As reported in issue #4214, there are seen issues seen first on
NUCLEO_F103RB in case of successive Reads of 1 byte at a time.
This issue is due to a wrong state management in the end of read sequence.
Also F1 i2c driver was not fully aligned to others, which is updated here.
There were still side effects, in particular on I2C master slave test,
when setting by default the Pin Speed for F1 family. So for F1 family,
let's do it only in case of Output which is the only case where this
actually applies on this family.
* Initialization clear interrupt status
* Remove state in management of interrupt
* Handle timestamp in the past
* Handle current seconds, even if out of the relative timestamp.
* Simplify interrupt handling logic.
For keep supporting external APIs with the same name (supposedly there are a larger
number of users of those APIs), BufferedSerial and ATParser are being renamed.
BufferedSerial becomes UARTSerial, will complement a future USBSerial etc.
ATParser becomes ATCmdParser.
* UARTSerial moves to /drivers
* APN_db.h is moved from platform to cellular/util/.
* Original CellularInterface is restored for backward compatability (again, supposedly there
are users of that).
* A new file, CellularBase is added which will now servce as the base class for all
upcoming drivers.
* Special restructuring for the driver has been undertaken. This makes a clear cut distinction
between an on-board or an off-board implementation.
- PPPCellularInterface is a generic network interface that works with a generic FileHandle
and PPP. A derived class is needed to pass that FileHandle.
- PPPCellularInterface provides some base functionality like network registration, AT setup,
PPP connection etc. Lower level job is delegated to the derived classes and various modem
specific APIs are provided which are supposed to be overridden.
- UARTCellularInterface is derived from PPPCellularInterface. It constructs a FileHandle and
passes it back to PPPCellularInterface as well as provides modem hangupf functionality.
In future we could proive a USBInterface that would derive from PPPCellularInterface and could
pass the FileHandle back.
- OnboardCellularInterface is derived from UARTCellularInterfae and provides hooks to
the target provided implementation of onbard_modem_api.h. An off-board modem, i.e, a modem on
a shield has to override the modem_init(), modem_power_up() etc as it cannot use
onboard_modem_api.h.
* Implements CellularInterface
* Reference design for CellularInterface implementations
* Uses an external mbed-os IP stack and talks to modem over PPP.
This provides a HAL layer for Modem bearing devices.
Provides a standard interface to upper layer drivers.
Platform providers will be implementing this API under their
specific targets.
As a reference, two implementations are provided under TARGET_C027 (UBLOX)
and TARGET_MTS_DRAGONFLY_F411RE (MultiTech).
targets.json now contains a tag "MODEM" which tells that this target
has a modem and the modem_api is protected by a flag DEVICE_MODEM
(following the DEVICE_SERIAL fashion ).
* Lays down ground for mbed modem_api
* Standardizes pin names relating to modem device for UBLOX C027 and MTS_DRAGONFLY_F411RE
devices
* Ublox modem api is changed to use a standard, platform independent name so that same
api could be used with multiple ubloc modems.
* DCD Polarity macro is added to assist the driver in knowing correct polarity
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.
F2 family also require that TIM_AUTORELOAD_PRELOAD_DISABLE is set,
otherwise the field could have undefined value from the stacj and may
lead to undefined behavior.
The error was found using USE_FULL_ASSERT HAL option.
Rather than adding F2 to the list of family, let's set this parameter for
any family where TIM_AUTORELOAD_PRELOAD_DISABLE applies.
When we want to activate USE_FULL_ASSERT macro in STM32 CUBE, there is a
need to have the assert map to MBED.
The easiest way to have this definition in a single place for all STM32
HAL and LL files using it, is to add a specific header file where the
porting to MBED is done.
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.
The STM32F3 cmsis_nvic code is currently checking for a specific flash
address when determining if the vector table is in flash or RAM. By
changing the test to instead see if the vector table base is NOT set to
the RAM address, it simplifies the code, and removes the dependency on
the flash vectors being located at a specific address. This becomes
important when adding a custom boot loader, which requires that the
flash vector table location in the mbed project be at a different
address.
