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.
1) if we receive more than one __sync, previous handshake would consider
it as echo_count and try to decode the value. Now we skip superfluous __sync.
2) reduce the uart load produced by the test, as we are heavily running tests in
parallel and not one-to-one this update was required.
The current mbed-os drivers rely on a tickrate of 1ms for timing.
This means that if OS_TICK_FREQ is set to any value other than 1000
then mbed-os driver will no longer delay for the correct amount of
time. To prevent this from happening this patch triggers a compile
time error if a tickrate other than 1m is used.
Add weak implementations of *_ticker_get_info which returns 1MHz and
a width of 32 bits. This allows the updated Ticker API to work with
existing devices.
Note - in the future when all targets have implemented
*_ticker_get_info these weak functions will be removed.
Allow tickers to specify their native frequency and number of bits.
This allows the conversion to happen in common code rather than in
each vendor's implementation.
The constructor doc incorrectly suggested that only short (16-bit)
UUIDs were accepted. The same doc also referred to properties
instead of characteristics. (And to "value length", which seemed to
be completely out of place in the context of the current code.)
In test_case_2x_callbacks two tickers are setup to repeatedly
reschedule each other. When these tickers are deleted this
rescheduling is still occurring and can lead to a deleted ticker
being scheduled.
When this happens the following error message is displayed:
Thread 0x0 error -6: Not allowed in ISR context
Note - this problem was not detected by CI since the test reported
the correct results back to the host test and only experienced this
error on tear down.
This problem can be reproduced on an nrf51 by first building the ticker
test with:
"mbed test -t GCC_ARM -m NRF51_DK -n tests-mbed_drivers-ticker
--compile -DMBED_TRAP_ERRORS_ENABLED=1
-DMBED_HEAP_STATS_ENABLED=1 -DMBED_STACK_STATS_ENABLED=1"
And then running testing with:
"mbed test -t GCC_ARM -m NRF51_DK -n tests-mbed_drivers-ticker --run"
This commit reverts commit c1c0f1ea57
because it causes nightly builds to fail. This is because extra tests
added in tests-mbed_drivers-ticker fail on some targets, such as the
KL46Z, MAX32625MBED, MAX32630FTHR, NCS36510, NRF51 and NRF52_DK.
Spinning while polling is overly CPU intensive, and inconsistent with
the current blocking behaviour of UARTSerial.
Change to use Thread::wait(1) to match UARTSerial.
If a LowPowerTimer is started and then goes out of scope then a
deep sleep lock underflow can occur. This is because the
the variable '_lock_deepsleep' is checked when starting the timer
but is not checked in the destructor, which unconditionally releases
the deep sleep lock.
