-# Some questions
-## Question 1
-`If you print CPU statistics at the end of every major cycle (in the super-loop), what CPU usage do you observe? How can you explain the observed CPU uptime?`
-
-We observe a 100% usage because on each CPU cycle it compare if time is done.
-
-## Question 2
-`If you run the program after the change from busy wait to sleep calls, what CPU usage do you observe? How can you explain the observed CPU uptime?`
-
-We can observe only a usage of 75% because the CPU is more on Idle with Thread sleep.
-
-## Question 3
-`If you run the static_scheduling_with_event program, what CPU usage do you observe? How can you explain the observed CPU uptime?`
-
-We observe a light usage of 1% of CPU. The CPU is now sleeping all the time and doing small task only on event.
-
-## Question 4
-`When you run multiple tests for computing the response time of the reset event, what do you observe? Is there an improvement as compared to the static_scheduling::BikeSystem implementation?`
-
-`    - If you do not press long enough on the push button, the event may be missed and no reset happens.`
-
-`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.
-
-# Multi-tasking
-
-## Question 1
-We have computed the elapsed time between the event is sent by the interruption until it is executed :
-
-|Rtos priority            |time   |
-|---|---|
-|osPriorityBelowNormal    |13 usecs   |
-|osPriorityNormal         |13 usecs   |
-|osPriorityAboveNormal    |13 usecs   |
-
-To abtain these values, we have to consider that there is a isr thread. He dispatchs all the events from the gear device and the reset device. The rest is processed by the main thread.
-
-Main of the time, it meares these values. But sometimes, higher values can appear. These values doesn't change because there isn't often more than one event in the queue.
-
-# 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
