*** Releases ***
*****************************************************************************
*** 0.4.0 ***
- Implemented a debug subsystem, it supports debug messages and a context
switch circular trace buffer. The debug code can be enabled/disabled by
using the CH_USE_DEBUG in chconf.h.
The trace buffer is meant to be fetched and decoded by an external tool
(coming soon, it can be accessed using JTAG in the meanwhile).
- Implemented panic messages when CH_USE_DEBUG is enabled.
- Added a thread identifier field to the Thread structure, it is used only
for debug.
- Fixed an harmless warning message in buzzer.c.
*** 0.3.6 ***
- Added SSP (SPI1) and ext.interrupts definitions to the lpc214x.h file.
- Added SSP driver for the LPC2148.
