|
|
* This function will measure and print the CPU usage of tasks over a
|
|
* specified number of ticks (i.e. real time stats). This is implemented by
|
|
* simply calling uxTaskGetSystemState() twice separated by a delay, then
|
|
* calculating the differences of task run times before and after the delay.
|
|
*
|
|
* @note If any tasks are added or removed during the delay, the stats of
|
|
* those tasks will not be printed.
|
|
* @note This function should be called from a high priority task to
|
|
* minimize inaccuracies with delays.
|
|
* @note When running in dual core mode, each core will correspond to 50%
|
|
* of the run time.
