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
