Calls to Timer::attach() are inlined in order not to use floating-point
library functions calls given Timer::attach_us() expects an integer
for the callback interval.
* Create new `s_timestamp_t` type to specify timestamp is seconds
* Alter `attach()` API to expect `s_timestamp_t` for interval value
* Create helper macro to convert seconds to milliseconds and help code
readability
* Modify Greentea tests accordingly
* Modify Doxygen grouping of `drivers` Public/Internal APIs
* Correct classification of `mbed_events.h`
* Amend name of Doxygen group containing Device Key API
* Classify `CallChain.h` as public API and relocate file
* Remove Doxygen group from `equeue_platform.h` as it has no Doxygen compliant documentation
* Move USB target specific code back to `usb/device/targets`
* Fix rtos include path in NRFCordioHCIDriver
* Flatten USB driver directory structure
* Add missing include for us_ticker
* Add more missing includes for us_ticker
* Fix mbed_hal_fpga_ci_test_shield/uart test
* Fix bare-metal build
* Fix Watchdog UNITTEST
* Fix Mbed OS 2 build for Public/Internal headers relocating
* Change Doxygen groups structure, splitting first by Public/Internal
This commit also does the following:
* groups the documentation of related API
* moves `events/internal/equeue.h` to `events/equeue.h`
* merges `events/source/README.md` to `events/README.md`
The contents of the usb directory were moved to appropriate locations and the usb directory removed.
* Public USB headers moved under drivers/
* Internal USB headers moved under drivers/internal/
* USB Source code moved under drivers/source/usb/
* Moved usb/device/hal/ under hal/usb/
* Moved usb/device/USBPhy/ under hal/usb/
* Merged usb/device/targets/ into targets/
* Separated public and private USB API documentation under Doxygen groups drivers-public-api and drivers-internal-api.
Also includes:
* rename `mbed_sleep_manager.c` to `mbed_power_mgmt.c` to match its
header file
* create Doxygen groups for public and internal APIs
* use relative path to include header files where inconsistent
* update references to internal APIs throughout libraries
* update the copyright year for all modified files
Separate drivers, events, and rtos internal APIs from public APIs.
* Move source files to source subdirs
* Move internal headers to internal subdirs
* Add Doxygen comments for documenting internal and public APIs
* Remove source code from header files in order to remove include pre-processor directives
that included header files not directly used by said header files
* Explicitly include header files instead of implicit inclusions via third-party header files.
Release Notes
This will break user code that was using an internal API as the internal header files have been moved.
This will only break if the user was including the header file using a namespace (i.e #include "foo/bar.h" instead of #include "bar.h"
* Adjust definition to make the default constructor `constexpr`.
This permits use in classes that want lazy initialization and their
own `constexpr` constructor, such as `mstd::mutex`.
* Add `get_no_init()` method to allow an explicit optimisation for
paths that know they won be the first call (such as
`mstd::mutex::unlock`).
* Add `destroy()` method to permit destruction of the contained object.
(`SingletonPtr`'s destructor does not call its destructor - a cheat
to omit destructors of static objects). Needed if using in a class
that needs proper destruction.
We will provide documentation how to create your own VirtualWatchdog. It's simple,
create timeout and watchdog objects.
This class brought lot of discussion and questions. After our refactor we made this class
just a linked list of objects - something tickers can do as well (they already have linked list) and handling hw should be
done via Watchdog due to the limitations (timeout can be set only once per app!).
Watchdog can handle callbacks - VirtualManager can attach to the tick. This should simplify the logic.
Watchdog can tick on its own using tickers.
VirtualWatchdog uses attach to get a callback when Watchdog ticks - to process own
linked list of virtual watchdogs.
Watchdog should be usable on it's own - kicking it via ticker. No Virtual involved.
VirtualWatchdog as well - services should use this one to have multiple one in the system.
There's WatchdogManager - basically internal class to manage ticker for Watchdog.
Refactor old Watchdog (it was not a driver) to become VirtualWatchdog.
This is software virtual watchdog. This it the primary used watchdog in user application.
VirtualWatchdog: has-a watchdog. Initializes hw watchdog - start it when first used, stops it when there is no more VirtualWatchdog in the system -
list is empty.
Adding also check to watchdog to make sure there is only one in the system - runtime error if multiple objects created to already
running hw watchdog.
Watchdog is hardware driver. It interacts with HAL - provides wrapper to interact with the peripheral.
Provides basic functionality: start/stop, get timeout/max timeout.
It is automatically kicked by a timer, according to the timeout set in ctor.
Without freeing the DAC, the pin will continue to be configured as DAC. Which make it impossible to change it from Analogout to anything else.
Check this code that allow you to change the AnalogOut to DigitalOut
<<code>>
#include "mbed.h"
class myAnalog : public AnalogOut{
public:
myAnalog(PinName myname);
~myAnalog();
PinName _myname;
};
myAnalog::myAnalog(PinName myname):AnalogOut(myname),
_myname(myname){
;
}
myAnalog::~myAnalog(){
analogout_free(&this->_dac);
}
myAnalog *x=0;
DigitalOut *xx=0;
void do_something_analog() {
x=new myAnalog(PA_4);
double g=0.0;
while(g<0.5){
x->write(g);
g=g+0.1;
wait_ms(50);
}
if (x!=0){
delete x;
x=0;
}
}
void do_something_digital() {
xx=new DigitalOut(PA_4);
for(int i=0;i<10;i++){
*xx = 1;
wait_ms(50);
*xx = 0;
wait_ms(50);
}
if (xx!=0){
delete xx;
xx=0;
}
}
int main()
{
printf("\nAnalog loop example\n");
while(1) {
do_something_digital();
do_something_analog();
}
}
<</code>>
- Changed the process into static method
- used the singletonptr for creating the low power ticker instance
- Added the mbed stub into cmake build for cellularnonipsocket,loramacrypto
-Added the mock class function to mock mbed_assert_internal
-Added the unit test case to test start,kick,stop
-Modified the interface api name from is_alive to process
-added the unit test cases for process
-SW watchdog has interface name start(),stop(),kick() Sw watchdog internally has static list and shared across multiple instance of SW watchdog
- Sw watchdog initialize timeout value,unique string via constructor whenever threads created sw watchdog object
-Threads make sure pass proper timeout value,Unique string while creating the instance.
-start() called by components(BLE,WIFI etc.,),it adds the entry into static list with few details current count ,etc.,
-kick() called by registered components(BLE,WIFI etc.) to reset current count to zero.
-is_alive - interface API to mbed_watchdog_manager
-implementation optimization
-Added API to register muliple threads to watchdog drivers
-Watchdog timeout reconfigures everytime whenever new register thread with longer timeout period
-New APIs for watchdog
wd_register(const osThreadId_t tid, const uint32_t timeout) to register to watchdog
wd_unregister(const osThreadId_t tid) to unregister to watchdog
kick(const osThreadId_t tid) to refresh the watchdog
SPI peripherals' asynch transaction buffers are now wrapped by
SingletonPtr, which needs to take the singleton_lock Mutex when first
accessed. If it was first accessed by an asynch transaction started from
IRQ, that would not be possible.
Add a SingletonPtr::get() call to the SPI construction process so that
the peripheral's buffer is fully constructed before any SPI methods can
be called, meaning asynch methods won't fail from IRQ.
(Other pre-existing synchronisation issues with async remain, but this
avoids a new trap in Mbed OS 5.12).
