******************************************************************************
*** ChibiOS 19.1.0 Release Notes. ***
******************************************************************************
ChibiOS 19.1.0 is composed of several independent but inter-operable
sub-projects: RT, NIL, HAL, EX. Plus several external libraries
integrated in our structure: WolfSSL, FatFS and lwIP.
*** ChibiOS 19.1.0 highlights ****
This release is focused on features and general improvements, HAL, RT and NIL
received a series of important improvements, new features have been added.
*** ChibiOS 19.1.0 general improvements ***
- CMSIS 5.4.0 has been integrated.
- Improved build system based on make.
- Now it is possible to define separate directories for each configuration
file.
- Demo projects reworked to use the new make system and remove configuration
files from the root.
- Linker scripts improvements.
*** What's new in RT/NIL ports ***
- Added a sanity check on GCC version for ARMv6-M, a version below 6
must be used.
*** What's new in OS Library 1.1.0 ***
- Separated OSLIB from RT and NIL, now it is a separate "product" with
its own version, configuration file and licensing. The library will
grow to include more functionalities.
RT and NIL will contain only the core functionalities, everything else
is shared library code.
- Added a new "pipes" subsystem.
- Many improvements in Memory Pools, Object FIFOs.
- Stricter alignment checks in memory pools.
- chFifoObjectInit() renamed to chFifoObjectInitAligned(). Added a new
chFifoObjectInit() without the alignment parameter.
*** What's new in RT 6.0.0 ***
- C++ wrapper reworked, now it is mostly inline code, added some new
wrappers and methods. Added wrappers for more API functions. BaseThreads
are no more descendants of ThreadReference.
- Change, chMtxGetNextMutexS() renamed to chMtxGetNextMutexX().
- Added a new function chMtxGetOwnerI() to mutexes.
*** What's new in NIL 3.2.0 ***
- Added chThdResume() function.
*** What's new in HAL 7.0.0 ***
- Added new SIO, TRNG, WSPI driver models.
- Removed EXT, QSPI driver models.
- Removed TRNG functionality from CRY driver.
- Low level drivers simplification. There is a new template of LLD, now
driver and configuration types are defined in the HLD, LLD just exports
macros with the fields to be added to the structures.
So far the drivers updated are: ADC, DAC, I2S, RTC, SPI, TRNG, WSPI.
- New infrastructure for Serial NOR Flash devices.
- New and improved MFS subsystem.
- Improved CRY driver with better keys loading.
- Added a new "persistent storage" base class.
- Modified the RTC driver to implement the persistent storage interface
instead of files interface.
- Added optional support for character match callback in the UART
high level driver.
- Added new functions to I/O queues: qSetLink().
- ADC driver state machine change, now the state ADC_COMPLETE is set
before calling the 2nd callback even in circular mode. This has been
done for consistency with other drivers with circular buffers.
- The callbacks of drivers with circular buffers (ADC, DAC, I2S, SPI) have
been simplified, no parameters. A driver function xxxIsBufferComplete()
has been added to determine if it is the half buffer callback or the
final callback.
- Event enable check API added to PAL driver.
*** What's new in EX 1.1.0 ***
- All drivers updated.
- Added support for LDM303AGR 6 axis Accelerometer\Magnetometer MEMS.
- Added support for LSM6DSL 6 axis Accelerometer\Gyroscope MEMS.
- Added support for LPS22HB 2 axis Barometer\Thermometer MEMS.
*** What's new in AVR HAL support ***
*** What's new in STM32 HAL support ***
- Introduced support for STM32L4+ devices.
- Added support for STM32L433 and STM32L443.
- Added support for STM32L072 and STM32L073.
- Added support for TIM21 and TIM22 in STM32 GPT driver.
- Added support for TIM15, TIM16 and TIM17 on GPT, ICU and PWM drivers.
- Both DMAv1 and DMAv2 have been reworked to support DMAMUX, DMAv3 has
been removed. In addition, both drivers are now able to support dynamic
channel allocation.
- Updated all drivers to use the new DMA API.
- Added demos for STM32L496ZG-Nucleo144, STM32L4R5ZI-Nucleo144 and
STM32L4R9I-Discovery boards.
- Updated STM32L4xx headers to version 1.11.0.
- Restructured the STM32F4xx HAL support, added support for STM32F413,
added ability to handle the TIMPRE bit, separated the clock tree in
two distinct implementation to reduce the proliferation of compiler
time conditionals, added more checks to the input parameters.
- Added support for oversampling in STM32 ADCv3 driver.
- Added analog watchdog functionality to STM32 ADCv2 driver.
- STM32 ADCv3, DACv1, I2Cv2, SPIv2 and USARTv2 are now DMAMUX-aware.
- Modified USARTv2 to support HW FIFOs where present.
- Added UART7/8 support to STM32 UART USARTv1 driver.
- Added an EXTI helper driver.
- RTCv2 driver now supports callbacks on events.
- Added option to enable bypass on SDIOv1 driver allowing to use a
50MHz clock.
*** What's new in tools ***
- Added mcuconf.h generators for STM32L432xx, STM32L476xx, STM32L496xx,
STM32L4Rxxx, STM32F72x/73x, STM32F746/756, STM32F76x/77x, STM32F413xx
and STM32F303xx devices.
