return an array from a function in Arduino is by using static arrays. Although it’s not possible to directly return an array by value in C/C++, returning a pointer to a statically declared array is feasible. This pointer can be used to access the array elements outside the function ...

Dim x As ValueTuple = GetWindowProperties("DataWindow") which gives an error message that the return of GetWindowProperties cannot be converted to a ValueTuple. So my questions are: - How do I write the line that calls the GetWindowProperties function? - How do I use a named tuple in ...
That was the reason i wanted to have an option to be able to pass a custom param from ESP32 to HA using zigbee. That way i can add many more different devices and program just what key/value to pass to HA using Zigbee. Like: ...
(CALL) instruction, that is the calling function (caller). When we see it from memory point of view, this high-level abstraction of function is implemented with the help of thestack. A stack is a portion of memory that has been allocated for function to operate. The term astack frame...

In this case, we declare the local struct variable in the findMaxMin function scope and return it by value to the main routine. The struct variable can also be initialized in the main function and passed to the findMaxMin by reference to store the result values there....
