 `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
