            C++11 multithreaded cancellable slice-based work
            Asked 2022-Apr-17 at 18:39

            I am trying to create a base class to manage a slice-based workload.
            My approach was to create a base abstract class that handles the initialization/termination of the work and inherit from that class in specific classes that only specify the actual work and timings.
            I also added the functionality in the base class to reinitialize the workload if a set number of errors occur.

            This works as expected in a simple example (given below) and with most workloads that I have but when I try to use this with a specific workload (reading a serial port that's written to by an arduino) it completely messes up the stream read from arduino.
            I suspect there is some problem with my approach but I couldn't figure it out...

            Here is my code:

            General Observations:

            While the code compiles and runs on Windows 10 in Visual Studio 2019, there are multiple problems here, not necessarily with threading.

            1. Without knowing what the expected output for the test case it is very difficult to determine if the code is running correctly.
            2. Object oriented programming rules are being broken, there doesn't seem to be any encapsulation. All of the variables and methods are public.
            3. This looks more like C code that C++ code except for the classes themselves.
            4. I am providing a review to address the C++ issues, we don't debug problems on code review, and we would need to see the the Arduno code to help debug it (on Stack Overflow, not Code Review).
            Avoid using namespace std;

            If you are coding professionally you probably should get out of the habit of using the using namespace std; statement. The code will more clearly define where cout and other identifiers are coming from (std::cin, std::cout). As you start using namespaces in your code it is better to identify where each function comes from because there may be function name collisions from different namespaces. The identifiercout you may override within your own classes, and you may override the operator << in your own classes as well. This stack overflow question discusses this in more detail.

            Never put using namespace std into a header file.

            Declare Public Variables and Methods at the Top of the Class

            A general best practice is to declare public variables and methods at the top of the class followed by the protected variables and methods and then finally the private variables and methods. This makes it easier for the users of the class to find the interfaces they need.

            While the C++ language does provide a default for variables and methods declared at the top of the class, the code is easier to read and maintain if the public, protected and private keywords are explicit.

            Prefer C++ I/O Over C Programming I/O

            While C++ is backward compatible with C, using printf() in C++ is exceptionally rare, std::cin and std::cout are preferred in C++.

            A Base Class Does Not Need to be an Abstract Class

            You can provide default functions for the virtual methods init() and oneSliceWork(). This would reduce the repetition of code in the test case, and still allow for the virtual methods to be overwritten when necessary.



            Sending int from python to arduino, but there is an upper limit. How do I solve it?
            Asked 2022-Mar-29 at 10:02

            in my project I am sending int from python to arduino, which is the number of steps the stepper motor should take. Python code:



            Answered 2022-Mar-29 at 08:55

            I would assume that the limit is exactly 32767 which is 2**15 - 1. This is a hint that on Arduino parseInt return a 16 bits, 2's complement integer.

            If you have a larger integral type (long ?) on Arduino, you should try to use it. An alternative would be to use a different encoding passing two integers each 15 bits max. At the end you would loop high value times 32767 times + low value times.

            How to filter a class in Angular?
            Asked 2022-Feb-04 at 16:12

            I'm trying to show in a list the projects whose method "arduino" is equal to true (it's a boolean).

            I tried to do *ngFor and *ngIf on the same line but it gives an error, so when doing it on another line, the system loads the projects whose method "arduino" is equal to 'false' too, so it doesn't work well

            How can I filter it from component.ts so that only projects with method project.arduino = true are loaded?

            Here is the code in component.ts

            I think if the method "arduino" is a boolean you only need to do something like :



            Reading Arduino Serial data on C# application but port access denied?
            Asked 2022-Feb-01 at 21:45

            When I connect my Arduino to my laptop and want to get serial data on my system, I get an exception about port access being denied. I am sure about the port number (COM4) and opening and closing ports. sometimes I reconnect the device it works.



            Answered 2022-Feb-01 at 21:45

            Try these out:

            • if your Serial monitor on Arduino is not opened, be sure to close it.

            • check the port in system management of your system to be sure about the port number again.

            • be sure about closing your application each time you want to test, because running an application will reserve the port and will not let other apps use it.

            when I resize my window my text is overlapping. How do I stop this from happening? I want it to just resize if it colliding with the other text elements or, if not possible, that they just stack under each other? problem

            Answered 2022-Jan-28 at 09:25

            A way to fix your problem is using flex box, but this time add a part in the css where once the screen gets to a certain size, the flex-box goes from row, to column. Like this:



            What is the Rust equivalent of Serial.println from the Arduino C++ API?
            Asked 2022-Jan-27 at 18:21

            A common pattern in Arduino C++ sketches is the use of Serial.print() or Serial.println() to debug problems.

            What is the corresponding Rust idiom when programming for the Arduino Uno?



            Answered 2022-Jan-27 at 18:21

            One technique involves the use of arduino_hal::default_serial! and ufmt::writeln!

            To make your ESP32 board go into flashing/uploading mode automatically, you can connect a 10 μF electrolytic capacitor between the EN pin and GND. When I had the same problem, when I followed this advice, the problem was solved.




            How to make an object take and store an Array of arbitrary, but compile-time known size?
            Asked 2022-Jan-20 at 15:19

            For an embedded project, I want a class that takes a list of structs. This list is known at compile-time, so I shouldn't have to resort to dynamic memory allocation for this.

            However, how do I make a struct/class that encapsulates this array without having to use its size as a template parameter?


            My first idea was to do exactly that:



            Answered 2022-Jan-20 at 15:12

            Is there a way to 'hide' the size of the array in Profile or Runner?

            Yes. The solution is indirection. Instead of storing the object directly, you can point to it. You don't need to know the size of what you're pointing at.

            A convenient solution is to point into dynamic storage (for example std::vector) because it allows you to "bind" the lifetime of the dynamically sized object to a member. That's not necessary in general, and you can use automatic storage instead. However, in that case you cannot bind the lifetime of the pointed object, and you must be very careful to not let the pointed object be destroyed before you stop using it.

            The indirection can be done at whatever level you prefer. If you do it at the lowest level, you simply store the array outside of Profile. In fact, if all that profile does is contain an array, then you don't need a class for it. Use a generic span:
