and chEvtBroadcastFlagsI(). The old chEvtBroadcast() and chEvtBroadcastI()
become macros. The new functions allow to add the same flags to all the
registered listener threads.
- CHANGE: The functions chEvtSignal() and chEvtSignalI() have been renamed
to chEvtSignalFlags() and chEvtSignalFlagsI() for consistency.
- NEW: Added I-Class functions to the MailBoxes subsystem, now it is
possible to use them as a transport layer between ISRs and Threads
(backported to 2.2.2).
- NEW: Added experimental generic USB driver, it will evolve in next
- NEW: Added new USB driver model, probably it will evolve in next
releases.
- NEW: Added an experimental USB driver implementation for STM32.
- NEW: Added experimental "serial over USB" driver, it implements a
Communication Device Class exposing it as a normal serial driver to
applications, probably it will evolve in next releases.
- NEW: USB driver implementation for STM32.
- NEW: Added "serial over USB" driver, it implements a Communication
Device Class exposing it as a normal serial driver to applications,
probably it will evolve in next releases.
- NEW: Added USB CDC loopback test application.
- NEW: Added new GPT driver model, General Purpose Timer. The driver
allows to access the available timers in an abstract way.
- NEW: GTP driver implementation for STM32.
- NEW: Implemented new event IO_TRANSMISSION_END in the generic serial
driver. This event marks the physical transmission end of a data stream.
- NEW: Implemented the new IO_TRANSMISSION_END event in the STM32 serial
driver.
- NEW: Added explicit reset of all peripherals inside the STM32 HAL driver.
- OPT: Removed TIMx reset on system startup in the STM32 PWM driver, the
timers are already reset on driver startup.
- CHANGE: The functions chEvtSignal() and chEvtSignalI() have been renamed
to chEvtSignalFlags() and chEvtSignalFlagsI() for consistency.
- CHANGE: Swapped the numeric values of the TIME_IMMEDIATE and TIME_INFINITE
constants. Fixed the relative documentation in various places (backported
to 2.2.2).

** ChibiOS/RT HAL - PWM driver demo for STM32. **
*****************************************************************************
** TARGET **
The demo will on an Olimex STM32-P103 board.
** The Demo **
The application demonstrates the use of the STM32 PWM driver.
** 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 ports.
** 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 distribited
with ChibiOS/RT, you can find the whole library on the ST web site:

? Make thread functions return void and add a CH_THREAD macro for threads
