I want thoto run them at the same time but in a different loop.
First of all, you can only do one thing at a time. So that's out.
Secondly, to run multiple loops sequentially (one at a time), it is fairly easy:
void loop1(void) {...}
void loop2(void) {...}
...
void loop(void) {
loop1(); //run loop1
loop2(); //run loop2
...
loopn(); //run loopn
}
Whether it works will depend on how you have coded those loops.
