RasPi: drop draw() and have main() instead?

davenull

how to drop the function draw() and have the standard function main() instead like the way it's common to C/C++ ?

GoToLoop

noLoop() turns off auto-callback of draw():

We can also take full control of Processing by implementing our own main():

public static void main(String[] args) {
  new Your_Own_Independent_Class();
}

no, actually not. What I was missing so far, was: although Processing Sketches look like the Arduino Sketches, it's appearently not using C/C++ like the Arduino IDE does. But I'm always coding just in C/C++ (either native gcc or C/C++ via the Arduino IDE), never anything else. So I have to apologize that I didn't recognize that before.

There's also openFrameworks.cc which relies on C++:

thanks, but I was searching for something straight and simple like the Arduino IDE for Sketch C coding, most wishful as a cross compiler like for Arduinos, providing multitasking. That's how I'm doing it so far....

 #include <DueTimer.h>
 #include <Scheduler.h>

 int main() {                             
     setup();

     // attach and start Timer Interrupts
     // attach and start multitasking Scheduler loops

     if(...) {while(...) loop1();}
     else 
     //...
 }
