*** Releases and Change Log ***
*****************************************************************************
*** Next ***
- NEW: Added circular continuous mode to the SPI driver.
- NEW: Added callbacks capability to the CAN driver.
- NEW: Added initial STM32H7xx support.
- NEW: Added GHS compiler support to the Power e200 port.
- NEW: Added tool for board files generation from command line.
- NEW: Added STM32L496xx/STM32L4A6xx support.
- NEW: Added STM32F030x4 support.
- NEW: Added a Managed Flash Storage module to the HAL.
- NEW: Modified the STM32 OTGv1 driver to work without pump thread, transfers
are now done in the ISR.
- NEW: Added I-class functions to the serial driver: sdGetI(), sdReadI(),
sdPutI() and sdWriteI().
- NEW: Modified the HAL queues to improve performance. Added new
functions iqGetI(), iqReadI(), oqPutI() and oqWriteI().
- NEW: Added an "Objects FIFO" object to the OS Library, it allows to
exchange complex objects between threads/ISRs. It is based on a
mailbox and a guarded memory pool.
- NEW: Added an "Objects Factory" to the OS Library, it allows to dynamically
allocate reference-counted kernel objects/buffers or to register
static objects. Allocated/registered objects can be retrieved by name.
- NEW: The OS Library now has its own test suite.
- NEW: Updated STM32F1xx headers to 1.6, STM32F3xx to 1.9, STM32L0xx to 1.10,
STM32L4xx to 1.9, STM32H7xx to 1.1.
- NEW: Updated CMSIS to 5.1.1, changed directories organization under
/os/ext/ARM/CMSIS to match the one in CMSIS, removed /os/ext/CMSIS.
- NEW: Integrated lwIP 2.0.3 and improved lwIP bindings.
- NEW: The chconf.h configuration files now are tagged with the version
number for safety. The system rejects obsolete files during
compilation. Stronger checks are performed on chconf.h, now missing
settings trigger an error instead of getting a default.
- NEW: Added alignment capability to memory pools.
- NEW: Mailbox API changed by adding "Timeout" to those function that have
timeout capability, for consistency with the rest of the system.
- NEW: Modified mailboxes to use a size_t as counter instead of a cnt_t,
this is a leftover of semaphores in previous mailboxes implementation.
- NEW: Added a new functions to RT events chEvtGetAndClearEventsI() and
chEvtAddEventsI().
- NEW: Integrated the latest FatFS 0.13 with patches.
- NEW: Improved RT and NIL test suite to report version numbers and
configuration settings. Now it is possible to run multiple test suites
in the same application.
- NEW: Added a test suite generator tool written in FTL.
- NEW: Added a multi-target demo applications for PAL, SPI and USB-CDC
showcasing how to manage a project with multiple target boards/devices
and handle portability issues.
- NEW: Added to the HAL USB driver a new function usbWakeupHost() for
standby exit.
- NEW: SPI driver improvements, now it is possible to select different
modes for CS line handling.
- NEW: Implemented PAL enhancements on all existing STM32 ports.
- NEW: PAL driver enhanced with improved callbacks capability and new
synchronous API for edge synchronization.
- NEW: Added to the serial driver and channels interface a new "control"
function that allows to implement extensions in the LLD without
touching the high level interface. Conceptually it is similar
to Posix ioctl().
- NEW: Added an argument to PAL events callback. API changed thus this
causes a major number change in HAL.
- NEW: Added shared Eclipse debug configurations for OpenOCD under
./tools/eclipse/debug. Now it is no more required to re-create
those each time a new workspace is created, just import the global
ChibiOS project in it. The configurations will appear under the
Eclipse Tools menu. It is required to create an OPENOCD environment
variable pointing to the OpenOCD executable. It will be done in
ChibiStudio 20 by default.
- NEW: Now .mk files are able to add their files to a common directory,
there is no more need to edit various variables in Makefiles
anymore.
- NEW: Added to new makefiles the ability to recursively compile everything
placed under ./source, if present.
- NEW: Improved the various rules.mk to handle "touching" of all
included makefiles, now the makefile is no more assumed to
be called "Makefile".
- NEW: Added to the Makefiles the ability to change the default build,
dependencies and configuration directories. This makes possible
to have multiple non-conflicting makefiles in the same project.
Updated the various platform.mk implementing "smart build" mode.
