+*****************************************************************************
+** ChibiOS/RT port for ARM-Cortex-M4 STM32F407. **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an ST STM32F4-Discovery board.
+
+** The Demo **
+
+The demo shows how to use PWM and SPI drivers using synchronous APIs. The PWM
+driver the four board lets with the data read from the LIS320DL accelerometer.
+The data is also transmitted on the SPI2 port.
+By pressing the button located on the board the test procedure is activated
+with output on the serial port SD2 (USART2).
+
+** Build Procedure **
+
+The demo has been tested by using the free Codesourcery GCC-based toolchain
+and YAGARTO. just modify the TRGT line in the makefile in order to use
+different GCC toolchains.
+
+** Notes **
+
+Some files used by the demo are not part of ChibiOS/RT but are copyright of
+ST Microelectronics and are licensed under a different license.
+Also note that not all the files present in the ST library are distributed
+with ChibiOS/RT, you can find the whole library on the ST web site:

3484947)(backported to 2.4.1).
- FIX: Fixed various minor documentation errors (bug 3484942)(backported
to 2.4.1).
+- NEW: Added another STM32F4-Discovery demo using the on-board MEMS, SPI
+ and PWM. Removed MEMS handling from the old demo because code size limits
+ on non-free compilers.
- NEW: Added configuration wizard plugin under ./tools/eclipse/plugins. This
first version is able to configure the board files for STM32F0xx, STM32F4xx
and STM32L1xx.
