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.
For STM32 targets using a 32-bit timer for the microsecond ticker, the
driver did not properly handle timestamps that are in the past. It
would just blindly set the compare register to the requested timestamp,
resulting in the interrupt being serviced up to 4295 seconds late
(i.e. after the 32-bit timer counts all the way around to hit the
timestamp again).
This problem can easily be reproduced by creating a Timeout object
then calling the timeout's attach_us() member function to attach a
callback with a timeout of 0 us. The callback will not get called for
over 2147 seconds, and possibly up to 4295 seconds late if no other
microsecond ticker events are getting scheduled in the meantime.
Now, after the compare register has been set, the timestamp is checked
against the current time to see if the timestamp is in the past, and
if so, the compare event is manually set.
NOTE: By checking if the timestamp is in the past after configuring the
capture register, we ensure proper handling in the case where the timer
updates past the timestamp while setting the capture register.
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.
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
Reworked the serial_format() function for STM32F0x
devices to take the format in the form:
data_bits - parity - stop_bits
E.g. 8 - N - 1
where data_bits exclude the parity bit.
Added a case for 7 bits data as at least the chips
STM32F0x1/STM32F0x2/STM32F0x8 support 7 bits data.
Consolidated serial_format() and uart_init()
functions into a general TARGET_STM serial_api.c
file since the functions are common to all STM targets.
Fixes#4189
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.
According to @betzw, #3424 was put in for I2S with DMA. However, the latest I2S library now works without this patch.
The changes in DMA HAL for this potentially introduced corner case
scenarios. So it's best to revert the DMA changes.
If you are using Ethernet, and not SPI Arduino pins:
=> keep your board with the default configuration
If you are using SPI Arduino pins, and not Ethernet:
=> you should remove the JP6 bridge on the front side of the board
If you need SPI Arduino and Ethernet:
=> you have to patch the NUCLEO board on the back side: set solder bridge SB121 to off, and SB122 to on
=> D11 is no more connected to PA_7 but to PB_5
=> overwrite d11_configuration config value in json file
When attempting to perform a test build of various mbed-os targets with
GCC configured to build -std=gnu++11, all of the targets built
successfully except for this one. It gave errors like this:
../mbed-os/targets/TARGET_STM/TARGET_STM32F4/TARGET_UBLOX_EVK_ODIN_W2/sdk/wifi_emac/wifi_emac_api.cpp: In function 'emac_interface_t* wifi_emac_get_interface()':

const emac_interface_ops_t ops;
This commit contains a proposed change which fixes this issue by not
using the new operator to allocate the emac_interface_t structure but
instead using the malloc() function since the construction is being
handled explicitly in the subsequent lines of the
wifi_emac_get_interface() function anyway.
I also added code which only completes the initialization of the _intf
object if its allocation succeeds and just returns NULL otherwise.
I see no deallocation of the _intf object occurring so no change from
delete to free() needed to be made.
Revert HRM1017 file source deletion
Added in small comment next to additions
Added mapping to BTN-labelled switches
Added mapping to USER_BUTTON-labelled switches
Undo incorrect mapping to SWIO pin in NORDIC target
Before this patch, many warnings like below were generated
during compilation with ArmCC
[Warning] lwip_ethernet.h@57,0: #3135-D: attribute does not apply to any entity
This happens here as ``--gnu`` option of ArmCC is being used, which
enables the GNU compiler extensions that the ARM compiler supports.
This is solve by adding a extra check on __CCARM .
