I want to make a task in the class but I keep on getting round robin errors, Round robin is that I solve one error and another error pops up, solve that error and another error pops up. The errors start with a message about a thing do about a static function. As you can see, I want to make this last function into a task that can be triggered by the int myMPU9250::fGetAll( ) function.

Any suggestions, ideas, concepts, solutions?

Re: vTask in a class?
