`Based on the program itself and on the task scheduling, explain these two behaviors. Explain also why such behaviors may be problematic.`
We notice, that we miss such less event when is event driven (or not at all). But with a static scheduling the response time is still long because the reset task is call with a certain period.

# Issues
When compile with GCC, the full loop of static scheduling is 2 to 3 ms faster than expected.
This problem doesn't occur if we compile with ARMC6.
As the acceptable delta is 2ms and the teacher test is done with GCC, we modify the delta on the test to be 3ms
