[req] implement passing of function arguments

[duraki]

Very nice lib, and quite simple to use. Thank you.

Could you add passing function arguments to the .setTimer( ... ) calls?

Hello,
Thank you for using the library. I am glad you liked it.
I thought of adding this feature before but I couldn't find a good way of implementing it. Since the functions are not called when the timer is created but rather the library calls the functions when it is the right time. This means that I need to store this data somewhere until the timer is called and free that memory when the timer is destroyed. Which is dynamic memory allocation and not very possible in Arduino. I generally use global variables to store such data albeit it is not a very good practice. You can use structs named similar to your functions to hold them in a packaged way and fill it before setting the timer. I don't know any other way of doing it, but open to suggestions if anyone has one.

Thanks a lot for prompting my question and the quick response! Could you provide a minimal example for passing or using struct args?

I am on the phone, so I can't guarentee it will compile but you just need to put any variable or a struct in the global space and use it later. Remember that you can change the struct contents at any point inside the program, so be careful how you use it. It should be something like this;

#include <MultiTasking.h>  //Including the MultiTasking library

typedef struct {
   int howMany;
   float value;
} FuncParams;

FuncParams myFunctionParameters;

void setup() {
  Serial.begin(9600);  //Starting serial interface at 9600 bauds

  //Set what you are going to use inside the function
  myFunctionParameters.howMany = 5;
  myFunctionParameters.value = 0.75;

  superTask.setTimer(helloWorld, 1000, 0);  //Setting a timer to call hello world function every second forever
  superTask.startTasks();  //Starting the MultiTasking library
}

void loop() {
}

void helloWorld() {  //Defining a function named as "helloWorld"
  Serial.println("Hello, World!"); //Printing "Hello, World!" over serial
  Serial.print("Count: ");
  Serial.print(myFunctionParameters.howMany);
  Serial.print("Val: ");
  Serial.print(myFunctionParameters.value);
  Serial.println(); //send a newline
}
