How you write and ersae the flash on the NRF52 changes depending on
whether the SoftDevice is enabled or not.
This change does a runtime check before erasing and writing, and
then chooses the correct function to perform the action.
Read By group type response can return 4 descriptor discovered when the remote server have 4 descriptors with a 16 bit UUID. The handle, UUID pair get stored in a ble_gattc_desc_t that is 20 bytes long.
This PR increase buffer size to handle this use case.
hal_critical_section_enter() is safe to call multiple times, however
hal_critical_section_exit() is only called on the last exit from a
critical section. This will cause a mismatch in the counter and the
interrupt state will never be restored if the critical section is
nested. Change this to a bool so that the interrupt save state is
tracked for hal_in_critical_section() to work correctly.
Call underlying HAL implementation to enter critical section/disable interrupts
before incrementing the global critical section counter.
Modify HAL implementations to track first entrances to the critical section and
only update the saved state on first enter.
which can be called from diferent contexts.
Orginal nordic critical primitives must been called in pairs
from exacly the same function. As mbed hal call it in separate
methods, so they are not suitable here.
signals are lost. It was observed at last for tests-api-spi ci-test-shield's
test.
This patch introduce usage of sdk5 origin implementation in which
sd_nvic_critical_region_enter/exit is calling each time critical region
is enter/exit. This fixes the issue.
For api usage like DigitalOut led(LED1, 1) the hal function gpio_write()
sets the output before f. gpio_mode() is called. gpio_mode() clears the
output as it take never writen parameters (gpio_cfg_t.init_hight).
This patch use internal hardware register of GPIO output instedad of above paramiter latch
for retaining proper writen state.

I'm not sure if if there are any copyright issues here with what is
effectively a set of config files. A few folks have been bugging me (and
the redbear folks) for these changes, so I wanted them somewhere
centralized.
Change implementation of timeout to one that is using us_ticker hal.
Timeout is now configurable by I2C_TIMEOUT_VALUE_US macro and this
value will be imported if will be defined externaly.
The allocation of GPIOTE channels for DigitalIn is unwanted behavior.
This caused early run-out of channels for InterruptPin.
This patch replacing input configuration that is using gpiote driver by configuration that is
using gpio hal.
Previous the voltage range was set to 1.2 from SoC internal reference source.
This caused problem with testing. It is unexpected that range is much
shorter than vdd as well.
The voltage range was extended using SoC build in analog prescaler (set to 1/3).
Some Cortex-M0 devices, such as the nrf51, don't have the SysTick.
Instead, these targets use a software interrupt to simulate SysTick.
Add the hooks in the tickless code to support these devices. Targets
which do not have SysTick should now define NO_SYSTICK in targets.json
and implement mbed_get_m0_tick_irqn to add os suport.
This patch also removes os tick handling from the existing devices
(nrf51) since this is now handled in common code.
fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.
set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.
It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.
The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)
All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.
The symbol Systick_Handler was defined as a weak symbol in us_ticker.c and
startup_nRF51822.s. While it work as expected when an application is compiled
from mbed OS source code it creates a duplicate symbol issue when mbed OS is
bundled as a library.
