, how to use the messages.
You can develop your ChibiOS/RT application using this demo as a simulator
then you can recompile it for a different architecture.
See demo.c for details.
** Build Procedure **
The demo was built using the MinGW toolchain.
** Connect to the demo **
In order to connect to the demo a telnet client is required. A good choice
is PuTTY:
http://www.putty.org/
Host Name: 127.0.0.1
Port: 29001 and/or 29002
Connection Type: Raw
