|
|
* 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.
