*** Releases and Change Log ***
*****************************************************************************
*** Next ***
- NEW: The callback of drivers with circular buffers (ADC, DAC, I2S, SPI) has
been simplified, no parameters. A driver function xxxIsBufferComplete()
has been added to determine if it is the half buffer callback or the
final callback.
- NEW: 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.
- NEW: 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: Added UART7/8 support to STM32 UART USARTv1 driver.
- NEW: Added persistent storage interface to the STM32 RTCv2 driver.
- NEW: STM32 RTCv2 driver now supports callbacks on events.
- NEW: Added an EXTI helper driver for STM32.
- NEW: Added demo for STM32L4R9I-Discovery board.
- NEW: Support for new serial NOR device MX25LM51245G. Other Macronix devices
should work but not tested.
- NEW: Serial NOR flash infrastructure reworked and made simpler.
- NEW_ Modified the RTC driver to implement the persistent storage interface
instead of files interface.
- NEW: Added a new "persistent storage" base class to HAL.
- NEW: Added support for TIM21 and TIM22 in STM32 GPT driver.
- NEW: Reinforced checks in TIM-related drivers.
- NEW: Added support for STM32L072 and STM32L073.
- NEW: Added chThdResume() function to NIL.
- NEW: Removed QSPI driver model, entirely replaced by WSPI.
- NEW: Added demos regarding WSPI, serial nor driver and MFS.
- NEW: Modified the serial nor driver to work with WSPI instead of QSPI,
improved it in several way, simplicity mainly.
- NEW: Added an STM32 QUADSPIv1 implementation for WSPI.
- NEW: Added a new WSPI driver model to HAL, it is a redesign of the
existing QSPI for generic "Wide SPI" interfaces. It now supports up
to eight data lines so "quad" was no more appropriate.
- NEW: Added a new SIO driver model to HAL, it is a low level abstraction of
an UART.
- NEW: Independent TRNG driver model added to HAL. Implemented a RNGv1 driver
for STM32, added test application.
- NEW: Added a new "pipes" subsystem to the OS library.
- NEW: Added mcuconf.h generators for STM32L432xx, STM32L476xx, STM32L496xx,
STM32L4Rxxx, STM32F72x/73x, STM32F746/756, STM32F76x/77x, STM32F413xx
and STM32F303xx devices.
- NEW: Added demo for STM32L496ZG-Nucleo144 and STM32L4R5ZI-Nucleo144 boards.
- NEW: Modified USARTv2 to support HW FIFOs where present.
- NEW: STM32 DMAv1, ADCv3, DACv1, I2Cv2, SPIv2 and USARTv2 are now
DMAMUX-aware.
- NEW: Introduced support for STM32L4+ devices.
- NEW: TRNG API now takes a new "size" parameter, the API can now generate
random numbers of variable size. The crypto driver now does not store
a copy of the transient key inside, the low level can do that if
required.
- NEW: Added analog watchdog functionality to STM32 ADCv2 driver.
- NEW: Added a termination check to the shell.
- NEW: Updated CMSIS to version 5.4.0.
- NEW: Now chconf.h files have preprocessor checks around each definition,
this allows to override settings from makefiles.
- NEW: Added new functions to I/O queues: qSetLink()(backported to 18.2.2).
- NEW: Added new functions to objects fifos: chFifoReturnObjectS()(backported
to 18.2.2),
chFifoSendObjectAheadI(), chFifoSendObjectAheadS() and
chFifoSendObjectAhead()(backported to 18.2.2).
- NEW: Added new functions to guarded pools: chGuardedPoolFreeS() and
chGuardedPoolAddS().
- NEW: Added initializer sections for flash0...flash7 memory areas in
GCC Cortex-M linker scripts.
- NEW: Added support for oversampling in STM32 ADCv3 driver.
- NEW: 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.
- NEW: Added optional support for character match callback in the UART
high level driver.
- NEW: Change, chMtxGetNextMutexS() renamed to chMtxGetNextMutexX().
- NEW: RT 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.
- NEW: Updated STM32L4xx headers to version 1.11.0.
- NEW: Added HAL support for STM32L443.
- NEW: Added support for LDM303AGR 6 axis Accelerometer\Magnetometer MEMS.
- NEW: Added support for LSM6DSL 6 axis Accelerometer\Gyroscope MEMS.
- NEW: Added support for LPS22HB 2 axis Barometer\Thermometer MEMS.
- NEW: 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.
