The callback class can now accept generalized function-objects:
class Thing {
public:
int value;
void operator()() {
printf("hi! %d\n", value);
}
};
Callback<void()> cb(Thing(2));
However, with the intention of avoiding implicit dynamic-memory
allocations, the Callback class is limited to a single word of storage.
Exceeding this size will eliminate the function-object type from the
overload set and fail to compile.
Effort was invested to make this situation very clear to the user. Here
is an example error message with noise removed:
[ERROR] ./main.cpp: In function 'int main()':
./mbed-os/hal/api/Ticker.h:101:10: note:
no known conversion for argument 1 from 'BigFunc' to 'mbed::Callback<void()>'
The real benefit of this change is the ability for users to hook into
the attributes of the Callback class. This mostly allows lifetime
management of the function-objects from third-party libraries (such as
the Event class from mbed-events).
Note: The convenient `callback` function may become ambiguous if
provided with a type that defines multiple incompatible `operator()`
member functions.
This allows additional attributes to be attached to the internally
generated type such as move and destructor operations with no increase
in RAM footprint.
The current overloads can't take advantage of this, but it does open
the possibility for more powerful overloads that can provide these
additional attributes.
Changes to mbed-os memory consumption:
.text .data .bss

after 57842 2292 7691
Enable the low power timer for the following targets:
- NUCLEO_F411RE
- NUCLEO_F401RE
- DISCO_F429ZI
- NUCLEO_F446RE
- NUCLEO_F410RB
- DISCO_F469NI
- NUCLEO_F446ZE
- B86B_F446VE
This change allows a port to provide its own implementation of:
* core_util_critical_section_enter
* core_util_critical_section_exit
Some system like the NRF series require specific behavior for the critical
section and now can override it properly.

Before:
Callback<void()> a = callback(obj, member)
Callback<void()> b = callback(context, function)
After:
Callback<void()> a = callback(obj, member)
Callback<void()> b = callback(function, context)
This ordering is more intuitive based on feedback from users. This order
was initially considered but proved problematic when integrated with
other variable arguments in attach functions.
With `callback` as a separate convenience function, this style
no longer presents a problem.
As per reference manual, closing communication for master receiver
with repeated start requires, after reading second last data byte
(after second last RxNE event):
-Clearing ACK bit (same as non repeated start case)
-Set START bit (instead of STOP bit in non repeated start case)
This is valid for I2C_FIRST_FRAME and I2C_NEXT_FRAME conditions
Disintegrate global RTX target config. Move per-target fragment

One mbed_rtx.h is defined for each vendor at this moment, however,
the granularity of mbed_rtx.h can be per-chip, or per-board
if necessary.

1. Use function pointer for interrupt handler, this should reduce the code-size
for applications that do not use this driver
2. Fix the wait for initialization of the SD card
3. Fix SDHC driver support for non-word aligned accesses
4. Remove some redundant code & assert function calls.
5. Updated various comments

Following discussion on:
it seems now clear that the transfer API is meant to be used either
with only Rx, or only Tx or Rx and Tx with the same lenth.
Therefore we're removing support of transfers of Rx and Tx with different
lenghts - this makes porting to HAL more direct and simpler.
This commit is highly derived from an existing work from salkinium.
It adds SPI ASYNC support to STM32 F4 devices. This required a small
rework of the structure to have SYNCH and ASYNCH co-exist.
The board has a jumper that be used to select between using ethernet
or using SPI for the same pin.
Without this patch, a user that configures the board in 'SPI' mode
would get a "pinmap not found for peripheral" error.
With this change a user doesn't have to change the mbed library
when switching modes
(of course user has to take care of SW and HW matching...
SPI wouldn't work as expected if board is configured in Ethernet)
This change allows program which doesn't use the IO subsystem to
completelly get rid of it in the binary generated.
IO's are still flushed by default but it can be overriden in
configuration.
Silence the following compiler warning:
Compile: SerialBase.cpp

This change avoid inclusion of printf and friends code in a binary when it
is compiled with the macro NDEBUG enabled (this macro is usually enabled
for production builds).
Unlike assert, the error function will still crash/halt the execution of the
application even if NDEBUG is enabled; the traces are just not outputed.
Move common device_has attributes into MCU_NRF51 and
MCU_NRF51_UNIFIED. This ensures all nrf51 devices have the correct
features enabled. Any devices that want to explicitly disable features
should use device_has_remove.
