Hi,
the following code will fail to compile. (It only compiles, if I uncomment the const
.)
#include <iostream>
#include "StaticFunction.h"
struct Func1
{
int operator()(int val) // const
{
return val * 2;
}
int a[10];
};
struct Func2
{
int operator()(int val) // const
{
return val * a;
}
int& a;
};
typedef embxx::util::StaticFunction<int(int), 48> embxx_util_StaticFunction;
int main()
{
embxx::util::StaticFunction<int(int), sizeof(Func1{})> f1(Func1{});
std::cout << f1(3) << std::endl;
int a = 4;
embxx::util::StaticFunction<int(int), sizeof(Func2{a})> f2(Func2{a});
std::cout << f2(3) << std::endl;
return 0;
}
Compilation error is

(See it on Wandbox here.)
To get it to compile I need to change the functors' operator() to const
, i.e.
struct Func1
{
int operator()(int val) const
// .................
}
struct Func2
{
int operator()(int val) const
// .................
Anyway... I tripped over this, when trying to get your embxx::util::StaticFunction
to work with a benchmark. See here: https://github.com/user706/CxxFunctionBenchmark/tree/embxx . (It will only compile, if I put in the const here and here)

Hi!
At the moment, Timer
class is a simple deadline timer. Using it we can implement something like periodic timer, but in my opinion it is not a performance-optimal solution:
void SomeClass::periodicTask()
{
/* do some work */
timer.asyncWait(std::chrono::seconds(1),
[this](const auto& errorStatus)
{
if(errorStatus) // optional - stop the interval
{
/* LOG_ERROR(...) */
return;
}
periodicTask();
});
}
void SomeClass::start()
{
timer.asyncWait(std::chrono::seconds(1),
[this](const auto& errorStatus)
{
if(errorStatus) // optional - stop the interval
{
/* LOG_ERROR(...) */
return;
}
periodicTask();
});
}
Correct me, if I'm wrong, but I think this code is re-assigning callback to the StaticFunction
object every second. It is arleady not needed, because the callback is always the same. Additionally, body of the callback's lambda will be repeated. It would be nice to have solution like this:
void SomeClass::periodicTask()
{
/* do some work */
}
void SomeClass::start()
{
interval.start(std::chrono::seconds(1),
[this](const auto& errorStatus)
{
if(errorStatus) // on error, interval is stopped, but it can be restarted
{
/* LOG_ERROR(...) */
interval.restart();
return;
}
periodicTask();
});
}
Periodic timer would be very useful to implement cyclical tasks using e.g. SysTick. It can be of course implemented using current Timer
class, but the problem of reasigning the same callbacks every time is still not solved. On the other hand, I'm not sure, if current TimerMgr
driver is suitable to implement this feature... Maybe another Timer driver has to be implemented? What do you think about this?
Hello,
Dropbox suffers from "security issues" and various IT team just block it.
Could you move the documentation somewhere else ?

Hi!
In my embedded application, which is based mainly on your EventLoop
, I have to use 3rd party library. This library is written in pure C and needs to be polled from main loop cyclically:
while(1)
{
...
library_runOnce();
...
}
There is a need to extend EventLoop
, by adding something like runOnce()
. It will be similar to the Boost::Asio's io_service::run_one()
or ROS's ros::spinOnce()
. It has to execute only one event and return back to the caller. I have implemented this, by adding to the EventLoop
code like this:
template <std::size_t TSize,
typename TLock,
typename TCond>
void EventLoop<TSize, TLock, TCond>::runOnce()
{
lock_.lock();
auto lockGuard = embxx::util::makeScopeGuard(
[this]()
{
lock_.unlock();
});
volatile bool empty = queue_.isEmpty();
if (empty) {
return;
}
auto taskPtr = reinterpret_cast<Task*>(&queue_.front());
auto sizeToRemove = taskPtr->getSize();
lock_.unlock();
taskPtr->exec();
taskPtr->~Task();
lock_.lock();
queue_.popFront(sizeToRemove);
}
It has of course one serious disadvantage: it is not invoking cond_.wait(lock_);
, but it allows now to use EventLoop
with 3rd party libraries:
while(1)
{
library_runOnce();
_evenLoop.runOnce();
}
I think it would be nice to have this feature in embxx
.
In the README you have said, that this library is not using exceptions. When I tried to compile simple program, that uses your EventLoop
(which has inside a StaticQueue
object) with explicity disabled exceptions (-fno-exceptions
) I got an error, because there is throw used (StaticQueue.h:242):
ConstReference at(std::size_t index) const
{
if (index >= size()) {
throw std::out_of_range(std::string("Index is out of range"));
}
return (*this)[index];
}
Maybe do you just replace this statement with GASSERT(index < size());
and then leave operator[]
without any assertion?
By the way, great work - awesome library!

With code similar to this:
class i2c_slave {
typedef embxx::util::StaticFunction<void(uint8_t *)> rx_complete_t;
rx_complete_t rx_complete;
}
I'm getting this error message:
In function `embxx::util::StaticFunction<void (unsigned char*), 12u>::InvokerBound<display_ctrl_i2c::display_ctrl_i2c()::{lambda(unsigned char*)#2}>::~InvokerBound()':
../thirdparty/embxx/embxx/util/StaticFunction.h:353: undefined reference to `operator delete(void*, unsigned int)'
which was kinda surprising given the name of the class. Am I using the class in a bad way or what am I missing?
Hi,
related to #19 (and thus using code from branch develop) ... I'm just meddling with a similar library (ref),
and came across an issue, that affects StaticFunction
as well:
// ...
#include <iostream>
struct Func {
void operator()() const {
std::cout << "const ";
}
void operator()() {
std::cout << "nonconst";
}
};
int main()
{
{
Func func{};
embxx::util::StaticFunction<void(), 32> f(func);
f();
std::cout << "\t should get ";
func();
std::cout << std::endl;
}
{
const Func func{};
embxx::util::StaticFunction<void(), 32> f(func);
f();
std::cout << "\t should get ";
func();
std::cout << std::endl;
}
}
This prints
nonconst should get nonconst
nonconst should get const
So with the mutable
(ref)... the void operator()() const
is not called in the end...
Thanks for the awesome library, this will definitely come in handy!
I tried the link in the README file and it looks like it's no longer active (https://dl.dropboxusercontent.com/u/46999418/embxx/index.html). Could you please update it?
Thanks again!
Mike
I am currently using gcc 5.x which caused some breakage in the c++11 support (reference https://gcc.gnu.org/gcc-5/porting_to.html). This affects this code base, I found few issues so far, therefore I ask before I do any bug fixing in this area.
A question - move to gcc 5, or stay within gcc 4 ? The decision shall be documented in the readme
Hello. Congratulations for the work.
I am aware of it researching the use of C ++ in embedded systems, then found his book on gitbook and became interested in following your suggested steps.
I tried to compile the embedxx on my machine, but I'm in trouble.

Placeholder issue for future:
Support Clang. ref
Regarding cmake:
https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-using-clang
https://github.com/labapart/polymcu/blob/master/CMakeLists.txt
Why many macros in the CompilerOptionsFuncs cmake contain condition if (UNIX) ? Is there any intention?
An example:
macro (embxx_disable_exceptions)
if (UNIX)
embxx_add_cxx_flags("-fno-exceptions -fno-unwind-tables")
endif ()
endmacro ()
I would like to remove that UNIX, because I don't think those flags contain anything specific for UNIX. I'll send PR shortly removing it from there
